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.
The following example displays 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.
