Parameter
seconds: Specifies the CSNP packet interval on the broadcast network, ranging from 1
to 65535 and measured in seconds. By default, the value is 10 seconds.
level-1: Specifies the Level-1 CSNP packet interval.
level-2: Specifies the Level-2 CSNP packet interval.
If neither Level-1 nor Level-2 is specified, it defaults to set Level-1-2 Hello message
interval, that is, both Level-1 and Level-2 take effect.
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 Level-2 CSNP packet to be transmitted every 15 seconds on the interface
Serial1/0/0.
[3Com ] interface serial1/0/0
[3Com -Serial1/0/0] isis timer csnp 15 level-2
