RADIUS authentication attributes

1

User-Name

Refers to the user to be authenticated in the Access-Request. The format for IPoE/PPPoE hosts depends on configuration parameters pppoe-access-method, ppp-user-name, or user-name-form at in the CLI context configure subscriber-mgmt authentication-policy name. The format for ARP-hosts is not configurable and always the host IPv4-address. The format for S11 GTP Sessions is based on the PAP username signaled in the Protocol Configuration Options (PCO) in the GTP Create Session Request message, if no PAP username is present the username is based on the gtp-user-name configuration under configure subscriber-mgmt authentication-policy name. The RADIUS User-Name specified in an Access-Accept or CoA is reflected in the corresponding accounting messages.

2

User-Password

The password of the user to be authenticated, or the user's input following an Access-Challenge. For PPPoE users it indirectly maps to the password provided by a PPPoE PAP user in response to the PAP Authenticate-Request. For IPoE/ARP hosts it indirectly maps to a preconfigured password (configure subscriber-mgmt authentication policy name password password or configure aaa isa-radius-policy name password password).

3

CHAP-Password

Provided by a PPPoE CHAP user in response to the CHAP challenge. The CHAP challenge sent by the NAS to a PPPoE CHAP user is part of the CHAP authentication sequence RFC 1994, PPP Challenge Handshake Authentication Protocol (CHAP), (Challenge, Response, Success, Failure). The user generated CHAP password length is equal to the defined Limits and contains a one byte CHAP-Identifier from the user's CHAP Response followed by the CHAP Response from the user.

4

NAS-IP-Address

The identifying IP Address of the NAS requesting the Authentication. Included when the RADIUS server is reachable using IPv4. The address is determined by the routing instance through which the RADIUS server can be reached:

‟Management” — the active IPv4 address in the Boot Options File (bof address ipv4-address)

‟Base” or ‟VPRN” — the IPv4 address of the system interface (configure router interface system address address)

The address can be overwritten with the configured source-address (configure aaa radius-server-policy policy-name servers source‑address ip-address).

5

NAS-Port

The physical access-circuit on the NAS which is used for the Authentication of the user. The format of this attribute is configurable on the NAS as a fixed 32 bit value or a parameterized 32 bit value. The parameters can be a combination of outer and inner vlan ID, slot number, MDA number, port number, lag-id, pw-id, pxc‑id, pxc-subport and fixed bit values (zero or one) but cannot exceed 32 bits. The format can be configured for following applications: configure router l2tp cisco-nas-port, configure service vprn service-id l2tp cisco-nas-port, configure subscriber-mgmt authentication-policy name include-radius-attribute nas-port.

6

Service-Type

The type of service the PPPoE user has requested, or the type of service to be provided for the PPPoE user. Optional in RADIUS-Accept and CoA. Treated as a session setup failure if different from Framed-User.

7

Framed-Protocol

The framing to be used for framed access in case of PPPoE users. Optional in RADIUS-Accept and CoA. Treated as a session setup failure if different from PPP.

8

Framed-IP-Address

The IPv4 address to be configured for the host using DHCPv4 (RADIUS proxy), IPCP (PPPoE), or data-triggered subscriber management. [8] Framed-IP-Address attribute with value different from 255.255.255.254 has precedence over [88] Framed-Pool when both are present in RADIUS Access-Accept. [8] Framed-IP-Address with value 255.255.255.254 is ignored in RADIUS Access-Accept (the NAS should select an address for the user). Attribute is also used in CoA and Disconnect messages (part of the ESM or AA user identification key).

9

Framed-IP-Netmask

The IP netmask to be configured for the user when the user is a router to a network. For DHCPv4 users, the attribute maps to DHCPv4 option [1] Subnet mask and is mandatory for numbered subscriber hosts if [8] Framed-IP-Address is also returned. A subnet mask is autogenerated for unnumbered subscriber hosts when not obtained from authentication. For PPPoE residential access, the attribute should be set to 255.255.255.255 (also the default value if the attribute is omitted). For PPPoE business access, the attribute maps to PPPoE IPCP option [144] Subnet-Mask only when the user requests this option and if the node parameter configure subscriber-mgmt ppp-policy ppp-policy-name ipcp-subnet-negotiation is set.

18

Reply-Message

Text that may be displayed to the user by a PPPoE client as a success, failure or dialog message. It is mapped to the message field from the PAP/CHAP authentication replies to the user. Omitting this attribute results in standard reply messages: login ok and login incorrect for PAP, CHAP authentication success and CHAP authentication failure for CHAP. String length greater than the defined Limits are accepted but truncated at this boundary.

22

Framed-Route

Routing information (IPv4 managed route) to be configured on the NAS for a host (DHCP, PPPoE, ARP, or data-triggered) that operates as a router without NAT (routed subscriber host). The route included in the Framed-Route attribute is accepted as a managed route only if its next-hop points to the hosts ip-address, if the next-hop address equals 0.0.0.0, or if the included route is a valid classful network, in which case the subnet-mask is omitted. If neither is applicable, this specific framed-route attribute is ignored and the host is instantiated without this specific managed route installed. A Framed-Route attribute is also ignored if the SAP does not have anti-spoof configured to nh-mac (the host is installed as a standalone host without a managed route). Any routes above the configured Limits are silently ignored. Optionally, a metric, tag or protocol preference can be specified for the managed route. If the metrics are not specified, specified in a wrong format, or specified with out-of-range values, then the default values are used for all metrics: metric=0, no tag and preference=0.

If an identical managed route is associated with different routed subscriber hosts in the context of the same IES/VPRN service up to max-ecmp-routes managed routes are installed in the routing table (configured as ecmp max-ecmp-routes in the routing instance). Candidate ECMP Framed-Routes have identical prefix, equal lowest preference and equal lowest metric. The ‟lowest ip next-hop” is the tie breaker if more candidate ECMP Framed-Routes are available than the configured max-ecmp-routes. Other identical managed routes are shadowed (not installed in the routing table) and an event is logged. An alternative to RADIUS managed routes are managed routes using host dynamic BGP peering.

Valid RADIUS learned managed routes can be included in RADIUS accounting messages.

25

Class

Attribute sent by the RADIUS server to the NAS in an Access-Accept or CoA and is sent unmodified by the NAS to the Accounting server as part of the Accounting-Request packet. Strings with a length longer than the defined Limits are accepted but truncated to this boundary.

27

Session-Timeout

Sets the maximum number of seconds of service provided to the user (IPoEv4 host, PPPoE or IPoE session) before termination of the session. The attribute equals [26.6527.160] Alc-Relative-Session-Timeout when received in Access-Accept because the current session time portion is then equal to zero. Value zero sets the session-timeout to infinite (no session-timeout). The attribute is CoA NAK'd if its value is smaller than the current-session time. Simultaneous received [27] Session-Timeout and [26.6527.160] Alc-Relative-Session-Timeout are treated as an error condition (setup failure if received using Access-Accept and NAK’d if received using CoA). With IPoE sessiondisabled for IPoEv4 radius proxy and CoA create-host scenarios, [27] Session-Timeout is interpreted as lease-time instead of session-time if [26.6527.174] Alc-Lease-Time is omitted.

For WLAN-GW group interfaces, the interpretation of the Session-Timeout attribute is configured with: configure service ies | vprn service-id subscriber-interface ip-int-name group-interface ip-int-name wlangw ipoe-session radius-session-timeout {backwardscompatible | ignore | absolute}.

28

Idle-Timeout

Sets the maximum number of consecutive seconds of idle connection allowed to the user before termination of the session (IPoE/PPPoE) or a connectivity check is triggered (IPoE). Values outside the allowed Limits are accepted but rounded to these boundaries. A value of zero is treated as an infinite idle-timeout. The idle-timeout handling on the node is implemented using category-maps (configure subscriber-mgmt category-map category-map-name and configure subscriber-mgmt sla-profile sla-profile-name category-map category‑map‑name).

30

Called-Station-Id

Allows the NAS to send in an Access Request with respect to the user called. Attribute is omitted in authentication using: configure subscriber-mgmt authentication-policy name include-radius attribute no called-station-id.

Supported applications:

• LNS

  The content is the string passed in the [21] Called Number AVP of the L2TP ICRQ message.

• WLAN Gateway / vRGW

  WLAN Gateway / vRGW reflects the currently learned AP-MAC/BRG-MAC and SSID. These can be learned using EAP, DHCP (option 82), DHCPv6 LDRA (interface-id), ARP/ND over GRE or L2TP cookie. When the MAC and SSID cannot be learned because the info is not available or provided in an invalid format, then the value "00:00:00:00:00:00" is inserted.

31

Calling-Station-Id

Allows the NAS to send unique information identifying the user who requested the service. This format is driven by configuration (configure subscriber-mgmt authentication-policy name include-radius-attribute calling-station-id <llid | mac | remote-id | sap-id | sap-string>). The LLID (logical link identifier) is the mapping from a physical to logical identification of a subscriber line and supplied by a RADIUS llid-server. The sap-string maps to configure service ies | vprn service-id subscriber-interface ip-int-name group-interface ip-int-name sap sap-id calling-station-id sap-string. A [31] Calling-Station-Id attribute value longer than the allowed maximum is treated as a setup failure. The attribute is omitted in authentication using configure subscriber-mgmt authentication-policy name include-radius-attribute no calling-station-id.

32

NAS-Identifier

A string (configure system name system-name) identifying the NAS originating the Authentication requests and sent when configured: include-radius-attribute nas-identifier in configure subscriber-mgmt authentication-policy

44

Acct-Session-Id

A unique identifier that represents the subscriber host or session that is authenticated. This attribute can be used as CoA or Disconnect Message key to target the host or session and is reflected in the accounting messages for this host or session. The attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute acct-session-id [host | session]. For PPPoE, either the host acct-session-id (default) or the session acct-session-id is included.

