Enabling The Trap Function Of Vrrp - H3C S9500 Series Operation Manual

Operation Manual – VRRP
H3C S9500 Series Routing Switches
Configure the
authentication mode and
authentication key when
the VRRP groups send
and receive VRRP
packets
Configure the time interval
for the Master in the
VRRP group to send
VRRP advertisement
Disable TTL check on
VRRP packets
Note:
You may configure different authentication modes and authentication keys for the
VRRP groups on an interface. However, the members of the same VRRP 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.

1.2.7 Enabling the Trap Function of VRRP

After the trap function is enabled for a VRRP module, the VRRP module will generate
traps with severity level errors to report its key events. The generated traps will be sent
to the information center of the device, where you can configure whether to output the
trap information and the output destination. For information center configurations, refer
to Information Center Configuration in the System Volume.
