Inter-fabric broadcast frames

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
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.

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.
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.