60

CHAP-Challenge

The CHAP challenge sent by the NAS to a PPPoE CHAP user as part of the chap authentication sequence RFC 1994 (Challenge, Response, Success, Failure). The generated challenge length for each new pppoe session is by default a random value from 32 to 64 bytes unless configured different under configure subscriber-mgmt ppp-policy ppp-policy-name ppp-chap-challenge-length [8 to 64] or configure service vprn service-id | router l2tp group tunnel-group-name ppp chap-challenge-length [8 to 64] for LNS (the command can also be specified at the tunnel level). The CHAP challenge value is copied into the request-authenticator field of the RADIUS Access-Request message if the minimum and maximum value is configured at exact 16 (RFC 2865, Remote Authentication Dial In User Service (RADIUS), section 2.2, Interoperation with PAP and CHAP). Attribute CHAP-Password is provided by a PPPoE CHAP user in response to the [60] CHAP-challenge.

61

NAS-Port-Type

The type of the physical port of the NAS which is authenticating the user and value automatically determined from subscriber SAP encapsulation. It can be overruled by configuration. Included if include-radius-attribute nas-port-type is configured in: configure subscriber-mgmt authentication-policy . Checked for correctness if returned in CoA.

The NAS-Port-Type attribute is always included when the Nas-Port-Id is also included.

85

Acct-Interim-Interval

The interval, in seconds, at which Acct-Interim-Update messages should be generated for the first RADIUS Accounting Policy in the subscriber profile. Overrides the local configured update-interval value in the RADIUS accounting policy. This only takes effect if interim-updates are enabled for one of the accounting modes in the RADIUS Accounting Policy.

An attribute value of 0 disables the generation of Acct-Interim-Update messages.

Attribute [85] Acct-Interim-Interval takes precedence over [26.6527.232] Alc-Acct-Interim-IvI with tag 1 when both are included. Attribute values outside the allowed limits are accepted but are rounded to the minimum or maximum limit.

87

NAS-Port-Id

A text string which identifies the physical/logical port of the NAS which is authenticating the user. Attribute is also used in CoA and Disconnect Message (part of the user identification-key). See [87] NAS-Port-Id attribute details for a detailed description of the attribute format.

The NAS-Port-Id can have an optional prefix-string (max 8 chars) and suffix-string (max 64 chars) added (configure subscriber-mgmt authentication-policy name include-radius-attribute nas-port-id [prefix-string string] [suffix circuit-id | remote-id]).

Included only if include-radius-attribute nas-port-id is configured: configure subscriber-mgmt authentication-policy. For a capture-sap, the nas-port-id attribute is always included in authentication requests.

88

Framed-Pool

The name of one address pool or the name of a primary and secondary address pool separated with a one character configurable delimiter (configure router/service vprn service-id dhcp local-dhcp-server server-name use-pool-from-client delimiter delimiter) that should be used to assign an address for the user and maps to either:

1) dhcpv4 option [82] vendor-specific-option [9] sub-option [13] dhcpPool if option is enabled on the node (configure service ies/vprn service-id subscriber-interface ip-int-name group-interface ip-int-name dhcp option vendor-specific-option pool-name) or

2) used directly as pool-name in the local configured dhcp server when local-address-assignment is used and client-application is ppp-v4 (configure service ies/vprn service-id subscriber-interface ip-int-name group-interface ip-int-name local-address-assignment). Alternative to [26.2352.36] Ip-Address-Pool-Name and [26.4874.2] ERX-Address-Pool-Name. Framed-Pool names longer than the allowed maximum are treated as host setup failures. [8] Framed-IP-Address attribute with value different from 255.255.255.254 has precedence over [88] Framed-Pool when both are present in RADIUS Access-Accept.

95

NAS-IPv6-Address

The identifying IP Address of the NAS requesting the Authentication. Included when the RADIUS server is reachable using IPv6.

The address is determined by the routing instance through which the RADIUS server can be reached:

‟Management” — The active IPv6 address in the Boot Options File (bof address ipv6-address).

‟Base” or ‟VPRN” — The IPv6 address of the system interface (configure router interface system ipv6 address ipv6-address).

The address can be overwritten with the configured ipv6-source-address (configure aaa radius-server-policy policy-name servers ipv6-source-address ipv6-address).

97

Framed-IPv6-Prefix

The IPv6 prefix or prefix length to be configured using SLAAC (Router Advertisement) to the WAN side of the user. Any non /64 prefix-length for SLAAC host creation is treated as a session setup failure for this host. This attribute is an alternative to [100] Framed-IPv6-Pool and [26.6527.99] Alc-IPv6-Address, which assigns IPv6 addressing to the wan-side of a host using DHCPv6 IA-NA. Attribute is also used in CoA and Disconnect Message (part of the ESM or AA user identification-key).

99

Framed-IPv6-Route

Routing information (IPv6 managed route) that is configured on the NAS for an IPv6 WAN host (IPoE or PPPoE) that operates as a router. The functionality is comparable with offering multiple PD prefixes for a single host. The route included in the Framed-IPv6-Route attribute is accepted as a managed route only if its next hop is a WAN host (DHCPv6 IA-NA, SLAAC, or /128 data-triggered). Therefore, Framed-IPv6-Routes with an explicitly configured gateway prefix of a pd-host (DHCPv6 IA-PD) are not installed. A Framed-Route attribute is also ignored if the SAP does not have anti-spoof configured to nh-mac (the host is installed as a standalone host without managed route). Any routes above the configured limits are silently ignored.

Optionally, a metric, tag, or protocol preference can be specified for the managed route. If the metrics are not specified, specified in a wrong format, or specified with out-of-range values, then the following default values are used for all metrics: metric=0, no tag, and preference=0.

If an identical managed route is associated with different routed subscriber hosts in the context of the same IES or VPRN service, up to max-ecmp-routes managed routes are installed in the routing table (configured as ecmp max-ecmp-routes in the routing instance). Candidate ECMP Framed-IPv6-Routes have an identical prefix, equal lowest preference, and equal lowest metric. The lowest IP next hop is the tie breaker if more candidate ECMP Framed-IPv6-Routes are available than the configured max-ecmp-routes. Other identical managed routes are shadowed (not installed in the routing table) and an event is logged.

Valid RADIUS-learned managed routes can be included in RADIUS accounting messages.

100

Framed-IPv6-Pool

The name of an assigned pool that should be used to assign an IPv6 address using DHCPv6 (IA-NA) to the WAN side of the user (IPoE, PPPoE). Maps to DHCPv6 vendor-option [17], sub-option [1] wan-pool. Framed-IPv6-Pool names longer than the allowed maximum are treated as host setup failures. This attribute is an alternative to [97] Framed-IPv6-Prefix and [26.6527.99] Alc-IPv6-Address, that also assigns IPv6 addressing to the WAN side of a host using SLAAC or DHCPv6 IA-NA.

101

Error-Cause

The Error-Cause Attribute provides more detail on the cause of the problem if the NAS cannot honor Disconnect-Request or CoA-Request messages for some reason. It may be included within Disconnect-ACK, Disconnect-NAK and CoA-NAK messages. The Error-Causes are divided in 5 blocks. Range [400-499] is used for fatal errors committed by the RADIUS server. Range [500-599] is used for fatal errors occurring on a NAS or RADIUS proxy. Ranges [000-199 reserved], [300-399 reserved] and [200-299 used for successful completion in disconnect-ack/coa-ack] are not implemented.

123

Delegated-IPv6-Prefix

The attribute that carries the prefix (IPv6 prefix or prefix length) to be delegated using DHCPv6 (IA-PD) for the LAN side of the user (IPoE, PPPoE). Maps to DHCPv6 option IA-PD [25] sub-option IA-Prefix [26] Prefix. An exact Delegated-prefix-Length [DPL] match with configure service ies | vprn service-id subscriber-interface ip-int-name ipv6 delegated-prefix-length [48 to 64] is required with the received attribute prefix-length unless a variable DPL is configured (configure service ies | vprn service-id subscriber-interface ip-int-name ipv6 delegated-prefix-length variable). In the latter case, multiple hosts for the same group-interface having different prefix-length [48 to 64] per host are supported. Simultaneous returned attributes [123] Delegated-IPv6-Prefix and [26.6527.131] Alc-Delegated-IPv6-Pool are handled as host setup failures. Attribute is also used in CoA and Disconnect Message (part of the ESM or AA user identification-key).

For data-triggered subscriber host authentication, an Access-Accept message can include this attribute to specify the prefix to create an IPv6 prefix host.

26.2352.1

Client-DNS-Pri

The IPv4 address of the primary DNS server for this subscriber’s connection and maps to PPPoE IPCP option 129 Primary DNS Server address or DHCPv4 option 6 Domain Server. This attribute is an alternative for 26.4874.4 ERX-Primary-Dns or 26.6527.9 Alc-Primary-Dns.

26.2352.2

Client-DNS-Sec

A IPv4 address of the secondary DNS server for this subscriber’s connection and maps to 'PPPoE IPCP option 131 Secondary DNS Server address or DHCPv4 option 6 Domain Server. This attribute is an alternative for 26.4874.5 ERX-Secondary-Dns or 26.6527.10 Alc-Secondary-Dns.

26.2352.36

Ip-Address-Pool-Name

The name of an assigned address pool that should be used to assign an address for the user and maps to DHCPv4 option [82] vendor-specific-option [9] sub-option [13] dhcpPool if option is enabled on the node (configure service ies | vprn service-id subscriber-interface ip-int-name group-interface ip-int-name dhcp option vendor-specific-option pool-name). Alternative to [88] Pool-Name and [26.4874.2] ERX-Address-Pool-Name. Pool names longer than the allowed maximum are treated as host setup failures. [8] Framed-IP-Address attribute with value different from 255.255.255.254 has precedence over [26.2352.36] Ip-Address-Pool-Name when both are present in RADIUS Access-Accept.

26.2352.99

RB-Client-NBNS-Pri

The IPv4 address of the primary NetBios Name Server (NBNS) for this subscriber’s connection and maps to PPPoE IPCP option 130 Primary NBMS Server address or DHCPv4 option44 NETBIOS name server. This attribute is an alternative for 26.4874.6 ERX-Primary-Wins or 26.6527.29 Alc-Primary-Nbns.

26.2352.100

RB-Client-NBNS-Sec

The IPv4 address of the secondary NetBios Name Server (NBNS) for this subscriber’s connection and maps to PPPoE IPCP option 132 Secondary NBMS Server address or DHCPv4 option44 NETBIOS name server. This attribute is an alternative for 26.4874.7 ERX-Secondary-Wins or 26.6527.30 Alc-Secondary-Nbns.

