You can view the configured company IDs by entering the show fcid-allocation area command. Default entries are listed first and the user-added entries are listed next. Entries are listed even if they were part of the default list and you later removed them.
This example shows how to display the list of default and configured company IDs:
switch# show fcid-allocation area
FCID area allocation company id info:
00:50:2E <--------------- Default entry
00:30:AE + <------------- User-added entry
00:E0:8B * <------------- Explicitly deleted entry (from the original default list)
Total company ids: 7
+ - Additional user configured company ids.
* - Explicitly deleted company ids from default list.
You can implicitly derive the default entries shipped with a specific release by combining the list of Company IDs displayed without any identification with the list of deleted entries.
You can also view or obtain the company IDs in a specific WWN by entering the show fcid-allocation company-id-from-wwn command. Some WWN formats do not support company IDs. In these cases, you many need to configure the FC ID persistent entry.
This example shows how to display the company ID for the specified WWN:
switch# show fcid-allocation company-id-from-wwn 20:00:00:05:30:00:21:60
Extracted Company ID: 0x000530
