Tracking the Interface Priority

Interface state tracking changes the priority of the virtual router based on the state of another interface
in the switch. When the tracked interface is down, the priority reverts to the priority value for the virtual
router (see the
interface is up, the priority of the virtual router is restored to the interface state tracking value. You can
track the state of either a specified VSAN interface or the management interface (mgmt 0). The interface
state tracking feature is disabled by default.
For interface state tracking to function, you must enable preemption on the interface. See the
Note
"Configuring or Enabling Priority Preemption" section on page
To track the interface priority for a virtual router using IPv4, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface vsan 10
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 interface
mgmt 0 priority 2
switch(config-if-vrrp)# no track
To track the interface priority for a virtual router using IPv6, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# interface vsan 12
switch(config-if)#
Step 3
switch(config-if)# vrrp ipv6 200
switch(config-if-vrrp-ipv6)#
Step 4
switch(config-if-vrrp-ipv6)# preempt

Purpose
Assigns the simple text authentication option and
specifies the password for this option.
Assigns the 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.