26.3561.1

Agent-Circuit-Id

Information describing the subscriber agent circuit identifier corresponding to the logical access loop port of the Access Node or DSLAM from which a subscriber's requests are initiated. Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute circuit-id.

For data-triggered subscriber host authentication:

• in Access-Request, the attribute contains the source IPv4 or IPv6 address of the data trigger packet

• when included in Access-Accept, the attribute is used as circuit-id to build the IPoE session key when configure subscriber-mgmt ipoe-session-policy policy-name circuit-id-from-auth is configured

For data-triggered subscriber host authentication, this attribute in the Access-Request message contains the source IPv4 or IPv6 address of the data-trigger. The Access-Accept message can include this attribute to specify the circuit ID of the IPoE session if the configure subscriber-management ipoe-session-policy name circuit-id-from-auth command is configured.

26.3561.2

Agent-Remote-Id

An operator-specific, statically configured string that uniquely identifies the subscriber on the associated access loop of the Access Node or DSLAM. Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute remote-id.

26.3561.129

[26.6527.133] Alc-Access-Loop-Encap-Offset when returned in Access-Accept is taken into account (overrules received tags and preconfigured encapsulation types) for ALE adjust (last mile aware shaping) but is not reflected in access-loop-options send to RADIUS. Alc-Access-Loop-Encap from ANCP are currently not taken into account for ALE adjust.

26.3561.254

Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute access-loop-options.

26.4874.2

ERX-Address-Pool-Name

The name of an assigned address pool that should be used to assign an address for the user and maps to dhcpv4 option[82] vendor-specific-option [9] sub-option [13] dhcpPool if option is enabled on the node (configure service ies | vprn service-id subscriber-interface ip-int-name group-interface ip-int-name dhcp option vendor-specific-option pool-name). Alternative to [88] Pool-Name and [26.2352.36] Ip-Address-Pool-Name. Pool names longer than the allowed maximum are treated as host setup failures. [8] Framed-IP-Address attribute with value different from 255.255.255.254 has precedence over [26.4874.2] ERX-Address-Pool-Name when both are present in RADIUS Access-Accept.

26.6527.11

Alc-Subsc-ID-Str

A subscriber is a collection of subscriber-hosts (typically represented by IP-MAC combination) and is uniquely identified by a subscriber string. Subscriber-hosts queues or policers belonging to the same subscriber (residing on the same forwarding complex) can be treated under one aggregate scheduling QoS mechanism. Fallback to preconfigured values if attribute is omitted. Attribute values longer than the allowed string value are treated as setup failures. Can be used as key in CoA and Disconnect Message.

26.6527.12

Alc-Subsc-Prof-Str

The subscriber profile is a template that contains settings (accounting, IGMP, HQoS, and so on) that apply to all hosts belonging to the same subscriber where [26.6527.12] Alc-Subsc-Prof-Str is the string that maps (configure subscriber-mgmt sub-ident-policy sub-ident-policy-name sub-profile-map) to such an subscriber profile (configure subscriber-mgmt sub-profile subscriber-profile-name). Strings longer than the allowed maximum are treated as setup failures. Unreferenced strings (where the string does not map to a policy) are silently ignored and a fallback to preconfigured defaults is done.

26.6527.13

Alc-SLA-Prof-Str

The SLA profile is a template which contains settings (filter, QoS, host-limit, and so on) which are applicable to individual hosts were [26.6527.13] Alc-SLA-Prof-Str is the string that maps (configure subscriber-mgmt sub-ident-policy sub-ident-policy-name sla-profile-map) to such a sla profile (configure subscriber-mgmt sla-profile sla-profile-name). Strings longer than the allowed maximum are treated as setup failures. Unreferenced strings (where the string does not map to a policy) are silently ignored and a fallback to preconfigured defaults is done.

26.6527.16

Alc-ANCP-Str

Information describing the subscriber agent circuit identifier corresponding to the logical access loop port of the Access Node or DSLAM from which a subscriber's requests are initiated and used to associate the ANCP Circuit-Id (info received using ANCP Port Up and Port Down) with the PPPoE/IPoE Circuit-Id (info received using [26.6527.16] Alc-ANCP-Str and [26.3561.1] Agent-Circuit-Id). A subscriber is associated with ANCP when both strings are equal. For associated subscribers, the ingress and egress ANCP QoS rules apply (configure subscriber-mgmt ancp ancp-policy policy-name and configure subscriber-mgmt sub-profile ancp ancp-policy policy-name.

26.6527.18

Alc-Default-Router

Maps to an DHCP offer or ACK message option [3] default-router for a DHCPv4 RADIUS proxy scenario and defines the default gateway for the user. This attribute is silently ignored if the NAS is using DHCPv4 relay. In the latter case, the default-router is part of the DHCPv4 server configuration.

26.6527.27

Alc-Client-Hardware-Addr

MAC address from a user that requests a service and included in Authentication (configure subscriber-mgmt authentication-policy name include-radius-attribute mac-address). May be included in CoA as host identification attribute.

26.6527.28

Alc-Int-Dest-Id-Str

A string representing an aggregation point (example, Access Node) and interpreted as the intermediate destination ID. Subscribers connected to the same aggregation point receives the same int-dest-id string assigned. The int-dest-id is used in MC ring access redundancy to identify subscribers behind a ring node (configure redundancy multi-chassis peer ip-address mc-ring ring/l3-ring name ring-node ring-node-name). The int-dest-id can be used in QoS to shape the egress traffic of a group of subscribers to an aggregate rate using Vports (configure port port-id ethernet access egress vport name host-match dest destination-string). For egress policed subscriber traffic, the int-dest-id can be used to select the egress queue-group for forwarding (configure port port-id ethernet access egress queue-group name host-match dest destination-string). Strings longer than the allowed maximum are treated as setup failures.

26.6527.29

Alc-Primary-Nbns

The IPv4 address of the primary NetBios Name Server (NBNS) for this subscriber’s connection and maps to PPPoE IPCP option 130 Primary NBMS Server address or DHCPv4 option44 NETBIOS name server. This attribute is an alternative for 26.2352.99 RB-Client-NBNS-Pri or 26.4874.6 ERX-Primary-Wins.

26.6527.30

Alc-Secondary-Nbns

26.6527.34

Alc-PPPoE-PADO-Delay

Specifies the number in deciseconds that the PPPoE protocol stack on the NAS waits before sending a PADO packet in response to a PADI request. In dual homed topologies, you may want to designate a primary NAS and a backup NAS for handling a particular service request. In such a scenario, you can configure a delay for the backup NAS to allow sufficient time for the primary NAS to respond to the client with a PADO packet. If the primary NAS does not send the PADO packet within this delay period, then the backup NAS sends the PADO packet after the delay period expires. This attribute is only applicable if RADIUS PADI authentication is used (configure subscriber-mgmt authentication-policy name pppoe-access-method padi). Values above the allowed Limits are truncated at the Limits boundary. There is no PADO delay if the attribute is omitted or if the attribute is received with a value of zero.

26.6527.35

Alc-PPPoE-Service-Name

Maps to PADI field PPPoE tags [0x0101] service-name and is sent in the Access-Request if enabled under configure subscriber-mgmt authentication-policy name include-radius-attribute pppoe-service-name. A PPPoE-Service-Name above the allowed maximum length is handled as a PPPoE session setup failure.

26.6527.36

Alc-DHCP-Vendor-Class-Id

Initiated by DHCP clients using option [60] Vendor Class Identifier and reflected in Authentication. (configure subscriber-mgmt authentication-policy name include-radius-attribute dhcp-vendor-class-id or configure aaa isa-radius-policy name auth-include-attributes dhcp-vendor-class-id). DHCP option [60] Vendor Class Identifier can also be used as username in RADIUS requests. (configure subscriber-mgmt authentication-policy name user-name-format dhcp-client-vendor-opts).

26.6527.45

Alc-App-Prof-Str

Application Assurance for residential, business, or transit-AA subscribers is enabled through the assignment of an application profile as part of either enhanced subscriber management or static configuration. [26.6527.45] Alc-App-Prof-Str is a string that maps (configure subscriber-mgmt sub-ident-policy sub-ident-policy-name app-profile-map) to such an application profile (configure application-assurance group aa-group-id:partition-id policy app-profile app-profile-name). This attribute is used in access-accept to assign an application profile during esm host creation and in CoA to change the application profile of a AA-subscriber or to create transit AA-subscriber. Strings longer than the allowed maximum are treated as setup failures. Unreferenced strings (strings not mapping to an application profile) silently triggers a fallback to preconfigured default values if allowed. If no default value is preconfigured, the subscriber's application profile is silently disabled for esm AA-subscriber; in case of a transit AA-subscriber creation, the CoA is rejected. The change of an application profile to one configured under a different group or partition or the modification of the application profile of a static AA-subscriber is not allowed and is treated as setup failures.

26.6527.99

Alc-Ipv6-Address

The IPv6 address to be configured to the WAN side of the user (IPoE,PPPoE) using DHCPv6 (IA-NA). Maps to DHCPv6 option IA-NA[3] sub-option IA-Address[5] address. This attribute is an alternative to [97] Framed-IPv6-Prefix and [100] Framed-IPv6-Pool, which also assigns IPv6 addressing to the wan-side of a host using SLAAC or DHCPv6 IA-NA. Attribute is also used in CoA and Disconnect Message (part of the ESM or AA user identification-key).

For data-triggered subscriber host creation in the Enhanced Subscriber Management (ESM) context, the attribute can be included in an Access-Accept message to specify the IPv6 address to create a /128 IPv6 host.

For data-triggered authentication of an IPv6 UE in Distributed Subscriber Management (DSM) context, this attribute contains the IPv6 address that triggered the request. Inclusion of this attribute is configured under configure aaa isa-radius-policy policy-name auth-include-attributes ipv6-address.

For data-triggered subscriber host creation, an Access-Accept message can contain this attribute to specify the IPv6 address to create an IPv6 /128 host.

26.6527.100

Alc-Serv-Id

Applies to FWA sessions only.

This VSA refers to the service where the GTP sessions are terminated (configure service {vprn | ies} service-id). This overrides a potential default configured under configure subscriber-mgmt gtp apn-policy policy-name apn apn defaults group-interface interface-name svc-id service-id. This VSA must be accompanied with a valid Alc-Interface VSA.

