Verifying Congestion Isolation
This example shows how to verify the global list of devices that were detected as slow in a fabric when the
Congestion Isolation feature was enabled. The global list should be the same on all switches in the fabric
where the Congestion Isolation feature is enabled.
switch# show congestion-isolation global-list vsan 4
Global list for vsan 4 PWWN(FCID)

This example shows the list of devices that were detected as slow on remote switches (not locally detected
slow devices):
switch# show congestion-isolation remote-list vsan 4
Remote list for vsan 4
===============================================
10:00:00:00:c9:f9:16:8d(0xbe0000)
This example shows a single device that is marked as slow (feature slow-dev) either via the port monitor or
the congestion isolation include command:
switch# show congestion-isolation include-list vsan 4
Include list for vsan 4
=========================================================

switch# show fcns database vsan 4

This example shows the list of devices that were manually configured using Congestion Isolation exclude list
command on a local switch:
switch# show congestion-isolation exclude-list vsan 4
Exclude list for vsan 4
