1 See CoA and Disconnect Message: additional rules for wholesale/retail subscriber host identification attributes in a retail service for additional rules to target a wholesale/retail subscriber host in a retail service.
2 For a CoA with as key NAS-Port-Id + IP address/prefix, the NAS-Port-Id is used to lookup the service context and the IP address/prefix is used to lookup the subscriber host within the service. If multiple hosts in the resulting service have the same IP address/prefix (such as in a L2-aware NAT scenario), then the first found host is identified. To make the selection of the host deterministic, the MAC address of one of the hosts can be included with the [26.6527.27] Alc-Client-Hardware-Addr to target that single host.
3 Although a single host is identified, the CoA or Disconnect Message applies to all hosts of a dual stack PPPoE session or IPoE session (if enabled).
4 A maximum of 32 hosts can be targeted in a single CoA or Disconnect Message. When more than 32 hosts are identified, the CoA and Disconnect Message is rejected with [101] Error-Cause attribute value 501 (Administratively Prohibited).
5 If multiple hosts share the same IP in the specified service, then the CoA is rejected (NAK).
6 For a CoA with as key User-Name + IP address/prefix, the User-Name is used to lookup the service context and the IP address/prefix is used to lookup the subscriber host within the service. If multiple hosts in the resulting service have the same IP address/prefix (such as in a L2-aware NAT scenario), then the CoA is rejected. To make the selection of the host deterministic, the MAC address of one of the hosts can be included with the [26.6527.27] Alc-Client-Hardware-Addr to target a single host.

Typically, only a single attribute or set of attributes is used to target a host or a number of hosts: ‟NAS-Port-Id + IP” or ‟Acct-Session-Id” or ‟Alc-Subsc-ID-Str”. If both ‟NAS-Port-Id + IP” and ‟Acct-Session-Id” attributes are specified to identify subscriber hosts, only the host identified by ‟NAS-Port-Id + IP” is targeted. If the identified host is not part of the hosts that would be identified by the ‟Acct-Session-Id” attribute, then the CoA is NAK’d with [101] Error-Cause attribute value 503 Session Context Not Found.

Example:

Change of Authorization(43) id 224 len 81 from 192.168.1.1:32772 vrid 1
    SESSION ID [44] 22 24ADFF0000003D5107AB80   # priority 2
    NAS PORT ID [87] 12 lag-1:10.300            # priority 1
    FRAMED IP ADDRESS [8] 4 10.1.2.251         # priority 1
    VSA [26] 15 Alcatel(6527)
      SLA PROF STR [13] 13 sla-profile-1

The CoA targets the host identified with the combination of [87] NAS-Port-Id and [8] Framed-IP-Address (prio 1) only if the host is also identified by [44] Acct-Session-Id (prio 2), else the CoA is NAK’d.

Following attributes are accepted only if the CoA is targeted to a single host as shown in CoA and Disconnect Message: subscriber host identification attributes:

  • [26.6527.14] Alc-Force-Renew

  • [26.6527.15] Alc-Create-Host

  • [26.6527.98] Alc-Force-Nak

  • [26.6527.130] Alc-AA-Transit-IP

CoA and Disconnect Message: additional rules for wholesale/retail subscriber host identification attributes in a retail service details the rules in addition to CoA and Disconnect Message: subscriber host identification attributes for identification attributes in a CoA or Disconnect Message when targeting a wholesale/retail subscriber host in a retail service.

WLAN-GW migrant users identification attributes

CoA and Disconnect Message: WLAN-GW migrant users identification attributes details the attribute that can be used in a CoA and Disconnect Message to target migrant users. A Disconnect Message removes any existing migrant state for the specified UE. A CoA can only be sent for a UE in portal state to trigger the creation of an ESM or DSM user. In contrast to most CoAs this update is not incremental: the CoA must include all required authentication attributes to create the user. The applicability of attributes is the same as for an Access-Accept message in an authentication procedure.

Dynamic data services identification attributes

This section details the attributes that can be used in a CoA and Disconnect Message to identify Dynamic Data Services associated with a dynamic service data trigger. To identify Dynamic Data Services associated with an Enhanced Subscriber Management (ESM) control channel, the CoA and Disconnect Messages must be sent to the control channel. See section "Subscriber host identification attributes" for attributes that can be used as key.

CoA and Disconnect Message: data triggered dynamic services identification attributes lists the attributes that can be used in a CoA and Disconnect Message to identify one or multiple Dynamic Data Services associated with a dynamic service data trigger.

Acct-Session-Id

Accounting session ID of a dynamic services data trigger (can be displayed with "show service dynamic-services data-triggers [sap sap-id]"):

  • Identifies a single dynamic service.

  • Modify and Teardown actions are supported in CoA.

  • Only a single dynamic service is deleted with a Disconnect Message.

Accounting session ID of a dynamic services sap associated with a dynamic services data trigger (can be displayed with "show service dynamic-services saps summary [sap sap-id]"):

  • Identifies a single dynamic service.

  • Modify and Teardown actions are supported in CoA.

  • The identified dynamic service is deleted with a Disconnect Message.

87

NAS-Port-Id

Targets a dynamic services sap-id:

  • Identifies a single dynamic service.

  • Modify and Teardown actions are supported in CoA.

  • The identified dynamic service is deleted with a Disconnect Message.

Note - If the sap-id corresponds with the sap-id of a dynamic services data trigger, then all dynamic data services associated with that data trigger are deleted in case of a Teardown action in CoA or a Disconnect Message.

201

Residual Session Context Removed

Residual Session Context Removed is sent in response to a Disconnect-Request if one or more user sessions are no longer active, but residual session context was found and successfully removed. This value is only sent within a Disconnect-ACK and must not be sent within a CoA-ACK, Disconnect-NAK, or CoA-NAK.

202

Invalid EAP Packet (Ignored)

Invalid EAP Packet (Ignored) is a non-fatal error that must not be sent by implementations of this specification.

401

Unsupported Attribute

Unsupported Attribute is a fatal error sent if a Request contains an attribute (such as a Vendor-Specific or EAP-Message Attribute) that is not supported.

402

Missing Attribute

Missing Attribute is a fatal error sent if critical attributes (such as NAS or session identification attributes) are missing from a Request.

✓

403

NAS Identification Mismatch

NAS Identification Mismatch is a fatal error sent if one or more NAS identification attributes do not match the identity of the NAS receiving the Request.

✓

404

Invalid Request

Invalid Request is a fatal error sent if some other aspect of the Request is invalid, such as if one or more attributes (such as EAP-Message Attributes) are not formatted properly.
