Monitoring VRRP
The SSR provides two commands for monitoring a VRRP configuration: ip-redundancy
trace
, which displays messages when VRRP events occur, and ip-redundancy show,
which reports statistics about virtual routers.
ip-redundancy trace
The ip-redundancy trace command is used for troubleshooting purposes. This command
causes messages to be displayed when certain VRRP events occur on the SSR. To trace
VRRP events, enter the following commands in Enable mode:
ssr(config)# ip-redundancy set vrrp 1 interface int1 auth-type text auth-key yago
Display a message when any
VRRP event occurs. (Disabled

VRRP router changes from one
state to another; for example
Backup to Master. (Enabled by

enabled
Display a message when a
VRRP packet error is detected.
(Enabled by default.) ip-redundancy trace vrrp packet-errors
