About Tracking Multiple Ports

You can control the operational state of the linked port based on the operational states of multiple tracked
ports. When more than one tracked port is associated with a linked port, the operational state of the linked
port will be set to down only if all the associated tracked ports are down. Even if one tracked port is up, the
linked port will stay up.
In the following figure, only if both ISLs 2 and 3 fail, will the direct link 1 be brought down. Direct link 1
will not be brought down if either 2 or 3 are still functioning as desired.
