Chapter 33 Configuring Domain Parameters
Verifying fcdomain Information
Purging Persistent FC IDs
To purge persistent FC IDs, perform this task:
Verifying fcdomain Information
Note If the fcdomain feature is disabled, the runtime fabric name in the display is the same as the configured
fabric name.
This example shows how to display information about fcdomain configurations:
switch# show fcdomain vsan 2
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.
switch# show fcdomain domain-list vsan 76
Number of domains: 3
Domain ID WWN
--------- -----------------------
0xc8(200) 20:01:00:05:30:00:47:df [Principal]
0x63(99) 20:01:00:0d:ec:08:60:c1 [Local]
0x61(97) 50:00:53:0f:ff:f0:10:06 [Virtual (IVR)]
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.
Tip 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.
Command Purpose
Step 1
switch# purge fcdomain fcid vsan
vsan-id
Purges all dynamic and unused FC IDs in the specified
VSAN.
switch# purge fcdomain fcid vsan
vsan-id - vsan-id
Purges dynamic and unused FC IDs in the specified VSAN
range.
