Verifying The Company Id Configuration; Switch Interoperability - Cisco MDS 9000 Series Configuration Manual

Advanced Features and Concepts

Verifying the Company ID Configuration

You can view the configured company IDs by issuing the show fcid-allocation area command (see
the List of Default and Configured Company IDs, on page
entries are listed next. Entries are listed even if they were part of the default list and you later removed them.

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 issuing the show fcid-allocation
company-id-from-wwn command (see
309). Some WWN formats do not support company IDs. In these cases, you many need to configure
the FC ID persistent entry.

Switch Interoperability

Interoperability enables the products of multiple vendors to interact with each other. Fibre Channel standards
guide vendors towards common external Fibre Channel interfaces.
If all vendors followed the standards in the same manner, then interconnecting different products would
become a trivial exercise. However, not all vendors follow the standards in the same way, thus resulting in
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 more amiable standards-compliant implementation.
