Creating a Tracking and Failure Detection Process for an Interface
To create a tracking and failure detection process for an interface, use the ft track
interface command in configuration mode. The syntax of this command is:
ft track interface nam
e
For the na
me argument, enter a unique identifier for the tracking process as an
unquoted text string with no spaces and a maximum of 64 alphanumeric
characters.
Note You cannot delete an interface if the ACE is using the interface for tracking. Also,
you cannot configure the FT VLAN for tracking.
For example, enter:
host1/Admin(config)# ft track interface TRACK_VLAN100
To remove the interface-tracking process, enter:
host1/Admin(config)# no ft track interface TRACK_VLAN100
