ipv4: IPv4 protocol status of the interface to be monitored. 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. You can use the display ip interface brief command to display the
IPv4 protocol status of an interface.
delay: Specifies that the track module notifies the application modules of the track entry status change
after a specified 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. negative-time represents the delay time, ranging
from 1 to 300, in 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. positive-time represents the delay time, ranging from 1 to
300, in seconds.
Description
Use the track interface protocol command to create a track entry to be associated with the protocol status
of a specified interface, and specify the delay time for the track module to notify the application modules
when the status of the track entry changes.
Use the undo track command to remove the created track entry.
By default, no track entry to be associated with the protocol status of a specified interface is created.
• After a track entry is created, you cannot modify the content associated with the track entry. You
need to remove the track entry, and then reconfigure it.
• After a track entry is created, you can use the track interface protocol delay command to modify the
delay time for the track module to notify the application modules of the track entry status change.
Related commands: display track.
