Setting An Authentication Key; Monitoring Vrrp; Ip-Redundancy Trace - Cabletron Systems SmartSwitch Router User's Reference Manual

Setting an Authentication Key

By default, no authentication of VRRP packets is performed on the SSR. You can specify a
clear-text password to be used to authenticate VRRP exchanges. To enable authentication,
enter the following command in Configure mode:
Set an authentication key for a
virtual router.
where <key> is a clear-text password.
Note:
The SSR does not currently support the IP Authentication Header method of
authentication.

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:
Display a message when any
VRRP event occurs. (Disabled
by default.)
Display a message when a
VRRP router changes from one
state to another; for example
Backup to Master. (Enabled by
default.)
Display a message when a
VRRP packet error is detected.
(Enabled by default.)
Enable all VRRP tracing.
