Track Interface - HP 7500 Series High Availability Command Reference

When you configure 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.
Associating a track entry with the echo-mode BFD session detects a directly connected link. Before that,
configure the source IP address of BFD echo packets.
Examples
# Create track entry 1, which uses BFD to monitor the link between local IP address 1.1.1.2 and remote IP
address 1.1.1.1 by sending BFD echo packets.
<Sysname> system-view
[Sysname] track 1 bfd echo interface vlan-interface 2 remote ip 1.1.1.1 local ip 1.1.1.2

Parameters
track-entry-number: Track entry ID, which ranges from 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 specified, 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 has changed to Negative. The negative-time argument represents the
delay time, in the range of 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 has changed to Positive. The positive-time argument represents the delay time,
in the range of 1 to 300, in seconds.
