F3726, F3211, F3174, R5135, R3816-HP Firewalls and UTM Devices Network Management Command Reference-6PW100

422
Parameters
seconds: Specifies on the DIS of a broadcast network the interval in seconds for sending CSNP packets,
ranging from 1 to 600.
level-1: Applies the interval to Level-1.
level-2: Applies the interval to Level-2.
Usage guidelines
This command only applies to the DIS of a broadcast network, which sends CSNP packets periodically
for LSDB synchronization.
If no level is specified, the CSNP interval applies to both Level-1 and Level-2.
Examples
# Configure Level-2 CSNP packets to be sent every 15 seconds over GigabitEthernet 1/1.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/1
[Sysname-GigabitEthernet1/1] isis timer csnp 15 level-2
isis timer hello
NOTE:
This command is not supported in loopback interface view.
Use isis timer hello to specify the interval for sending hello packets.
Use undo isis timer hello to restore the default.
Syntax
isis timer hello seconds [ level-1 | level-2 ]
undo isis timer hello [ seconds ] [ level-1 | level-2 ]
Default
The default hello interval is 10 seconds.

2: System level
Parameters
seconds: Specifies the interval in seconds for sending hello packets, ranging from 3 to 255.
level-1: Specifies the interval for sending Level-1 hello packets.
level-2: Specifies the interval for sending Level-2 hello packets.
Usage guidelines
Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify
an interval for each of the two levels. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello
packets, and you need not specify an interval for each of the two levels.
