Associating Track With Interface Management - HP MSR Series Configuration Manual

If the BFD detects that the link fails, it informs the Track module of the link failure. The Track module
•
sets the track entry to Negative state.
• If the BFD detects that the link is operating correctly, the Track module sets the track entry to Positive
state.
Before you associate Track with BFD, configure the source IP address of BFD echo packets. For more
information, see "Configuring BFD."
To associate Track with BFD:
Step
1. Enter system view.
2. Create a track entry, and
associate it with a BFD session.

Associating Track with interface management

The interface management module monitors the link status or network-layer protocol status of interfaces.
The associated Track and interface management operate as follows:
When the link or network-layer protocol status of the interface changes to up, the interface
•
management module informs the Track module of the change. The Track module sets the track entry
to Positive state.
• When the link or network-layer protocol status of the interface changes to down, the interface
management module informs the Track module of the change. The Track module sets the track entry
to Negative state.
To associate Track with interface management:
Step
1. Enter system view.
2. Create a track entry, and
associate it with interface
management.

Create a track entry, and associate it
with the interface management module
to monitor the link status of an interface:
track track-entry-number interface
interface-type interface-number [ delay
{ negative negative-time | positive
positive-time } * ]
•
Create a track entry, and associate it
with the interface management module
to monitor the network-layer protocol
status of an interface:
track track-entry-number interface
interface-type interface-number protocol
{ ipv4 | ipv6 } [ delay { negative
negative-time | positive positive-time }
* ]
