When configuring collaboration between track and BFD, do not configure the virtual IP address of a VRRP group as the local or remote address of a BFD session. Related commands: display track.

After a track entry is created, you cannot change its settings except the delay time. To change the delay time, use the track interface delay command. To modify other settings of this track entry, first delete the entire track entry, and then create a new track entry. When a track entry to be associated with the physical status of a specific interface is created, the status of the track entry is Positive if the physical status of the interface is up.

Parameters
track-entry-number
: Specifies a track entry ID, in the range of 1 to 1024.
interface-type interface-number
: Specifies an interface by its type and number.
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.
negative-time
represents the delay time in seconds,
in the range of 1 to 300.
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 in seconds, in the
range of 1 to 300.
Description
Use
track interface
to create a track entry, associate it with the physical status of a specific interface, and
specify the delay time for the track module to notify the application modules when the status of the track
entry changes.
Use
undo track
to remove the track entry.
By default, no track entry to be associated with the physical status of a specific interface is created.
After a track entry is created, you cannot change its settings except the delay time. To change the delay
time, use the
track interface delay
command. To modify other settings of this track entry, first delete the
entire track entry, and then create a new track entry.
When a track entry to be associated with the physical status of a specific interface is created, the status
of the track entry is Positive if the physical status of the interface is up. The status of the track entry is
