Quidway S6500 Series Ethernet Switches Chapter 4 Integrated IS-IS Configuration Commands
Huawei Technologies Proprietary
4-23
Description
Using isis timer csnp command, you can configure the interval of sending CSNP
packets on the broadcast network. Using undo isis timer csnp command, you can
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 1.
[Quidway] interface Vlan-interface 1
[Quidway-Vlan-interface1] isis timer csnp 15 level-2
4.1.26 isis timer hello
Syntax
isis timer hello seconds [ level-1 | level-2 ]
undo isis timer hello [ level-1 | level-2 ]
View

Parameter
seconds: Specify the Hello interval, ranging from 3 to 255 and measured in seconds.
The default value is 10 seconds.
level-1: Specify the Level-1 Hello interval.
level-2: Specify the Level-2 Hello interval.
If the level is not specified, it defaults to setting the Hello interval at Level-1-2, that is,
both Level-1 and Level-2 take effect.
Description
Using isis timer hello command, you can configure the interval of sending hello packet
of corresponding level. Using undo isis timer hello command, you can restore the
default value, that is, 10 seconds.
On a broadcast link, level-1 and level-2 hello packets will be sent respectively and their
intervals should also be set respectively. Such settings are unnecessary on
point-to-point links. The shorter the sending interval is, the more system resources are
occupied to send hello packets. Therefore, the interval should be set according to
actual conditions.
