[Tree] (config>system>thresholds kb-memory-use-alarm)

Full Context

configure system thresholds kb-memory-use-alarm

Description

This command configures memory use, in kilobytes, alarm thresholds.

The no form of the command removes the parameters from the configuration.

Parameters

rising-threshold threshold

Specifies a threshold for the sampled statistic. When the current sampled value is greater than or equal to this threshold, and the value at the last sampling interval was less than this threshold, a single threshold crossing event will be generated. A single threshold crossing event will also be generated if the first sample taken is greater than or equal to this threshold and the associated startup-alarm is equal to rising or either.

After a rising threshold crossing event is generated, another such event will not be generated until the sampled value falls below this threshold and reaches less than or equal the falling-threshold value.

The threshold value represents units of kilobytes.

Values

-2147483648 to 2147483647

Default

0

falling-threshold threshold

Specifies a threshold for the sampled statistic. When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single threshold crossing event will be generated. A single threshold crossing event will also be generated if the first sample taken is less than or equal to this threshold and the associated startup-alarm is equal to falling or either.

After a falling threshold crossing event is generated, another such event will not be generated until the sampled value rises above this threshold and reaches greater than or equal the rising-threshold value.

The threshold value represents units of kilobytes.

Values

-2147483648 to 2147483647

Default

0

seconds

Specifies the polling period over which the data is sampled and compared with the rising and falling thresholds.

Values

1 to 2147483647

rmon-event-type

Specifies the type of notification action to be taken when this event occurs.

Values

log — In the case of log, an entry is made in the RMON-MIB log table for each event occurrence. This does not create an SR OS logger entry. The RMON-MIB log table entries can be viewed using the show>system>thresholds CLI command.

trap — An SR OS logger event is generated. The SR OS logger utility then distributes the notification of this event to its configured log destinations which may be CONSOLE, telnet session, memory log, cflash file, syslog, or SNMP trap destinations logs.

both — Both an entry in the RMON-MIB logTable and an SR OS logger event are generated.

none — No action is taken.

Default

both

startup-alarm alarm-type

Specifies the alarm that may be sent when this alarm is first created. If the first sample is greater than or equal to the rising threshold value and startup-alarm is equal to rising or either, then a single rising threshold crossing event is generated. If the first sample is less than or equal to the falling threshold value and startup-alarm is equal to falling or either, a single falling threshold crossing event is generated.

Values

rising, falling, either

Default

either

Full Context

configure system thresholds kb-memory-use-warn

Description

This command configures memory usage, in kilobytes, for warning thresholds

Parameters

rising-threshold threshold

Specifies a threshold for the sampled statistic. When the current sampled value is greater than or equal to this threshold, and the value at the last sampling interval was less than this threshold, a single threshold crossing event will be generated. A single threshold crossing event will also be generated if the first sample taken is greater than or equal to this threshold and the associated startup-alarm is equal to rising or either.

After a rising threshold crossing event is generated, another such event will not be generated until the sampled value falls below this threshold and reaches less than or equal the falling-threshold value.

The threshold value represents units of kilobytes.

Values

-2147483648 to 2147483647

Default

0

falling-threshold threshold

Specifies a threshold for the sampled statistic. When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single threshold crossing event will be generated. A single threshold crossing event will also be generated if the first sample taken is less than or equal to this threshold and the associated startup-alarm is equal to falling or either.

Context

[Tree] (config>service>sdp keep-alive)

Full Context

configure service sdp keep-alive

Description

This command enables the context to configure SDP connectivity monitoring keepalive messages for the SDP ID.

SDP ID keepalive messages use SDP Echo Request and Reply messages to monitor SDP connectivity. The operating state of the SDP is affected by the keepalive state on the SDP ID. SDP Echo Request messages are only sent when the SDP ID is completely configured and administratively up. If the SDP ID is administratively down, keepalives for that SDP ID are disabled. SDP Echo Requests (when sent for keepalive messages) are always sent with the originator-sdp-id. All SDP ID keepalive SDP Echo Replies are sent using generic IP/GRE OAM encapsulation.

