Advanced Fibre Channel Features
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
00:50:8B
00:60:B0
00:A0:B8
00:E0:69
00:30:AE + <------------- User-added entry
00:32:23 +
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
Switch Interoperability
Interoperability enables the products of multiple vendors to interwork with each other. Fibre Channel standards
guide vendors towards common external Fibre Channel interfaces.
Not all vendors follow the standards in the same way, which results in the need for interoperability modes.
This section briefly explains the basic concepts of these modes.
Each vendor has a regular mode and an equivalent interoperability mode, which specifically turns off advanced
or proprietary features and provides the product with a standards-compliant implementation.
Note
For more information on configuring interoperability for Cisco Nexus devices, see the Cisco MDS 9000
Family Switch-to-Switch Interoperability Configuration Guide.
About Interop Mode
The software supports the following four interop modes:
• Mode 1— Standards-based interop mode that requires all other vendors in the fabric to be in interop
• Mode 2—Brocade native mode (Core PID 0).
• Mode 3—Brocade native mode (Core PID 1).
• Mode 4—McData native mode.
For information about configuring interop modes 2, 3, and 4, see the Cisco MDS 9000 Family Switch-to-Switch
Interoperability Configuration Guide, available at the following location:
