Parameters
track-entry-number: Specifies the track entry ID in the range of 1 to 1024.
interface-type interface-number: Specifies an interface by its type and number.
ipv4: Monitors the IPv4 protocol status. When the IPv4 protocol status of an interface is up, the status of
the track object is Positive. When the IPv4 protocol status of an interface is down, the status of the track
object is Negative. To display the IPv4 protocol status of an interface, use the display ip interface brief
command.
ipv6: Monitors the IPv6 protocol status. When the IPv6 protocol status of an interface is up, the status of
the track object is Positive. When the IPv6 protocol status of an interface is down, the status of the track
object is Negative. To display the IPv6 protocol status of an interface, use the display ipv6 interface
command.
delay: Specifies that the Track module notifies the application modules of the track entry status change
after a specific delay time. If this keyword is not provided, the Track module notifies the application
modules immediately when the track entry status changes.
negative negative-time: Specifies the delay time for the Track module to notify the application modules
that the status of the track entry changes to Negative. The negative-time argument represents the delay
time in the range of 1 to 300 seconds.
positive positive-time: Specifies the delay time for the Track module to notify the application modules that
the status of the track entry changes to Positive. The positive-time argument represents the delay time in
the range of 1 to 300 seconds.
Usage guidelines
After a track entry is created, you cannot change its settings except the delay time. To change the delay
time, use the track interface protocol delay command. To modify other settings of this track entry, first
delete the entire track entry, and then create a new track entry.