26.6527.101

Alc-Interface

Applies to FWA sessions only.

This VSA refers to a group-interface of type gtp where the GTP sessions are terminated (configure service {vprn | ies} subscriber-interface ip-int-name group-interface ip-int-name gtp). This overrides a potential default configured under configure subscriber-mgmt gtp apn-policy policy-name apn apn defaults group-interface interface-name svc-id service-id. If neither a default nor a radius-specified interface is provided, session setup fails.

26.6527.102

Alc-ToServer-Dhcp-Options

Send to RADIUS all DHCPv4 options received in a DHCPv4 message triggering authentication. The DHCPv4 options are concatenated in the attribute up to maximum length per attribute. If more space is needed, an additional attribute is included. If the total dhcp options space requires more than the total maximum length, then no attributes are included. Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute dhcp-options.

This feature is supported for both DHCP relay and proxy.

For DHCP triggered authentication in a Distribute Subscriber Management (DSM) context, this attribute contains the DHCP client options as sent to the WLAN-GW. Inclusion of this attribute is configured using configure aaa isa-radius-policy name auth-include-attributes dhcp-options.

26.6527.103

Alc-ToClient-Dhcp-Options

The value of this attribute represents DHCPv4 options encoded in a hexadecimal format. DHCPv4 options originated by RADIUS are appended to the options already present in the DHCPv4 messages toward the client. Multiple DHCP options can be concatenated in a single VSA.

Attributes outside the defined limits result in a setup failure. When more than the supported number of attributes are received from RADIUS, only the supported number of VSAs are appended in the DHCP message, starting with the first attribute received. The remaining attributes are silently ignored.

26.6527.105

Alc-Ipv6-Primary-Dns

The IPv6 address of the primary DNSv6 server for this subscriber’s connection. Maps to DNS Recursive Name Server option 23 (RFC 3646) in DHCPv6 and Recursive DNS Server Option type 25 (RFC 6106) for SLAAC RA. This attribute is an alternative for [26.4874.47] ERX-Ipv6-Primary-Dns.

26.6527.106

Alc-Ipv6-Secondary-Dns

The IPv6 address of the secondary DNSv6 server for this subscriber’s connection. Maps to DNS Recursive Name Server option 23 (RFC 3646) in DHCPv6 and Recursive DNS Server Option type 25 (RFC 6106) for SLAAC RA. This attribute is an alternative for [26.4874.48] ERX- Ipv6-Secondary-Dns.

26.6527.126

Alc-Subscriber-QoS-Override

Used to override queue or policer parameters (CIR, PIR, CBS, MBS) and HQoS parameters (aggregate rate, scheduler rate or root arbiter rate) configured at sla-profile and sub-profile context. Enables per subscriber or host customization. Each set of Alc-Subscriber-QoS-Override attributes in a RADIUS message replaces the set of Alc-Subscriber-QoS-Override attributes from a previous message. Hence the SLA profile or subscriber profile QoS configuration is always used as the base config. To undo a previously enabled RADIUS QoS-override and return to the base config, send a CoA with at least one Alc-Subscriber-QoS-Override attribute. The value part of each Alc-Subscriber-QoS-Override attribute must be empty (for example, Alc-Subscriber-QoS-Override += i:q:2:). Incorrectly formatted attributes or too many attributes are treated as a setup failure or result in a CoA NAK.

26.6527.131

Alc-Delegated-IPv6-Pool

The name of an assigned pool that should be used to assign an IPv6 prefix using DHCPv6(IA-PD) to the LAN side of the user (IPoE, PPPoE). Maps to DHCPv6 vendor-option[17],sub-option[2] pfx-pool. Alc-Delegated-ipv6-pool names longer than the allowed maximum are treated as host setup failures. Alternative method for [123] Delegated-IPv6-Prefix so simultaneous returned attributes [123] Delegated-IPv6-Prefix and [26.6527.131] Alc-Delegated-IPv6-Pool are handled as host setup failures. The length information [DPL] can be supplied using [26.6527.161] Alc-Delegated-IPv6-Prefix-Length along with the pool name. The [26.6527.161] Alc-Delegated-IPv6-Prefix-Length has priority over other possible sources of DPL. (As a fixed [48 to 64] DPL or variable DPL under configure service ies | vprn service-id subscriber-interface ipv6 delegated-prefix-length or on the dhcpv6 server configure router dhcp6 local-dhcp-server server-name pool pool-name delegated-prefix-length).

26.6527.132

Alc-Access-Loop-Rate-Down

The actual downstream rate (coded in kb/s) of a PPPoE subscriber's synchronized DSL link and competes with the value received from alternative sources (dsl-forum tags, LUDB, ANCP). Values outside the limits are treated as setup failures. This attribute is silently ignored for non-MLPPP sessions or IPoE sessions.

26.6527.133

Alc-Access-Loop-Encap-Offset

The last mile encapsulation representing the subscriber’s DSL access loop encapsulation. When returned in RADIUS-Accept (PTA or LAC), it is taken into account for ALE adjust (last mile aware shaping) but not reflected in [26.3561.144] Access-Loop-Encapsulation (access-loop-options) send to Accounting. For LAC, this attributes maps to LTP AVP [3561-144] Access-Loop-Encapsulation.

26.6527.135

Alc-PPP-Force-IPv6CP

Forces IPv6CP negotiation in conditions where no IPv6 related attributes (such as v6 pool, v6 prefix, v6 address, DNSv6) are obtained using authentication (Access Accept, local user database, and so on). Without these IPv6 related attributes, the NAS cannot detect that this is a dual-stack PPPoE user and therefore it does not start IPv6CP negotiation.

An attribute value other than 0 (zero) forces IPv6CP negotiation to start when no IPv6 attributes are obtained in authentication.

An attribute value of 0 (zero) is treated the same as not sending the attribute.

26.6527.136

Alc-Onetime-Http-Redirection-Filter-Id

The preconfigured IPv4 filter with HTTP redirection rules. using this host- specific filter only the first HTTP request from the host is redirected to a configured URL with specified parameters. There is no HTTP redirection for subsequent HTTP requests which is useful in cases where service providers need to push a web page of advertisement or announcements to broadband users.

26.6527.146

Alc-Wlan-APN-Name

This VSA contains the Access Point Name string as signaled in the incoming GTP-C message for FWA sessions.

To include this attribute use the command configure subscriber-mgmt authentication-policy name include-radius-attribute apn.

26.6527.147

Alc-MsIsdn

This VSA contains the MSISDN (telephone number) as signaled in the incoming GTP-C message for FWA sessions. If the corresponding GTP-C IE is not present the VSA is not included.

Inclusion of this attribute can be configured using configure subscriber-mgmt authentication-policy name include-radius-attribute msisdn.

26.6527.160

Alc-Relative-Session-Timeout

Sets or resets the IPoE or PPPoE session timeout to a relative value (current session time + newly received Alc-Relative-Session-Timeout). Attribute equals to [27] Session-Timeout if received in Access-Accept since the current session time equals zero. A value of zero sets or resets the session-timeout to infinite (no session-timeout). Simultaneous received [27] Session-Timeout and [26.6527.160] Alc-Relative-Session-Timeout are treated as a setup failure (setup failure if received in Access-Accept or CoA rejected (NAK) with error cause = Invalid Request).

26.6527.161

Alc-Delegated-IPv6-Prefix-Length

Defines the IA-PD length information [DPL] and only applicable together with [26.6527.131] Alc-Delegated-IPv6-Pool (silently ignored if received in RADIUS Accept without Alc-Delegated-IPv6-Pool). Maps to DHCPv6 vendor-option[17], sub-option[3] pfx-len. The [26.6527.161] Alc-Delegated-IPv6-Prefix-Length has priority over other possible sources of DPL. (As a fixed [48 to 64] DPL or variable DPL under configure service ies |vprn service-id subscriber-interface ip-int-name ipv6 delegated-prefix-length or on the dhcpv6 server configure router dhcp6 local-dhcp-server server-name pool pool-name delegated-prefix-length). DPL values outside the limits are treated as setup failures.

26.6527.174

Alc-Lease-Time

Defines the lease-time in seconds for RADIUS proxy and create-host-CoA scenarios only. The [27] Session-Timeout is interpreted and used as IPoE lease-time if [26.6527.174] Alc-lease-Time is omitted. Returning attribute [26.6527.174] Alc-Lease-Time in other scenarios than radius-proxy and create-host-CoA are treated as setup failures.

26.6527.175

Alc-DSL-Line-State

Status of the DSL line obtained using ANCP can be one of three value: SHOWTIME (the modem is ready to transfer data), IDLE (line is idle) or SILENT (line is silent). Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute access-loop-options.

26.6527.176

Alc-DSL-Type

Type of the DSL line (ADSL1, ADSL2, ADSL2PLUS, VDSL1, VDSL2, SDSL, other) obtained using ANCP.

This attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute access-loop-options.

26.6527.177

Alc-Portal-Url

The URL to which traffic matching the host’s IPv4 filter entry with HTTP redirect action is redirected. The URL overrides the configured URL in the redirect filter. RADIUS overrides must explicitly be enabled: configure filter ip-filter filter-id entry entry-id action http-redirect rdr-url-string allow-radius-override.

26.6527.178

Alc-Ipv6-Portal-Url

The URL to which traffic matching the host’s IPv6 filter entry with HTTP redirect action is redirected. The URL overrides the configured URL in the redirect filter. RADIUS overrides must explicitly be enabled: configure filter ipv6-filter filter-id entry entry-id action http-redirect rdr-url-string allow-radius-override.

26.6527.180

Alc-SAP-Session-Index

Per SAP, this is a unique PPPoE or IPoE session index that can be included in RADIUS Access Request messages. The lowest free index is assigned to a new PPPoE or IPoE session. Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute sap-session-index.

26.6527.181

Alc-SLAAC-IPv6-Pool

A pool name that can be used in local address assignment to assign an IPv6 SLAAC prefix using a Router Advertisement to the WAN side of the IPoE or PPPoE user.

Alc-SLAAC-IPv6-Pool names longer than the allowed maximum are treated as host setup failures. If local-address-assignment is not enabled on the group-interface for ipv6 client-application ppp-slaac, then the PPP session is terminated. If local-address-assignment is not enabled on the group-interface for ipv6 client-application ipoe-slaac, then the IPoE host is not instantiated.

