About Forceful Shutdown

If a tracked port flaps frequently, then tracking ports using the operational binding feature may cause
frequent topology change. In this case, you may 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
Tip
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.

Forcefully Shutting Down a Tracked Port

To forcefully shut down a tracked port, perform this task:
Command
Step 1
switch# configuration terminal
Step 2
switch(config)# interface fc slot/port
Step 3
switch(config-if)# port-track force-shut
switch(config-if)# no port-track force-shut
Displaying Port Tracking Information
The show commands display the current port tracking settings for the switch.
The following example shows how to display tracked port configuration for a specific interface:
switch# show interface fc2/1
fc2/1 is down (Administratively down)
5 minutes input rate 0 bits/sec, 0 bytes/sec, 0 frames/sec
...
The following example shows how to display tracked port configuration for a SAN port channel:
switch# show interface san-port-channel 1
port-channel 1 is down (No operational members)

Purpose
Enters configuration mode.
Configures the specified interface and enters the
interface configuration mode. You can now
configure tracked ports.
