Using Link-Groups

You can restrict active probes to specified links by associating probes with a link-group.

This allows you to probe your remote site at one rate over a private link and a different rate over other links that traverse the Internet, for example.

Use the link-group command to define a link-group. Use the use link-group command to associate a link-group with an active measurement group. Use the active-measurement use-link-group command to associate a link-group with probes that are not defined within an active measurement group.

Misconfigurations, such as incorrectly spelled or undefined link-groups, will be ignored as much as possible by the active-measurement process, and valid probes will be sent even though errors exist in the link-group configurations. However, such inaccuracies will be logged and displayed in the show statistics am-scheduler command output and you can determine where probes are and are not being sent by reading the show active-measurement command output.