26.6527.183

Alc-WPP-Error-Code

This attribute specifies the value of the ErrCode that the system should use in a WPP ACK_AUTH packet. This attribute can only be included in a RADIUS Access-Reject packet.

26.6527.185

Alc-Onetime-Http-Redirect-Reactivate

An indication to reactivate a onetime HTTP redirect filter for the host.

When received in a RADIUS CoA message, the filter with the value indicated by [26.6527.136] Alc-Onetime-Http-Redirection-Filter-Id is activated.

If [26.6527.136] Alc-Onetime-Http-Redirection-Filter-Id contains the value 0, then the existing onetime http redirect filter ID associated with the host is removed.

If no [26.6527.136] Alc-Onetime-Http-Redirection-Filter-Id VSA is provided in the RADIUS CoA message, then the existing onetime http redirect filter ID associated with the host is applied.

The value of the [26.6527.185] Alc-Onetime-Http-Redirect-Reactivate VSA is opaque. It is the presence of the VSA in a RADIUS CoA that triggers the action.

26.6527.191

Alc-ToServer-Dhcp6-Options

This attribute contains DHCPv6 client options present in a DHCPv6 Solicit or Request message to be passed to RADIUS in an Access-Request. Multiple attributes are inserted when the length of the DHCPv6 options exceeds the maximum length of a single attribute. No attributes are included if the total length of the DHCPv6 options exceeds the total limit for this attribute.

When the DHCPv6 solicit or request message is encapsulated in a Relay-Forward message, only the inner DHCPv6 client options are copied in the Alc-ToServer-Dhcp6-Options attribute. Options inserted by a Relay Agent are ignored.

Attribute is included or excluded based on configure subscriber-mgmt authentication-policy name include-radius-attribute dhcp6-options. This feature is supported for both DHCP relay and proxy.

For DHCPv6 triggered authentication in a Distribute Subscriber Management (DSM) context, this attribute contains the DHCPv6 client options as sent to the WLAN-GW. Inclusion of this attribute is configured using configure aaa isa-radius-policy policy-name auth-include-attributes dhcp6-options.

26.6527.192

Alc-ToClient-Dhcp6-Options

The value of this attribute represents DHCPv6 options encoded in a hexadecimal format. DHCPv6 options originated by RADIUS are appended to the options already present in the DHCPv6 Advertise and Reply messages toward the client.

Attributes outside the defined limits result in a setup failure. When more than the supported number of attributes are received from RADIUS, only the supported number of VSAs are appended in the DHCP message, starting with the first attribute received. The remaining attributes are silently ignored.

This feature is supported for both DHCP relay and proxy.

26.6527.200

Alc-v6-Preferred-Lifetime

An IPv6 address or prefix preferred lifetime is the length of time that a valid address or prefix is preferred (for example, the time until deprecation). When the preferred lifetime expires, the address or prefix becomes deprecated (it can still be used in existing communications but should not be used as a source in new communications).

This attribute is applicable only when an IPv6 address or prefix is assigned using RADIUS (DHCPv6 proxy). It overrides the dhcp6 proxy-server preferred-lifetime configuration on the group-interface.

The attribute value is expressed in seconds. Values outside the allowed range result in a setup failure.

If, for the final determined values from the different sources (LUDB, RADIUS, defaults), the following rule is violated:

renew timer 7705 SAR-8 rebind timer <= preferred lifetime <= valid lifetime

then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min, preferred-lifetime = 1hr, valid-lifetime = 1 day.

Note that only a single value can be specified that applies to both IA-NA address and IA-PD prefix.

26.6527.201

Alc-v6-Valid-Lifetime

The IPv6 address or prefix valid lifetime is the length of time an address or prefix remains in the valid state (for example, the time until invalidation). When the valid lifetime expires, the address or prefix becomes invalid and must no longer be used in communications. This attribute is used as the DHCPv6 lease time.

This attribute is applicable only when an IPv6 address or prefix is assigned using RADIUS (DHCPv6 proxy). Overrides the dhcp6 proxy-server valid-lifetime configuration on the group-interface.

The attribute value is expressed in seconds. Values outside the allowed range result in a setup failure.

If, for the final determined values from the different sources (LUDB, RADIUS, defaults), the following rule is violated:

renew timer <= rebind timer <= preferred lifetime <= valid lifetime

then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min, preferred-lifetime = 1hr, valid-lifetime = 1 day.

Note that only a single value can be specified that applies to both IA-NA address and IA-PD prefix.

26.6527.202

Alc-Dhcp6-Renew-Time

The attribute value represents the DHCPv6 lease renew time (T1). T1 is the time at which the client contacts the addressing authority to extend the lifetimes of the DHCPv6 leases (addresses or prefixes).

This attribute is applicable only when an IPv6 address or prefix is assigned using RADIUS (DHCPv6 proxy). Overrides the dhcp6 proxy-server renew-timer configuration on the group interface.

The attribute value is expressed in seconds. Values outside the allowed range result in a setup failure.

If, for the final determined values from the different sources (LUDB, RADIUS, defaults), the following rule is violated:

renew timer <= rebind timer <= preferred lifetime <= valid lifetime

then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min, preferred-lifetime = 1hr, valid-lifetime = 1 day.

Note that only a single value can be specified that applies to both IA-NA address and IA-PD prefix.

26.6527.203

Alc-Dhcp6-Rebind-Time

The attribute value represents the DHCPv6 lease rebind time (T2). T2 is the time at which the client contacts any available addressing authority to extend the lifetimes of DHCPv6 leases.

This attribute is applicable only when an IPv6 address or prefix is assigned using RADIUS (DHCPv6 proxy). The attribute overrides the dhcp6 proxy-server rebind-timer configuration on the group interface

The attribute value is expressed in seconds. Values outside the allowed range result in a setup failure.

If, for the final determined values from the different sources (LUDB, RADIUS, defaults), the following rule is violated:

renew timer <= rebind timer <= preferred lifetime <= valid lifetime

then the default timers are used: renew-timer = 30 min, rebind-timer = 48 min, preferred-lifetime = 1hr, valid-lifetime = 1 day.

Note that only a single value can be specified that applies to both IA-NA address and IA-PD prefix.

26.6527.217

Alc-UPnP-Sub-Override-Policy

Specifies the UPnP policy to use for this L2-Aware subscriber. The policy must be configured in configure service upnp upnp-policy policy-name.

Overrides the configured policy in the sub-profile for the subscriber: configure subscriber-mgmt sub-profile name upnp-policy policy-name.

The value ‟_tmnx_no_override” removes any existing override and installs the upnp-policy configured in the sub-profile instead.

The value ‟_tmnx_disabled” creates a special override that disables UPnP for this subscriber.

Specifying a non-existing policy results in a host or session setup failure or in a CoA Reject.

All hosts belonging to the subscriber are affected by a UPnP policy override.

Changing the UPnP policy clears all existing UPnP mappings.

26.6527.228

Alc-Trigger-Acct-Interim

When included in a CoA message an accounting interim update is generated for all accounting modes that have interim-updates enabled. The Alc-Trigger-Acct-Interim attribute with free formatted string value is echoed in the CoA triggered accounting interim update message. The [26.6527.163] Alc-Acct-Triggered- Reason attribute in the interim update is set to 18 (CoA-Triggered).

26.6527.232

Alc-Acct-Interim-IvI

Tagged Attribute.

The interval in seconds at which Acct-Interim-Update messages should be generated. Overrides the local configured update-interval value in the RADIUS accounting policy. Only takes effect if interim-updates are enabled for one of the accounting modes in the RADIUS accounting policy.

With attribute value=0, the interim accounting is switched off.

The tag value (1 to 5) indicates which RADIUS accounting policy in the subscriber profile is updated.

To change the update interval of the first accounting policy, attribute [85] Acct-Interim-Interval takes precedence over [26.6527.232] Alc-Acct-Interim-Ivl with tag 1 when both are included.

26.6527.234

Alc-DNAT-Override

A composite RADIUS attribute used to modify DNAT function for L2-Aware NAT subscribers:

• enable or disable DNAT functionality without affecting SNAPT

• modify destination IP address in DNAT

After the DNAT configuration is modified using CoA (by enabling or disabling DNAT or changing the DNAT IP address), the existing flows remain active for five more seconds while the new flows are being created in accordance with the new configuration. After a five-second timeout, the stale flows are cleared from the system.

If multiple Alc-DNAT-Override attributes with conflicting actions are received in the same CoA or Access-Accept, the last one takes precedence.

26.6527.238

Alc-Remove-Override

This attribute, when included in a CoA, removes the override installed with or deactivates the action triggered by the referenced attribute ID.

26.6527.242

Alc-Radius-Py

A free format attribute reserved for use in combination with a RADIUS Python script. SR OS ignores the attribute when received in an access accept or CoA and does not generate the attribute.

The primary purpose for this attribute is to interact with RADIUS servers that do not support RFC 6929 extended and long extended vendor specific attribute types. This attribute can be used between the RADIUS server and the Python script. The Python script should convert the attribute value in an RFC 6929 compliant attribute format.

26.6527.244

Alc-Force-DHCP-Relay

This attribute is only supported for DHCP promotion of data-triggered hosts.

When this attribute is included in an Access Accept message at the authentication of a data triggered subscriber hosts IPoE session, then a DHCP relay is performed when the subscriber host in the session is promoted to a DHCP host at renew or rebind.

The IP or IPv6 address/prefix origin, or both are set to DHCP or DHCP6 for the data triggered subscriber host that is promoted to a DHCP host.

The IP address/prefix for all IP stacks of the subscribers IPoE session must also be included in the Access Accept.

Attributes with invalid value are ignored.

241.26.6527.16

Alc-IPv6-Router-Adv-Policy

This attribute specifies the Router Advertisement policy to be used for this subscriber host or session. The Router Advertisement policy is configured in configure subscriber-mgmt router-advertisement-policy name. The Router Advertisement policy overrides the default Router Advertisement parameters configured in the ipv6 router-advertisements CLI context at the group interface or subscriber interface (wholesale or retail).

Referencing a non-existing policy results in a subscriber host or session setup failure or a CoA reject.

