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:
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.
