snmp-agent trap enable feature-name isis
Function
The snmp-agent trap enable feature-name isis command enables the trap function for the IS-IS module.
The undo snmp-agent trap enable feature-name isis command disables the trap function for the IS-IS module.
By default, the isisattempttoexceedmaxsequence alarm function is enabled, while other IS-IS alarm functions are disabled.

Parameters
| Parameter | Description | Value |
|---|---|---|
| trap-name | Specifies the trap name. | - |
| isisadjacencychange | Enables the trap function for neighbor changes. | - |
| isisareamismatch | Enables the trap function when the area address of the received Level-1 Hello packet does not match the local area address. | - |
| isisattempttoexceedmaxsequence | Enables the trap function when the LSP sequence number reaches the maximum value. | - |
| isisauthenticationfailure | Enables the trap function when the authentication password in the received LSP is not the same as the local authentication password. | - |
| isisauthenticationtypefailure | Enables the trap function when the authentication type in the received LSP is not the same as the local authentication type. | - |
| isiscorruptedlspdetected | Enables the trap function when the LSP checksum authentication fails. | - |
| isisdatabaseoverload | Enables the trap function when the LSDB overload status changes. | - |
| isisidlenmismatch | Enables the trap function when the system ID length in the received LSP is not the same as the local system ID length. | - |
| isislsptoolargetopropagate | Enables the trap function when the PDU length exceeds the interface MTU. | - |
| isismanualaddressdrops | Enables the trap function when the number of Level-2 area addresses exceeds the maximum value and some Level-2 area addresses may be lost after IS-IS leaks Level-1 area addresses to the Level-2 area. | - |
| isismaxareaaddressesmismatch | Enables the trap function when the maximum area address in the received LSP does not match the local one. | - |
| isisoriglspbuffsizemismatch | Enables the trap function when the buffer size in the received LSP does not match the local one. | - |
| isisownlsppurge | Enables the trap function when an IS detects that its LSPs are purged on the network. | - |
| isisprotocolssupportedmismatch | Enables the trap function when the protocol type in the received LSP does not match the local protocol type. | - |
| isisrejectedadjacency | Enables the trap function when the neighbor relationship cannot be established after IS-IS receives the Hello packet. | - |
| isissequencenumberskip | Enables the trap function when the local router receives the LSP sent by itself with the sequence number greater than that of the LSP in the local LSDB. | - |
| isisversionskew | Enables the trap function when the version in the Hello packet is incorrect. | - |
Usage Guidelines
To enable the trap function for one or more specific events of the IS-IS module, specify trap-name.
You can run the display snmp-agent trap feature-name isis all command to view all the trap messages of the IS-IS module.
If the IS-IS trap function is enabled before a version upgrade, you need to run the snmp-agent trap enable feature-name isis command to re-enable the trap function after the version upgrade. Otherwise, the previous configuration is lost.
