Connectivity to Cisco Fabrics

Workaround for QLogic-based devices

If there are QLogic-based devices behind a switch in AG mode, you must use the Cisco provided

procedures to connect to a Fabric OS switch in AG mode to a Cisco fabric. Cisco software maintains

a list of QLogic-based HBAs. Each HBA is identified by its company ID (also know as Organizational

Unit Identifier, or OUI) used in the PWWN during a fabric log in. You can modify the Cisco Company

ID entries using the CLI.

NOTE

You must set the fcinterop FC ID allocation scheme to auto and use the company ID list and

persistent FC ID configuration to manipulate the FC ID device allocation.

Table 7 shows the Cisco Company ID list, which shows the OUI ID as the three middle bytes of the

World Wide Name (WWN). This OUI ID format is used for initiator devices.

For detailed documentation on the FCID allocation for HBAs, go to:

Editing Company ID List if no FC target devices on switch

You can connect a Cisco MDS switch to a switch in AG mode if there are no FC target devices, such

as storage arrays on the Cisco switch. You can do this by editing the Company ID List or by placing

the Cisco switch FCID allocation mode into FLAT mode.

1. Connect to the switch and log in as admin on the Cisco MDS switch.

2. From the Company ID List, delete the OUI IDs of all the HBAs that are connected through the

switch in AG mode.

3. Delete the OUI IDs if and only if they are in the Company ID List.

4. Enter the following commands to determine the OUIs in the Company ID List:

switch#_show fcid-allocation area
