Use this command to configure the IS-IS complete sequence number PDU (CSNP) interval for the interface.
| seconds | Specifies the number of seconds between IS-IS sequence number PDUs on the interface. Valid values are 1 - 600. The default value is 10 seconds. |
| level-1 | (Optional) Specifies that the CSNP interval is applied to level 1 for the interface. |
| level-1-2 | (Optional) Specifies that the CSNP interval is applied to both level 1 and level 2 for the interface (Default). |
| level-2 | (Optional) Specifies that the IS-IS CSNP interval is applied to level 2 for the interface. |
If an IS-IS level is not specified, the level type defaults to both level 1 and level 2.
Interface configuration.
Designated Routers (DRs) send out CSNP packets on the interface to maintain database synchronization.
The “no” form of this command resets the CSNP interval to the default value of 10 seconds for the interface.
This example shows how to configure the IS-IS complete sequence number PDU interval to 15 seconds:
System(rw)->configure System(rw-config)->interface vlan 100 System(rw-config-intf-vlan.0.100)->isis csnp-interval 15 System(rw-config-intf-vlan.0.100)->
