Operation Manual – VRRP
H3C S5500-EI Series Ethernet Switches
Enter system view
Enter the specified
interface view
Configure the
authentication mode and
authentication key when
the standby groups send
and receive VRRP
packets
Configure the time interval
for the Master in the
standby group to send
VRRP advertisement
Disable TTL check on
VRRP packets
Note:
You may configure different authentication modes and authentication keys for the
standby groups on an interface. However, the members of the same standby group
must use the same authentication mode and authentication key.
Factors like excessive traffic or different timer setting on switches can cause the
Backup timer to time-out abnormally and trigger a change of the state. To solve this
problem, you can prolong the time interval to send VRRP packets and configure a
preemption delay.
