Description
Use the isis timer csnp command to configure the interval of sending CSNP
packets on the broadcast network.
Use the undo isis timer csnp command to restore the default value, that is, 10
seconds.
Only DIS can periodically send CSNP packets, therefore, this command is valid only
for the router that is selected as the DIS. Furthermore, DIS is divided into level-1
and level-2, and their intervals of sending CSNP packets must be set respectively.
Example
# Set the CSNP packet of Level-2 to be transmitted every 15 seconds on the
interface Vlan-interface 10.
[SW8800] interface Vlan-interface 10
