Configuration Restrictions And Guidelines; Monitor Link Configuration Task List; Enabling Monitor Link Globally; Creating A Monitor Link Group - HP 5130 EI Series Configuration Manual

A monitor link group works independently of other monitor link groups. When a monitor link group does
not contain any uplink interface or all its uplink interfaces are down, the monitor link group goes down.
It forces all downlink interfaces down at the same time. When any uplink interface comes up, the monitor
link group comes up and brings up all the downlink interfaces.

Configuration restrictions and guidelines

Follow these restrictions and guidelines when you configure Monitor Link:
Do not manually shut down or bring up the downlink interfaces in a monitor link group.
•
To avoid frequent state changes of downlink interfaces in the event that uplink interfaces in the
•
monitor link group flap, you can configure a switchover delay. The switchover delay is the time that
the downlink interfaces wait before they come up following an uplink interface.