When a keepalive response is received that indicates an error condition, the SDP ID will immediately be brought operationally down. Once a response is received that indicates the error has cleared and the hold-down-time interval has expired, the SDP ID will be eligible to be put into the operationally up state. If no other condition prevents the operational change, the SDP ID will enter the operational state.

A set of event counters track the number of keepalive requests sent, the size of the message sent, non-error replies received and error replies received. A keepalive state value is kept indicating the last response event. A keepalive state timestamp value is kept indicating the time of the last event. With each keepalive event change, a log message is generated indicating the event type and the timestamp value.

Keepalive Interpretation and Effect of SDP Echo Reply describes the keepalive interpretation of SDP echo reply response conditions and the effect on the SDP ID operational status.

Full Context

configure service vprn subscriber-interface group-interface srrp keep-alive-interval

configure service ies subscriber-interface group-interface srrp keep-alive-interval

Description

This command defines the interval between SRRP advertisement messages sent when operating in the master state. The interval is also the basis for setting the master-down timer used to determine when the master is no longer sending. The system uses three times the keep-alive interval to set the timer. Every time an SRRP advertisement is seen that is better than the local priority, the timer is reset. If the timer expires, the SRRP instance assumes that a master does not exist and initiates the attempt to become master.

When in backup state, the SRRP instance takes the keep-alive interval of the master as represented in the masters SRRP advertisement message. Once in master state, the SRRP instance uses its own configured keep-alive interval.

The keep-alive-interval may be changed at any time, but will have no effect until the SRRP instance is in the master state.

The no form of this command restores the default interval.

Default

keep-alive-interval 10

Parameters

interval

Specifies the interval, in deciseconds, between SRRP advertisement messages sent when operating in the master state.

configure subscriber-mgmt bgp-peering-policy keepalive

Description

This command configures the BGP keepalive timer. A keepalive message is sent every time this timer expires.

The keepalive value is generally one-third of the hold-time interval. Even though the OS implementation allows the keepalive value and the hold-time interval to be independently set, under the following circumstances, the configured keepalive value is overridden by the hold-time value:

If the specified keepalive value is greater than the configured hold-time, then the specified value is ignored, and the keepalive is set to one third of the current hold-time value.

If the specified hold-time interval is less than the configured keepalive value, then the keepalive value is reset to one third of the specified hold-time interval.

If the hold-time interval is set to zero, then the configured value of the keepalive value is ignored. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

Description

This command configures the BGP keepalive timer. A keepalive message is sent every time this timer expires. The seconds parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

The keepalive value is generally one-third of the hold-time interval. Even though the OS implementation allows the keepalive value and the hold-time interval to be independently set, under the following circumstances, the configured keepalive value is overridden by the hold-time value:

If the specified keepalive value is greater than the configured hold-time, then the specified value is ignored, and the keepalive is set to one third of the current hold-time value.

If the specified hold-time interval is less than the configured hold-time value, then the keepalive value is reset to one third of the specified hold-time interval.

If the hold-time interval is set to zero, then the configured value of the keepalive value is ignored. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

configure router ldp interface-parameters ipv4 keepalive

configure router ldp targeted-session peer-template keepalive

Description

This command configures the time interval (in s), that LDP waits before tearing down the session. The factor parameter derives the keepalive interval.

The config>router>ldp>if-params>ipv6>keepalive and config>router>ldp>targ-session>ipv6>keepalive commands are not supported on the 7450 ESS.

If no LDP messages are exchanged for the configured time interval, the LDP session is torn down. Keepalive timeout is usually three times the keepalive interval. To maintain the session permanently, regardless of the activity, set the value to zero.

When LDP session is being set up, the keepalive timeout is negotiated to the lower of the two peers. Once an operational value is agreed upon, the keepalive factor is used to derive the value of the keepalive interval.

