Activating And Shutting Down A Track - HP 7102dl - ProCurve Secure Router Configuration Manual

Network Monitoring
Configuring Network Monitoring
9-30
To enable the track to log changes, from the network monitor track configu-
ration mode context, enter:
Syntax: log-changes
The log-changes command is like the show events command: it displays in
the running-config file, and (as long as you save this configuration to the
startup-config file) it persists when the ProCurve Secure Router is rebooted.
After you enter this command, the ProCurve Secure Router takes these actions
when the track's state changes:
displays a log to the terminal
saves the log to the event history
if you have enabled log forwarding, forwards the log to a syslog server
To enable logging forwarding, enter these commands from the global config-
uration mode context:
Syntax: logging forwarding on
Syntax: logging forwarding receiver-ip <A.B.C.D>
Track logs have a priority of notice (level 3), so make sure that the priority for
logged events and forwarded logs is set at this level or above.
Syntax: logging forwarding priority-level notice

nal, Trusted Network for more information.

Activating and Shutting Down a Track

Unlike a probe, a track is active by default, which means that:
the track's state depends on the status of its probe or probes
the track logs state changes to the terminal and saves those logs to the
event history (if configured to do so)
the track removes faulty routes and reinstates repaired routes (if config-
ured to do so)
You can shut down the track, which, also unlike the probe, forces it into a
permanent Fail state. Be careful: if the track is monitoring a route, it will then
remove that route. If you want the track to stop monitoring the network, but
remain in a Pass state, shut down its probes instead.
