Configuring a Persistent FCID in an IVR Configuration with Brocade Switches
The following information is relevant if you have a fabric that consists of Cisco MDS 9000 switches and
Brocade switches, and the Cisco MDS switches are running either NX-OS Release 4.x or Release 5.x
and Brocade is running FOS higher than 6.x. In an IVR configuration, when IVR NAT is enabled on a
Cisco MDS 9000 switch, the device in the native VSAN should be configured with a persistent FCID.
Assuming the FCID is 0xAABBCC, AA should be configured with the virtual IVR domain ID of the
VSAN that contains the ISLs and BB should be configured in the following range:
• 1 through 64 if the Brocade switch is operating in native interop mode.
• 1 through 30 if the Brocade switch is operating in McData Fabric mode or McData Open Fabric
Mode.
This configuration ensures that the devices connected to the Cisco MDS 9000 switch can be seen in the
name server database on the Brocade switch.
