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])
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. |
isisAdjSysID |
System ID of the neighbor that sent the LSP. |
isisPduLspId |
LSP ID. |
isisRemainingLifetime |
Remaining Lifetime of the LSP. |
Possible Causes
The local device received an LSP generated by another device, and the LSP was newer than the corresponding LSP stored locally. In addition, the Remaining Lifetime of the LSP was non-zero and less than 60s.
Procedure
- Run thedisplay isis lsdb command to check the Holdtime field. This field indicates the value of Remaining Lifetime. Check whether the value is less than 60s.
- Check whether the Remaining Lifetime of the LSP is less than 60s when the neighbor sent it.
- Check whether the LSP is an attack packet.
- 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.
- Collect the relevant information and contact technical support personnel technical support personnel.
- End.
