Associating Track With Interface Management - HP A5830 series Configuration Manual

If the BFD detects that the link fails, it informs the track entry of the link failure. The track module
•
then sets the track entry to the Negative state.
If the BFD detects that the link is normal, the track module sets the track entry to the Positive state.
•
For more information about BFD, see the chapter "BFD configuration."
Configuration prerequisites
Before you associate track with BFD, configure the source address of the BFD echo packets.
Configuration procedure
To associate track with BFD:
To do...
• Enter system view
• Create a track entry, associate
it with the BFD session, and
specify the delay time for the
track module to notify the
associated application module
when the track entry status
changes
When associating track with BFD, do not configure the virtual IP address of a VRRP group as the local or
remote address of a BFD session.

Associating track with interface management

The interface management module monitors the physical status or network-layer protocol status of the
interface. The interface management module functions as follows when it is associated with a track
entry:
When the physical or network-layer protocol status of the interface changes to up, the interface
•
management module informs the track module of the change and the track module sets the track
entry to Positive.
When the physical or network-layer protocol status of the interface changes to down, the interface
•
management module informs the track module of the change and the track module sets the track
entry to Negative.
To associate track with interface management:
To do...
• Enter system view
• Create a track entry, associate
it with the interface
management module to
monitor the physical status of
an interface, and specify the
delay time for the track
module to notify the
associated application module
when the track entry status
changes
Use the command...
system-view
track track-entry-number bfd echo interface
interface-type interface-number remote ip
remote-ip local ip local-ip [ delay {
negative negative-time | positive positive-
time } * ]
Use the command...
system-view
track track-entry-number interface
interface-type interface-number [ delay {
negative negative-time | positive positive-
time } * ]
