Configuring The Port-Monitor Portguard Action For Congestion Isolation - Cisco MDS 9000 Series Configuration Manual

Removing an Interface
Step 1
Enter configuration mode:
switch# configure terminal
Step 2 Clear the slow-drain devices that were manually added to be detected as slow devices or excluded from being detected
as slow devices:
switch(config)# no congestion-isolation {include | exclude} pwwn pwwn vsan vsan-id
Step 3
Disable Congestion Isolation:
switch(config)# no feature congestion-isolation
Removing an Interface
Port monitor detects slow devices when a given threshold is reached and triggers the congestion isolation
feature in the switch to move traffic to that slow device into the slow Virtual Link (VL2). The switch does
not automatically remove any devices from congestion isolation. This must be done manually once the problem
with the slow device is identified and resolved.
To manually remove an interface from being detected as slow, perform these steps:
Remove an interface from being detected as slow by the port monitor:
switch#: congestion-isolation remove interface slot/port
