ISIS/6/IS_RECV_SMALL_RLT_LSP

Message

ISIS/6/IS_RECV_SMALL_RLT_LSP: ISIS receive LSP with small Remaining Lifetime. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], ifIndex=[ifIndex], ifName=[ifName], isisAdjSysID=[hwIsisAdjSysID], isisPduLspId=[isisPduLspId], isisRemainingLifetime=[hwIsisRemainingLifetime])

Description

This object indicates that the Remaining Lifetime of a received LSP is less than 60s.

Parameters

Parameter Name	Parameter Meaning
isisSysInstance	ID of an IS-IS process
isisSysLevelIndex	IS-IS level
isisCircIndex	Index of the interface that received the LSP
isisCircIfIndex	Index of the interface that received the LSP
ifIndex	Interface index
ifName	Name of the interface that received the LSP
hwIsisAdjSysID	System ID of the neighbor that sent the LSP
isisPduLspId	LSP ID
hwIsisRemainingLifetime	Remaining Lifetime of the LSP

Possible Causes

A new LSP generated by another device is received, and the Remaining Lifetime value of the LSP is not 0 and less than 60 seconds.

Procedure

1. Run the display isis lsdb command to check the Holdtime field. This field indicates the value of Remaining Lifetime. Check whether the value is less than 60s.

a. Check whether the Remaining Lifetime of the LSP is less than 60s when the neighbor sent it.

b. Check whether the LSP is an attack packet.

c. Check whether the Remaining Lifetime was changed manually.

If the Remaining Lifetime of the LSP is less than 60s, check whether it was changed manually.
If the Remaining Lifetime was changed manually, no action is required, and go to Step 3.
If the Remaining Lifetime was not changed manually, go to Step 2.
If the Remaining Lifetime of the LSP is not less than 60s, go to Step 2.

2. Collect alarm information and configuration information, and then contact technical support personnel.

3. End.
