About Tracking Multiple Ports

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.

About Monitoring Ports in a VSAN

You can optionally configure one VSAN from the set of all operational VSANs on the tracked port with the
linked port by specifying the required VSAN. This level of flexibility provides higher granularity in tracked
ports. In some cases, when a tracked port is a TE port, the set of operational VSANs on the port can change
dynamically without bringing down the operational state of the port. In such cases, the port VSAN of the
linked port can be monitored on the set of operational VSANs on the tracked port.
If you configure this feature, the linked port is up only when the VSAN is up on the tracked port.

Enters configuration mode.
Configures the specified interface and enters the
interface configuration mode. You can now configure
tracked ports.
Tracks the linked port with the specified interface.
When the tracked port goes down, the linked port is
also brought down.
