About Broadcast Zoning

Note
Broadcast zoning is not supported on the Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco
Fabric Switch for IBM BladeCenter.
You can configure broadcast frames in the basic zoning mode. By default, broadcast zoning is disabled and
broadcast frames are sent to all Nx ports in the VSAN. When enabled, broadcast frames are only sent to Nx
ports in the same zone, or zones, as the sender. Enable broadcast zoning when a host or storage device uses
this feature.
Table identifies the rules for the delivery of broadcast frames.

Tip If any NL port attached to an FL port shares a broadcast zone with the source of the broadcast frame, then the

Caution If broadcast zoning is enabled on a switch, you cannot configure the interop mode in that VSAN.
