Forcefully Shutting Down; Forcefully Shutting Down A Tracked Port - Cisco Nexus 5000 Series Configuration Manual

Configuring Port Tracking

Forcefully Shutting down

If a tracked port flaps frequently, tracking ports using the operational binding feature may cause frequent
topology changes. You might choose to keep the port in the down state until you are able to resolve the reason
for these frequent flaps. Keeping the flapping port in the down state forces the traffic to flow through the
redundant path until the primary tracked port problems are resolved. When the problems are resolved and the
tracked port is back up, you can explicitly enable the interface.
If you configure this feature, the linked port continues to remain in the shutdown state even after the tracked
port comes back up. You must explicitly remove the forced shut state (by administratively bringing up this
interface) of the linked port once the tracked port is up and stable.
