Caveats

PPRC Not Supported with FCIP Write Acceleration

IBM Peer to Peer Remote Copy (PPRC) is not supported with FCIP Write Acceleration.

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.
