> # Guidelines and Limitations

> Before configuring port tracking, consider the following guidelines:

> - Verify that the tracked ports and the linked ports are on the same Cisco MDS switch.
> - 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.
> - Be aware that the linked port is automatically brought down when the tracked port goes down. Be aware that the linked port is automatically brought down when the tracked port goes down.