241.26.6527.17

Alc-Nat-Outside-IPs

This attribute allows to specify an outside NAT IP address from AAA instead of allocating an address from the local NAT pools. An IP address can be provided for each policy.

241.26.6527.18

Alc-Mld-Import-Policy

This attribute overrides the subscriber’s current list of dynamic MLD import policies. The order in which the policies were added can be checked with show router [router-instance] mld hosts host ipv6-address detail. Note that the configured MLD import policy (configure subscriber-mgmt mld-policy mld-policy-name import policy-name) cannot be overridden and is always applied as the last policy in the MLD import policies list. As the import policies are evaluated in the applied order using a match and exit, it is good practice to only include a default-action in the configured MLD import policy.

Access-Accept fails and CoA is rejected if more than 14 attributes are present.

241.26.6527.19

Alc-Bonding-Id

Attribute description is defined in the Bonding section, see Bonding (description).

241.26.6527.22

Alc-Bonding-Reference-Rate

Attribute description is defined in the Bonding section, see Bonding (description).

241.26.6527.27

Alc-IPv6-Sub-If-Prefix

This attribute installs a subscriber interface IPv6 prefix of type pd, wan-host or both. This is similar to a statically configured IPv6 prefix on a subscriber interface. The prefix is part of the subscriber host or session state. The prefix is removed from the system when the subscriber host or session disconnects. An invalid prefix, such as when overlapping with a static provisioned prefix, results in a subscriber host or session setup failure.

241.26.6527.35

Alc-Mld-Import-Policy-Modif

This attribute modifies the subscriber’s dynamic MLD import policy list. The command can either add or delete an MLD import policy to or from the list.

The CoA is rejected if more than the allowed number of attributes are included or if the number of resulting dynamic MLD import policies is more than 14.

241.26.6527.37

Alc-VAS-IPv4-Filter

(l2-aware NAT subscriber only).

This VSA enables IPv4 service chaining for an l2-aware NAT subscriber using the named Value Added Services (VAS) filter configured under configure subscriber-mgmt isa-service-chaining vas-filter.

241.26.6527.38

Alc-VAS-NSH-IPv4-Opaque-Meta-Data

(l2-aware NAT subscriber only).

For Value Added Services (VAS) enabled sessions this VSA specifies the Network Services Header (NSH) context header data for MD type 1. This value overrides insert-subscriber-id or opaque-data configured under configure subscriber-mgmt isa-service-chaining vas-filter filter-name entry id action {downstream | upstream} insert-nsh meta-data. An NSH header with this context data is only inserted if svc-path is correctly configured under configure subscriber-mgmt isa-service-chaining vas-filter filter-name entry id action {downstream | upstream} insert-nsh.

241.26.6527.39

Alc-Static-Port-Forward

Static port forwards to be installed for layer-2 aware NAT subscribers using external address assignment.

241.26.6527.40

Alc-IPv6-Slaac-Replacement-Prefix

Override the current host SLAAC prefix with the one specified in the VSA. The host address origin is not changed. Three subsequent Router Advertisements are sent to the SLAAC host respecting the configured advertisement intervals. The Router Advertisements contain both the current and new SLAAC prefixes: the valid and preferred lifetime for the current prefix are set to zero and for the new prefix the values are either specified in the router advertisement policy or the group interface configuration. Because of the prefix change, all traffic send using the old SLAAC prefix as source address is dropped in the BNG when anti-spoof is set to IP + MAC.

Note that the prefix change results in a SLAAC host delete and create.

241.26.6527.47

Alc-SPI-Sharing-Id

Sets or overrides the SLA Profile Instance (SPI) sharing method for this subscriber session to SPI sharing per group or to the default SPI sharing method (per SAP or per session) as specified in the SLA profile (configure subscriber-mgmt sla-profile sla-profile-name def-instance-sharing spi-sharing-type).

For SPI sharing per group, the group is identified with an integer group identifier (for example, the SPI sharing ID). An SPI is shared by all subscriber sessions with the same subscriber ID, SAP, SLA profile and group ID.

Setting this attribute for an IPoE host with IPoE session disabled on the group interface results in a setup failure.

Unsupported values result in a subscriber session setup failure.

241.26.6527.57

Alc-Gtp-Skip-Ipv4-Alloc-Override

3GPP describes the following address management related Protocol Configuration Option (PCO) values.

• 000AH (IP address allocation using NAS signaling)

  An IPv4 address is returned in create-session-response (also known as non-deferred address allocation).

• 000BH (IPv4 address allocation using DHCPv4)

  The IPv4 address 0.0.0.0 is returned in create-session-response because DHCPoGTP follows (also known as deferred address allocation).

The FWA-GW honors the PCO Address Management options set by the RG or UE which results in a non-deferred or deferred address allocation. By default, non-deferred address allocation applies when the PCO Address Management options are not set by the RG or UE.

The default non-deferred behavior can be overruled to deferred address allocation using the following APN scope parameter: configure subscriber-mgmt gtp apn-policy policy-name apn apn skip-gtp-ipv4-alloc

The CLI parameter skip-gtp-ipv4-alloc is only applicable when PCO Address Management options are not set by the RG or UE. The skip-gtp-ipv4-alloc behavior (deferred address allocation) can be overridden to non-deferred address allocation for an individual session using the Alc-Gtp-Skip-Ipv4-Alloc-Override attribute with value 1 (on).

The Alc-Gtp-Skip-Ipv4-Alloc-Override attribute is silently ignored when the CLI parameter skip-gtp-ipv4-alloc is not configured.

241.26.6527.58

Alc-Change-Reporting-Action

Applies to FWA sessions only.

Controls the change reporting action signaled in GTP. Overrides the value specified under configure subscriber-mgmt gtp peer-profile name change-reporting-action. The specified action only applies if the MME supports change reporting.

241.26.6527.62

Alc-Host-DNAT-Override

Enables or Disables DNAT functionality on a session level. This overrides any value that has been set by the Alc-DNAT-Override attribute.

241.26.6527.71

Alc-Host-DNAT-Default-Address-Override

Overrides the DNAT destination IP address on a per session level.

This overrides both the default value configured under configure service nat nat-classifier classifier-name default-dnat-ip-address and the value set by the Alc-DNAT-Override attribute.

241.26.6527.92

Alc-PPPoE-LCP-Keepalive-Interval

Specifies the interval in seconds at which PPPoE LCP Echo-Request messages are sent. Overrides the LCP keepalive interval value configured in subscriber-mgmt ppp-policy for PPPoE PTA sessions or in the Base router or VPRN service l2tp group context for L2TP LNS sessions.

241.26.6527.93

Alc-PPPoE-LCP-Keepalive-Multiplier

Specifies the number of PPPoE Echo-Request messages that can be missed before the PPPoE session is terminated. Overrides the LCP keepalive multiplier value configured in subscriber-mgmt ppp-policy for PPPoE PTA sessions or in the Base router or VPRN service l2tp group context for L2TP LNS sessions.

245.26.6527.5

Alc-Spi-Host-And-Session-Limits

Used to override host-limits and session-limits configured at the sla-profile context. Enables to dynamically set host and session limits that are enforced per SLA Profile Instance. All subscriber hosts and sessions that belong to the same SLA Profile Instance should get the same dynamic override values.

The limits are checked at host or session creation time. When a limit is reached, the host or session creation fails.

See [245.26.6527.5] Alc-Spi-Host-And-Session-Limits attribute details for a detailed description of the attribute.

245.26.6527.6

Alc-Sub-Host-And-Session-Limits

Used to override host-limits and session-limits configured at the sub-profile context. Enables to dynamically set host and session limits that are enforced per subscriber. All subscriber hosts and sessions that belong to the same subscriber should get the same dynamic override values.

The limits are checked at host or session creation time. When a limit is reached, the host or session creation fails.

See [245.26.6527.6] Alc-Sub-Host-And-Session-Limits attribute details for a detailed description of the attribute.

nas-port <binary-spec>

<binary-spec> = <bit-specification> <binary-spec>

<bit-specification> = 0 | 1 | <bit-origin>

<bit-origin> = *<number-of-bits><origin>

<number-of-bits> = [1 to 32]

<origin> =

s: slot number

m: MDA number

p: port number, lag-id, pw-id or pxc-id

o: outer VLAN ID

i: inner VLAN ID

c: pxc-subport (a=0, b=1)

Only the lower bits of the specified origin are included if the number of bits assigned for that origin is not enough to hold its maximum value. For example, when specifying 10 bits for an outer VLAN ID (*10o), then VLAN 3000 (binary 1011 1011 1000) would be reported as 952 (binary 11 1011 1000)

The connector number of a connector port, such as c1 in port 1/2/c1/2 is not encoded in the NAS-Port attribute

For ports on an IOM-s in an SR-s chassis, such as 2/x1/1/c4/1, the MDA number is encoded as m=2 for an MDA in position x1/1 and m=3 for an MDA in position x1/2

For example:

configured nas-port

*12o*10i*3s*2m*5p for SAP 2/2/4:221.7 corresponds to the binary value 000011011101 0000000111 010 10 00100

26.6527.234

Alc-DNAT-Override

string

247 chars

{DNAT-state | DNAT-ip-addr}[,nat-policy-name]

DNAT state = none | disable

• none

  This negates any previous DNAT related override in the referenced (nat-policy-name) or default nat-policy. Consequently, the DNAT functionality is set as originally defined in the nat-policy.

• disable

  This disables DNAT functionality in the referenced (nat-policy-name) or default nat-policy.

DNAT-ip-addr = IPv4 address in dotted format (a.b.c.d)

• implicit enable with specified destination IP

DNAT-state and DNAT-ip-addr parameters are mutually exclusive

nat-policy-name = name of the nat-policy. This is an optional parameter and if not specified then the default nat-policy is assumed.

If two parameters are present simultaneously within the Alc-DNAT-Override attribute, then they are separated by a comma with no white spaces used as delimiter.

For example:

Alc-DNAT-Override=none

This re-enables DNAT functionality in the default nat-policy, assuming that DNAT was previously disabled using the Alc-DNAT-Override=disable attribute submitted either in Access-Accept or in a previous CoA. If the none value was received at the time when the DNAT is already enabled, a CoA ACK is sent back to the originator.

This negates any previous DNAT-related override in the default nat-policy. The DNAT functionality is set as originally defined in the default nat-policy. If the DNAT classifier is not present in the default nat-policy when this CoA is received, an error log message is raised.

