Port Tracking Guidelines

Before configuring port tracking, consider the following guidelines:
•
•
•

Port Tracking Features

Port tracking has the following features:
•
•

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.
To enable port tracking, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# port-track enable
switch(config)# no port-track enable

Configuring Linked Ports

You can link ports using one of two methods:
•
•
OL-6973-03, Cisco MDS SAN-OS Release 2.x
Verify that the tracked ports and the linked ports are on the same Cisco MDS switch.
Be aware that the linked port is automatically brought down when the tracked port goes down.
Do not track a linked port back to itself (for example, Port fc1/2 to Port fc2/5 and back to Port fc1/2)
to avoid recursive dependency.
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.
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.
Purpose
