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 state. When the IPv4 protocol state of an interface is up, the state of the

track object is Positive. When the IPv4 protocol state of an interface is down, the state of the track object

is Negative. To display the IPv4 protocol state of an interface, use the display ip interface brief

command.

ipv6: Monitors the IPv6 protocol state. When the IPv6 protocol state of an interface is up, the state of the

track object is Positive. When the IPv6 protocol state of an interface is down, the state of the track object

is Negative. To display the IPv6 protocol state of an interface, use the display ipv6 interface brief

command.

delay: Specifies the amount of time the Track module waits before notifying the application modules that

the track entry state has changed. If this keyword is not specified, the Track module notifies the

application modules immediately when the track entry state changes.

negative negative-time: Specifies the amount of time the Track module waits before notifying the

application modules that the state of the track entry has changed to Negative. The negative-time

argument represents the delay time in the range of 1 to 300 seconds.

positive positive-time: Specifies the amount of time the Track module waits before notifying the

application modules that the state of the track entry has changed 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 can only use the track interface protocol delay command to modify its

notification delay settings. To modify other settings, you must delete the entry and create a new one.