26.6527.234

—

—

—

For example:

Alc-DNAT-Override =198.51.100.1, nat-pol-1

This changes the default DNAT IP address to 198.51.100.1 in the specified nat-policy with name nat-pol-1. DNAT is implicitly enabled in case that it was disabled before this CoA was received.

For example:

Alc-DNAT-Override = none, 198.51.100.1

DNAT-state and DNAT-ip-addr parameters are mutually exclusive within the same Alc-DNAT-Override attribute. A CoA ACK is returned to the RADIUS server and an error event is logged.

Alc-Retail-Serv-Id

The service ID of the retailer to which this subscriber host belongs. (configure service ies | vprn retail-service-id subscriber-interface retail-interface-name fwd-service wholesale-service-id fwd-subscriber-interface wholesale-interface-name). Returning an IES service ID for an IPoEv4 host is treated as a session setup failure.

This attribute must be included together with NAS-Port-Id and an IP address or prefix attribute in a CoA targeting a subscriber host in a retail service.

26.6527.31

Alc-MSAP-Serv-Id

The service ID where Managed SAPs are created. (configure service ies/vprn service-id). If this attribute is omitted, use msap defaults created under ludb or capture VPLS. (configure subscriber-mgmt local-user-db local-user-db-name ppp/ipoe host msap-defaults service service-id or configure service vpls service-id sap sap-id msap-defaults service service-id). This omitted attribute without explicitly created msap-defaults is treated as a setup failure.

26.6527.32

Alc-MSAP-Policy

Managed sap policy-name used to create managed SAPs and refers to the CLI context configure subscriber-mgmt msap-policy msap-policy-name). The policy contains similar parameters that would be configured for a regular subscriber SAP. If this attribute is omitted, then the MSAP default configured in ludb or capture-sap is used (configure subscriber-mgmt local-user-db local-user-db ppp/ipoe host host-name msap-defaults policy msap-policy-name or configure service vpls service-id sap sap-id msap-defaults policy msap-policy-name).This omitted attribute without explicitly created MSAP defaults is treated as a setup failure.

26.6527.33

Alc-MSAP-Interface

The group interface name where managed SAPs are created and refers to CLI context configure service ies | vprn service-id subscriber-interface ip-int-name group-interface ip-int-name. If this attribute is omitted, the MSAP defaults configured in the ludb or capture-sap are used. (configure subscriber-mgmt local-user-db local-user-db-name ppp/ipoe host host-name msap-defaults group-interface ip-int-name or configure service vpls service-id sap sap-id msap-defaults group-interface ip-int-name). Strings above the limits and an omitted attribute without explicitly created MSAP defaults are treated as setup failures.

241.26.6527.89

Alc-Retail-Serv-Name

The service name of the retailer to which this subscriber host belongs. (configure service ies | vprn retail-service-id name retail-service-name subscriber-interface retail-interface-name fwd-service wholesale-service-id fwd-subscriber-interface wholesale-interface-name) .

Returning an IES service name for an IPoEv4 host is treated as a session setup failure.

This attribute must be included together with NAS-Port-Id and an IP address or prefix attribute in a CoA targeting a subscriber host in a retail service.

When the host was setup from RADIUS using the Alc-Retail-Serv-Name, the CoA must also use the Alc-Retail-Serv-Name.

241.26.6527.90

Alc-MSAP-Serv-Name

The service name where managed SAPs are created. (configure service ies | vprn service-id name retail-service-name).

If this attribute is omitted, use the MSAP defaults created under ludb or capture VPLS. (configure subscriber-mgmt local-user-db local-user-db-name ppp | ipoe host msap-defaults service service-id or configure service vpls service-id sap sap-id msap-defaults service service-id). This omitted attribute without explicitly created msap-defaults is treated as a setup failure.

Tunnel-Type

The tunneling protocols to be used (in the case of a tunnel initiator) or the tunneling protocol in use (in the case of a tunnel terminator). This attribute is mandatory on LAC Access-Accept and needs to be L2TP. The same attribute is included on LNS in the Access-Request and Acct-Request if the CLI RADIUS policy include-radius-attribute tunnel-server-attrs is enabled on a 7750 SR LNS. For L2TP Tunnel or Link Accounting, this attribute is always included on LAC and LNS.

65

Tunnel-Medium-Type

The transport medium to use when creating a tunnel for those protocols (such as L2TP) that can operate over multiple transports. This attribute is mandatory on LAC Access-Accept and needs to be IP or IPv4.The same attribute is included on LNS in the Access-Request and Acct-Request if the CLI RADIUS policy include-radius-attribute tunnel-server-attrs is enabled on a 7750 SR LNS. For L2TP Tunnel or Link Accounting, this attribute is always included on LAC and LNS.

66

Tunnel-Client-Endpoint

The dotted-decimal IP address of the initiator end of the tunnel. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp local-address). If omitted in Access Accept on LAC and no local-address configured, then the address is taken from the interface with name system. This attribute is included on LNS in the Access-Request and Acct-Request only if the CLI RADIUS policy include-radius-attribute tunnel-server-attrs is enabled on a 7750 SR LNS. For L2TP Tunnel or Link Accounting, this attribute is always included on LAC and LNS as untagged.

67

Tunnel-Server-Endpoint

The dotted-decimal IP address of the server end of the tunnel is also on the LAC the destination IP for all L2TP packets for that tunnel.

To support more than 31 tunnels in a single RADIUS Access-Accept message, multiple Tunnel-Server-Endpoint attributes with the same tag can be inserted. All tunnels specified by Tunnel-Sever-Endpoint attributes with a tag uses the tunnel parameters specified by the other Tunnel attributes having the same tag value.

69

Tunnel-Password

A shared, salt-encrypted secret used for tunnel authentication and AVP-hiding. The usage of tunnel-authentication is indicated by attribute [26.6527.97] Alc-Tunnel-Challenge and the usage of AVP-hiding is indicated by attribute [26.6527.54] Alc-Tunnel-AVP-Hiding. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp password). There is no default password. Received passwords longer than the maximum character limit are truncated at that limit.

81

Tunnel-Private-Group-ID

The group ID for a particular tunneled session. This RADIUS attribute is copied by a 7750 SR LAC in AVP 37 - Private Group ID (ICCN) and is used by the LAC to indicate that this call is to be associated with a particular customer group. The 7750 SR LNS ignores AVP 37 when received from LAC. The value with tag 0 is used as default for the tunnels where the value is not specified. String lengths above the maximum value are treated as setup failures.

82

Tunnel-Assignment-ID

Indicates to the tunnel initiator the particular tunnel to which a session is to be assigned. Some tunneling protocols, such as PPTP and L2TP, allow for sessions between the same two tunnel endpoints to be multiplexed over the same tunnel, and also for a specific session to use its own dedicated tunnel. Tag-0 Tunnel-Assignment-ID:0 string, has a special meaning and the string becomes the tunnel group name that can hold up to maximum 31 tunnels with the name Tunnel-Assignment-ID-[1 to 31] string. A tunnel group with the name default_radius_group is created on the LAC when this attribute with tag-0 is omitted. This attribute is not the same as attribute [26.4874.64] ERX-Tunnel-Group or [26.6527.46] Alc-Tunnel-Group because these attributes both reference a tunnel group name created in CLI context. When not specified, the default value for Tunnel-Assignment-ID-[1 to 31] string is unnamed. String lengths above the limits are treated as a setup failure.

83

Tunnel-Preference

Indicates the relative preference assigned to each tunnel if more than one set of tunneling attributes is returned by the RADIUS server to the tunnel initiator. 0x0 (zero) being the lowest and 0x0FFFFFF(16777215) being the highest numerical value. The tunnel having the numerically lowest value in the Value field of this Attribute is assigned the highest preference. Other tunnel selection criteria are used if preference values from different tunnels are equal. Preference 50 is used when attribute is omitted. Values above the Limits wrap around by Freeradius before send to the NAS (start again from zero until the Limits).

90

Tunnel-Client-Auth-ID

Used during the authentication phase of tunnel establishment and copied by the LAC in L2TP SCCRQ AVP 7 Host Name. Reported in L2TP Tunnel or Link accounting when length is different from zero. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when the attribute is omitted (configure router/service vprn service-id l2tp local-name). The Node system-name is copied in AVP Host Name if this attribute is omitted and no local-name is configured.

91

Tunnel-Server-Auth-ID

Used during the authentication phase of tunnel establishment and reported in L2TP Tunnel or Link accounting when length is different from zero. For authentication the value of this attribute is compared with the value of AVP 7 Host Name from the received LNS SCCRP. Authentication from LAC point of view passes if both attributes are the same. This authentication check is not performed if the RADIUS attribute is omitted.

26.2352.21

Tunnel-Max-sessions

The maximum number of sessions allowed per tunnel group (untagged attribute only). This attribute has the same function as attribute 26.6527.48 Alc-Tunnel-Max-Sessions:0. No sessions are setup above the limits. Preconfigured values configure router/service vprn service-id l2tp session-limit are used when attribute is omitted.

26.4874.33

ERX-Tunnel-Maximum-Sessions

The maximum number of sessions allowed per tunnel group (untagged attribute only). This attribute has the same meaning as attribute 26.6527.48 Alc-Tunnel-Max-Sessions:0. No sessions are setup above the limits. Preconfigured values (configure router/service vprn service-id l2tp session-limit) are used when attribute is omitted.

26.4874.64

ERX-Tunnel-Group

The name of the tunnel group that refers to the CLI-created tunnel-group-name context configure router/service vprn service-id l2tp group tunnel-group-name. Any other RADIUS returned L2TP parameter is ignored and other required info to setup the tunnel should come from the CLI-created context. Strings above the limits are treated as a setup failure.

26.6527.46

Alc-Tunnel-Group

The tunnel-group-name that refers to the CLI-created tunnel-group-name context configure router/service vprn service-id l2tp group tunnel-group-name. Any other RADIUS returned L2TP parameter is ignored and other required info to setup the tunnel should come from the CLI-created context. Strings above the limits are treated as a setup failure.

