Usage guidelines
When you create a track entry that is associated with the link state of a specific interface, the state of
the track entry is Positive if the link state of the interface is up. The state of the track entry is Negative
if the link state of the interface is down. To display the link state of an interface, use the
display ip
interface brief
command.
After you create a track entry, you can only use the
track interface delay
command to modify its
notification delay settings. To modify other settings, you must delete the entry and create a new one.
Examples
# Create track entry 1, and associate it with the link state of VLAN-interface 10.
