To set an authentication option for a virtual router, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface vsan 1
switch(config-if)#
Step 3
switch(config-if)# vrrp 250
switch(config-if-vrrp)#
Step 4
switch(config-if-vrrp)# authentication

switch(config-if-vrrp)# no authentication
Priority Based on Interface State
The tracking feature is disabled by default. When you specify the tracking option, the priority of the
virtual router is changed based on the state of another interface in the switch. When the tracked interface
is down, the priority of the virtual router is changed to a lower priority value. When the tracked interface
is up, the priority of the virtual router is restored to its original value. You can track one of two interfaces
on a switch in the Cisco MDS 9000 Family: a specified VSAN interface or a management interface.
For interface tracking to function, you must enable preemption on the interface. See the
Note
Preemption" section on page
To track the interface priority for a virtual router, follow these steps:
Command

switch(config)# interface vsan 1
switch(config-if)#
Step 3
switch(config-if)# vrrp 250
switch(config-if-vrrp)#
Step 4
switch(config-if-vrrp)# preempt
Step 5
switch(config-if-vrrp)# track

switch(config-if-vrrp)# no track
Displaying VRRP Information
Use the show vrrp vr command to display configured VRRP information (see Examples
OL-6973-03, Cisco MDS SAN-OS Release 2.x
Purpose
Enters configuration mode.
Configures a VSAN interface (VSAN 1).
Creates a virtual router.
Assigns the simple text authentication option and
specifies the password for this option.
Assigns MD5 authentication option and specifies
the key and the unique SPI value for this option.
The SPI and the valid range is 0x100 to
0xFFFFFFFF.
Assigns the no authentication option, which is the
default.
36-20.
