Inter-fabric broadcast frames

The FC router can receive and forward broadcast frames between edge fabrics and between the

backbone fabric and edge fabrics. Many target devices and HBAs cannot handle broadcast frames.

In this case, you can set up broadcast zones to control which devices receive broadcast frames.

(Refer to “Broadcast zones” on page 310 for information about setting up broadcast zones.)

By default, broadcast frames are not forwarded from the FC router to the edge fabrics.

NOTE

Broadcast frame forwarding is not supported in an FCR fabric with a Brocade 8000. By default,

broadcast frame forwarding is disabled on an FC router. If your edge fabric includes a Brocade 8000,

do not enable broadcast frame forwarding on the FC router, because this can degrade FCR

performance when there is excessive broadcast traffic.

Displaying the current broadcast configuration

1. Log in to the FC router as admin.

2. Enter the following command:

fcr:admin> fcrbcastconfig --show

This command displays only the FIDs that have the broadcast frame option enabled. The FIDs

that are not listed have the broadcast frame option disabled.

Enabling broadcast frame forwarding

1. Log in to the FC router as admin.

2. Enter the following command:

fcr:admin> fcrbcastconfig --enable -f fabricID

The fabricID variable is the FID of the edge or backbone fabric on which you want to enable

broadcast frame forwarding. Broadcast frame forwarding is enabled by default.

Disabling broadcast frame forwarding

1. Log in to the FC router as admin.

2. Enter the following command:

fcr:admin> fcrbcastconfig --disable -f fabricID

The fabricID variable is the FID of the edge or backbone fabric on which you want to disable

broadcast frame forwarding.

Resource monitoring

It is possible to exhaust resources, such as proxy PIDs. Whenever a resource is exhausted,

Fabric OS generates an error message. The messages are described in the Fabric OS Message

Reference.
