Configuration of HSRP
2-4
Table LC-2-4 Set HSRP authorization word
Operation Command
Set HSRP authorization word standby [group-number] authentication [string]
By default, the value of group-number is 0 and the authorization word string is
“quidway”. The length of the authorization word should not exceed 8 characters .
Note:
The same authorization word must be set in the same hot standby group.
2.2.6 Setting HSRP Timer
Routers in the same HSRP hot standby group check each other’s s tate thro ugh hello-
time packets sent among each other: if no hello-packet is received from a router during
a hold-time, this router is then considered as being turned off or some fault has
occurred. By setting HSRP timer hello-time and hold-time are adj usted for sending
hello-packets.
Please use the following commands in the Ethernet interface configurat ion mode.
Table LC-2-5 Set HSRP timer
Operation Command
Set HSRP timer standby [group-number] timers [hello-time] [hold-time]
Both hello-time and hold-time have a value range of 1~255 an d have sec ond as their
unit, their default values are 3 and 10 seconds respectively.
Note:
The same hello-time and hold-time must be set in the same hot standby group and hold-time must be
longer than hold-time.
2.2.7 Monitoring the Specified Interface
The interface monitoring function of HSRP expands backup function sat isfactorily:
backups are available not only for a router when it goes wrong but for an interface of a
router in case it’s not usable. After the interface monitoring function is s et, th e r out er’s
priority will be adjusted dynamically according to the state of the interf ace that is under
monitoring. Once the monitored interface becomes unavailable, the priorit y value of
this router will be reduced, so that another router with a more stable interface state in
the same backup group can become the active one, or preempt to be the active one.
Please use the following commands in the Ethernet interface configurat ion mode.
