Chapter 9 Configuring Port Tracking

Configuring Port Tracking

Configuring Port Tracking

Port tracking has the following features:

•The application brings the linked port down when the tracked port goes down. When the tracked port recovers from the failure and comes back up again, the tracked port is also brought up automatically (unless otherwise configured).

•You can forcefully continue to keep the linked port down, even though the tracked port comes back up. In this case, you must explicitly bring the port up when required.

Enabling Port Tracking

The port tracking feature is disabled by default in all switches in the Cisco 9000 Family. When you enable this feature, port tracking is globally enabled for the entire switch.

To configure port tracking, enable the port tracking feature and configure the linked port(s) for the tracked port.

Detailed Steps

To enable port tracking, follow these steps:

	Command	Purpose
Step 1
	switch# config t	Enters configuration mode.
Step 2
	switch(config)# feature port-track	Enables port tracking.
	switch(config)# no feature	Removes the currently applied port tracking configuration
	port-track	and disables port tracking.

Information About Configuring Linked Ports

You can link ports using one of two methods:

•Operationally binding the linked port(s) to the tracked port (default).

•Continuing to keep the linked port down forcefully—even if the tracked port has recovered from the link failure.
