packet priority during
transmission.
By default, the DCSP value for
VRRP packets is 48.
Enabling SNMP notifications for VRRP
Perform this task to enable VRRP to report important events through notifications to the SNMP module.
The SNMP module determines how to output the notifications according to the configured output rules.
For more information about notifications, see Network Management and Monitoring Configuration
Guide.
To enable SNMP notifications for VRRP:
