Use the
show fcdomain domain-list
command to display the list of domain IDs of all switches belonging to
a specified VSAN. This list provides the WWN of the switches owning each domain ID. The next example
uses the following values:
•
A switch with WWN of 20:01:00:05:30:00:47:df is the principal switch and has domain 200.
•
A switch with WWN of 20:01:00:0d:ec:08:60:c1 is the local switch (the one where you typed the CLI
command to show the domain-list) and has domain 99.
•
The IVR manager obtained virtual domain 97 using 20:01:00:05:30:00:47:df as the WWN for a virtual
switch.

Use the
show fcdomain allowed vsan
command to display the list of allowed domain IDs configured on this
switch..
switch#
show fcdomain allowed vsan 1
Assigned or unallowed domain IDs: 1-96,100,111-239.
[Interoperability Mode 1] allowed domain IDs: 97-127.
[User] configured allowed domain IDs: 50-110.
Ensure that the requested domain ID passes the switch software checks, if interop 1 mode is required in this
switch.
The following example shows how to display all existing, persistent FC IDs for a specified VSAN. You can
also specify the unused option to view only persistent FC IDs that are still not in use.
switch# show fcdomain fcid persistent vsan 1000
The following example shows how to display frame and other fcdomain statistics for a specified VSAN or
SAN port channel:
switch#
show fcdomain statistics vsan 1
VSAN Statistics
Number of Principal Switch Selections: 5
Number of times Local Switch was Principal: 0
Number of 'Build Fabric's: 3
Number of 'Fabric Reconfigurations': 0
The following example shows how to display FC ID allocation statistics including a list of assigned and free
FC IDs:
switch#
show fcdomain address-allocation vsan 1
The following example shows how to display the valid address allocation cache. The cache is used by the
principal switch to reassign the FC IDs for a device (disk or host) that exited and reentered the fabric. In the
cache content, VSAN refers to the VSAN that contains the device, WWN refers to the device that owned the
FC IDs, and mask refers to a single or entire area of FC IDs.
switch#
show fcdomain address-allocation cache
