Description Use track bfd echo to create a track entry, associate it with the BFD session, specify to use echo packets in BFD probes, 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 exists. After a track entry is created, you cannot change its settings except the delay time. To change the delay time for this track entry, use the track bfd echo delay command. To modify other settings of this track entry, first delete the entire track entry, and then create a new track entry. 145

Parameters
track-entry-number
: Specifies a track entry ID, in the range of 1 to 1024.
interface
interface-type interface-number
: Specifies an outgoing interface by its type and number for BFD
echo packets.
remote ip
remote-ip
: Specifies the destination IP address of the BFD echo packets.
local ip
local-ip
: Specifies the source IP address of the BFD echo packets.
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 bfd echo
to create a track entry, associate it with the BFD session, specify to use echo packets
in BFD probes, 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 exists.
After a track entry is created, you cannot change its settings except the delay time. To change the delay
time for this track entry, use the
track bfd echo delay
command. To modify other settings of this track entry,
first delete the entire track entry, and then create a new track entry.