26.6527.47

Alc-Tunnel-Algorithm

Describes how new sessions are assigned (weighted-access, weighted-random or existing-first) to one of the set of suitable tunnels that are available or could be made available. A preconfigured algorithm (configure router/service vprn service-id l2tp session-assign-method) is used when this attribute is omitted.

Attribute value existing-first specifies that the first suitable tunnel is used or set up for the first session and re-used for all subsequent sessions.

The weighted-access attribute value (session-assign-method weighted) specifies that the sessions are equally distributed over the available tunnels; new tunnels are set up until the maximum number is reached; the distribution aims at an equal ratio of the actual number of sessions to the maximum number of sessions. When there are multiple tunnels with an equal number of sessions (equal weight), LAC selects the first tunnel from the candidate list.

The weighted-random attribute value enhances the weighted-access algorithm such that when there are multiple tunnels with an equal number of sessions (equal weight), LAC randomly selects a tunnel.

The maximum number of sessions per tunnel is retrieved using attribute 26.6527.48 Alc-Tunnel-Max-Sessions or set to a preconfigured value if Alc-Tunnel-Max-Sessions is omitted. Values outside the limits are treated as a setup failure.

26.6527.48

Alc-Tunnel-Max-Sessions

The maximum number of sessions allowed per tunnel (if tag is 1 to 31) or per tunnel group (if tag is 0).This attribute has the same meaning as attribute 26.2352.21 Tunnel-Max-sessions and 26.4874.33 ERX-Tunnel-Maximum-Sessions with the only difference that these latter attributes refers to the tunnel group only (untagged attributed). No sessions are setup above the Limits. Preconfigured values (configure router/service vprn service-id l2tp session-limit) are used when attribute is omitted.

26.6527.49

Alc-Tunnel-Idle-Timeout

The period in seconds that an established tunnel with no active sessions (Established-Idle) persists before being disconnected. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp idle-timeout). The tunnel is not disconnected (infinite) without local configured idle-timeout or if the attribute has value -1 (16777215). Values above the Limits are treated as setup failures.

26.6527.50

Alc-Tunnel-Hello-Interval

The time interval in seconds between two consecutive tunnel Hello messages. A value of 0 or -1 (16777215) specifies that the keepalive function is disabled (infinite). The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp hello-interval). Values outside the limits are treated as a setup failure.

26.6527.51

Alc-Tunnel-Destruct-Timeout

The time in seconds that operational data of a disconnected tunnel persists on the node before being removed. Availability of the data after tunnel disconnection allows better troubleshooting. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp destruct-timeout). Values outside the limits are treated as a setup failure.

26.6527.52

Alc-Tunnel-Max-Retries-Estab

The number of retries allowed for established tunnels before their control connection goes down. An exponential back-off mechanism is used for the retransmission interval: the first retransmission occurs after 1 second, the next after 2 seconds, then 4 seconds up to a maximum interval of 8 seconds (1,2,4,8,8,8,8). The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp max-retries-estab). Values outside the limits are treated as a setup failure.

26.6527.53

Alc-Tunnel-Max-Retries-Not-Estab

The number of retries allowed for unestablished tunnels before their control connection goes down. An exponential back-off mechanism is used for the retransmission interval: the first retransmission occurs after 1 second, the next after 2 seconds, then 4 seconds up to a maximum interval of 8 seconds (1,2,4,8,8,8,8). The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp max-retries-not-estab). Values outside the limits are treated as a setup failure.

26.6527.54

Alc-Tunnel-AVP-Hiding

Indicates if data is hidden in the Attribute Value field of an L2TP AVP. The H bit in the header of each L2TP AVP provides a mechanism to indicate to the receiving peer whether the contents of the AVP are hidden or present in cleartext. This feature can be used to hide sensitive control message data such as user passwords or user IDs. All L2TP AVPs are passed in cleartext if the attribute is omitted and corresponds with the nothing value. The sensitive-only value specifies that the H bit is only set for AVPs containing sensitive information. The all value specifies that the H bit is set for all AVPs where it is allowed. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when the attribute is omitted configure router/service vprn service-id l2tp avp-hiding. AVP hiding uses the shared LAC-LNS secret defined in attribute [69] Tunnel-Password or in configuration. If no password is specified, the tunnel setup fails for sensitive-only and all values. Values outside the Limits are treated as a setup failure.

26.6527.97

Alc-Tunnel-Challenge

Indicates whether the tunnel authentication (challenge-response) is to be used. L2TP tunnel-authentication is based on RFC 1994 CHAP authentication and requires the shared-secret defined in attribute [69] Tunnel-Password. The value with tag 0 is used as default for the tunnels where the value is not specified. When the attribute is omitted and no [69] Tunnel-Password attribute is specified, a preconfigured value is used (configure router/service vprn service-id l2tp challenge). When the attribute is omitted and a [69] Tunnel-Password attribute is specified, then the always value is used. When the attribute has the always value, no [69] Tunnel-Password attribute is specified and no preconfigured value exists for the password, then the tunnel setup fails. Values outside the limits are treated as a setup failure.

26.6527.100

Alc-Serv-Id

The service ID on the LNS node where the PPP sessions are established (configure service ies/vprn service-id subscriber-interface ip-int-name group-interface ip-int-name). Preconfigured values are used if attribute is omitted (configure subscriber-mgmt local-user-db local-user-db-name ppp host host-name interface ip-int-name service-id service-id or configure router/service vprn service-id l2tp group ppp default-group-interface ip-int-name service-id service-id). Values above the limits or unreferenced are treated as a setup failure.

26.6527.101

Alc-Interface

Refers to the group interface ip-int-name on LNS node only where the PPP sessions are established (configure service ies/vprn service-id subscriber-interface ip-int-name group-interface ip-int-name lns). Preconfigured values are used if the attribute is omitted (configure subscriber-mgmt local-user-db local-user-db-name ppp host host-name interface ip-int-name service-id service-id or configure router/service vprn service-id l2tp group ppp default-group-interface ip-int-name service-id service-id). Alc-interface names longer than the maximum allowed value are treated as session setup failures.

26.6527.104

Alc-Tunnel-Serv-Id

The service ID from which the tunnel should be established, enables the tunnel origin to be in a VPRN (VRF). The default value equals Base. Values above the limits or unreferenced are treated as a setup failure.

26.6527.120

Alc-Tunnel-Rx-Window-Size

The initial receive window size being offered to the remote peer. This attribute is copied in the AVP 10 L2TP Receive Window Size. The remote peer may send the specified number of control messages before it must wait for an acknowledgment. The value with tag 0 is used as default for the tunnels where the value is not specified. A preconfigured value is used when the attribute is omitted (configure router/service vprn service-id l2tp receive-window-size). Values outside the allowed limits are treated as a setup failure.

26.6527.144

Alc-Tunnel-Acct-Policy

Refers to a preconfigured L2TP tunnel accounting policy name (configure aaa l2tp-accounting-policy policy-name). L2TP tunnel accounting (RFC 2867) can collect usage data based either on L2TP tunnel and L2TP sessions and send these accounting data to a RADIUS server. Different RADIUS attributes such as [66] Tunnel-Client-Endpoint, [67] Tunnel-Server-Endpoint, [68] Acct-Tunnel-Connection, [82] Tunnel-Assignment-ID can be used to identify the tunnel or session. The value with tag 0 is used as default for the tunnels where the value is not specified. Preconfigured values are used when the attribute is omitted (configure router/service vprn service-id l2tp radius-accounting-policy). Unreferenced policy names or policy names longer than the allowed maximum are treated as host setup failures.

26.6527.204

Alc-Tunnel-DF-bit

This attribute is used on an L2TP LAC only. By default, a LAC does not allow L2TP packet fragmentation by sending L2TP toward the LNS with the Do not Fragment (DF) bit set to 1. This DF bit can be set to 0 to allow downstream routers to fragment the L2TP packets. The LAC itself does not fragment L2TP packets. Packets sent with MTU bigger than the allowed size on the LAC egress port are dropped. This attribute is silently ignored if RADIUS returns an Alc-Tunnel-Group attribute. In that case, the tunnel level, group level, or as last resort, the root level configuration is used instead.

26.6527.214

Alc-Tunnel-Recovery-Method

Sets the L2TP LAC failover recovery method to be used for this tunnel: MCS or recovery tunnel (RFC 4951). Preconfigured values are used when the attribute is omitted (configure router/service vprn service-id l2tp failover recovery-method).

When the tunnel recovery method is set to recovery-tunnel but LNS does not support this capability, then the system automatically falls back to mcs.

Values outside the limits are treated as a setup failure.

26.6527.215

Alc-Tunnel-Recovery-Time

Only applicable when the L2TP LAC failover recovery-method is set to recovery-tunnel. Sets the L2TP LAC failover recovery-time to be negotiated with LNS using L2TP failover extensions (RFC 4951). It indicates to the LNS how long it needs to extend its protocol retry timeout before declaring the control channel down. Preconfigured values are used when attribute is omitted (configure router/service vprn service-id l2tp failover recovery-time).

Values outside the limits are treated as a setup failure.

241.26.6527.25

Alc-Steering-Profile

The steering profile that should be applied to perform traffic steering on L2TP LAC. The steering profile is configured in the following CLI context: configure subscriber-mgmt steering-profile name. An L2TP LAC session is successfully set up when a non-existent steering profile name is referenced in an Access-Accept. A CoA containing a non-existent steering profile is rejected. In both cases, the non-existent steering profile is stored in the L2TP LAC session information and becomes active when the profile is configured at a later stage.

To deactivate traffic steering on L2TP LAC, the [26.6527.238] Alc-Remove-Override attribute must be used.

241.26.6527.88

Alc-Serv-Name

The service name on the LNS node where the PPP sessions are established (configure service ies | vprn service-id name service-name subscriber-interface ip-int-name group-interface ip-int-name).

Preconfigured values are used if the attribute is omitted (configure subscriber-mgmt local-user-db local-user-db-name ppp host host-name interface ip-int-name service-id service-id or configure router | service vprn service-id l2tp group ppp default-group-interface ip-int-name service-name service-name). Values that exceed the limits or are unreferenced are treated as a setup failure.

241.26.6527.91

Alc-Tunnel-Serv-Name

The service name from which the tunnel should be established, enables the tunnel origin to be in a VPRN (VRF). The default value equals Base. Values that exceed the limits or are unreferenced are treated as a setup failure.
