Syntax:
[no] preempt-mode
Disables or re-enables preempt mode. In the default mode, a backup router coming up with a higher priority than
another backup that is currently operating as master will take over the master function.
Using the
no
form of the command disables this operation, thus preventing the higher-priority backup from taking
over the master operation from a lower-priority backup.
This command does not prevent an owner router from resuming the master function after recovering from being
unavailable.
Default: Enabled

Default: Disabled

Configuring track interface
Syntax
[no] track interface [port-list|trunk-list]
Allows you to specify a port or port list, or trunk or trunk list, that will be tracked by this virtual router. If the port or
trunk is down, the virtual router switches to the router specified by the priority value. The command is executed in
VRID instance context.
Example:
switch(config)# vlan 25
switch(vlan-25)# vrid 1
switch(vlan-25-vrid-1)# track interface 10-12, Trk1
Configuring track VLAN
NOTE:
The VR's operating VLAN cannot be configured as a tracking VLAN for that VR.
