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
• You can forcefully continue to keep the linked port down, even though the tracked port comes back up.

Enabling Port Tracking

The port tracking feature is disabled by default in all switches in the Cisco MDS 9000 Series Multilayer
Switches. 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.
To enable port tracking, perform these steps:
Step 1
switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# feature port-track
Enables port tracking.
switch(config)# no feature port-track
(Optional) Removes the currently applied port tracking configuration 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

Binding a Tracked Port Operationally

When you configure the first tracked port, operational binding is automatically in effect. When you use this
method, you have the option to monitor multiple ports or monitor ports in one VSAN.
To operationally bind a tracked port, perform these steps:
