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