The no form of the command at the interface-parameters and targeted-session levels sets the keepalive timeout and the keepalive factor to the default value.

The no form of this command, at the interface level, sets the keepalive timeout and the keepalive factor to the value defined under the interface-parameters level.

The no form of this command, at the peer level, sets the keepalive timeout and the keepalive factor to the value defined under the targeted-session level.

The session must be flapped for the new settings to operate.

Default

Timeout Factor Defaults lists the default values.

Parameters

timeout

Configures the time interval, in seconds, that LDP waits before tearing down the session.

Values

1 to 65535

factor

Specifies the number of keepalive messages, expressed as a decimal integer, that should be sent on an idle LDP session in the keepalive timeout interval.

configure router bgp group neighbor keepalive

configure router bgp keepalive

Description

This command configures the BGP keepalive timer. A keepalive message is sent every time this timer expires.

The keepalive parameter can be set at three levels: global level (applies to all peers), group level (applies to all peers in peer-group) or neighbor level (only applies to specified peer). The most specific value is used.

The keepalive value is generally one-third of the hold-time interval. Even though the implementation allows the keepalive value and the hold-time interval to be independently set, under the following circumstances, the configured keepalive value is overridden by the hold-time value:

• If the specified keepalive value is greater than the configured hold-time, then the specified value is ignored and the keepalive is set to one third of the current hold-time value.

• If the specified hold-time interval is less than the configured keepalive value, then the keepalive value is reset to one third of the specified hold-time interval.

• If the hold-time interval is set to zero, then the configured value of the keepalive value is ignored. This means that the connection with the peer is up permanently and no keepalive packets are sent to the peer.

The no form of this command used at the global level reverts to the default value.

The no form of this command used at the group level reverts to the value defined at the global level.

The no form of this command used at the neighbor level reverts to the value defined at the group level.

Default

keepalive 30

Parameters

Full Context

configure mcast-management mcast-info-policy bundle keepalive-override

configure mcast-management mcast-info-policy bundle channel keepalive-override

configure mcast-management mcast-info-policy bundle channel source-override keepalive-override

Description

This command configures the keepalive timer override. The PIM (S,G) Keepalive Timer (KAT) is used to maintain the (S,G) state when (S,G) join is not received. Expiry of the KAT causes the (S,G) entry to be removed.

The KAT override configuration is performed with a multicast information policy, which must be applied to the related PIM routing instance. When a KAT override is configured under a channel (a group or a group range), it applies to all (S,G) entries that fall under it, except when the source-override is configured and a KAT override is also configured under the source-override. In this scenario, the specific KAT override must be used for the (S,G) entries that fall under the source-override, while other (S,G) entries under the bundle use the KAT override configured under the channel.

Parameters

keepalive-timer

Specifies the keepalive timer override, in seconds.

Values

10 to 86000

configure system security ssh server-kex-list kex

configure system security ssh client-kex-list kex

Description

This command allows the user to configure phase 1 SSH v2 KEX algorithms for SR OS as an SSH server or an SSH client. By default, the client and server lists are empty. If the user configures this list, SSH uses the hard-coded list with the first-listed algorithm having the highest priority and so on. An empty server or client list is the default list and contains the following algorithms:

diffie-hellman-group16-sha512

diffie-hellman-group14-sha256

diffie-hellman-group14-sha1

diffie-hellman-group14-sha1

diffie-hellman-group1-sha1

The no form of this command removes the specified KEX index. If all KEX indexes are removed, the default list is used again.

Parameters

index

Specifies the index of the algorithm in the list. The lowest index in the list is negotiated first on the SSH negotiation list, while the highest index is at the bottom of the SSH negotiation list.

Values

1 to 255

kex-name

Specifies the KEX algorithm for computing the shared secret key.

Values

diffie-hellman-group16-sha512, diffie-hellman-group14-sha256, diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1
