ISIS_1.3.6.1.3.37.2.0.14 isisLSPTooLargeToPropagate
Description
ISIS/4/LARGE_LSP:OID [oid] The length of the PDU to be sent is greater than the MTU. (sysInstance=[integer], sysInstanceofLevel=[integer], sysLevel=[integer], sysInstanceofCircIfIndex=[integer], circIndex=[integer], circIfIndex=[integer], lspSizeSupport=[integer], pduLspId=[opaque])
The length of the PDU to be sent is greater than the MTU of the interface.
Parameters
| Name | Meaning |
|---|---|
oid |
Indicates the MIB object ID of the alarm. |
sysInstance |
IS-IS process ID |
sysInstanceofLevel |
IS-IS process ID |
sysLevel |
IS-IS level:
|
sysInstanceofCircIfIndex |
IS-IS process ID |
circIndex |
Interface index |
circIfIndex |
IS-IS interface index |
lspSizeSupport |
Maximum LSP length |
pduLspId |
LSP ID |
Procedure
- Run the display ip interface interface-type interface-number command to view the interface MTU. The Maximum Transmit Unit in the command output shows the MTU value.
- Run the display current-configuration configuration isis command to view the maximum LSP length. lsp-length originate in the command output shows the maximum LSP length. If the command output does not show a setting, the default value is used. The default maximum LSP is 1497 bytes.
- Run the lsp-length originate command in the IS-IS view to change the maximum LSP length to a value smaller than the interface MTU.
- Check whether the alarm is cleared.
If the alarm is cleared, go to Step 6.
If the alarm persists, go to Step 5.
- Collect alarm information and configuration information, and then contact technical support personnel.
- End.
