Chapter 30 Configuring and Managing Zones
Advanced Zone Attributes
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 30-2 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 frames are broadcast to all devices in the loop.
Caution If broadcast zoning is enabled on a switch, you cannot configure the interop mode in that VSAN.
Configuring Broadcast Zoning
To broadcast frames in the basic zoning mode using Fabric Manager, follow these steps:
Step 1 Expand a VSAN and then select a zone set in the Logical Domains pane.
Step 2 Click the Policies tab in the Information pane.
You see the Zone policy information in the Information pane in Figure 30-40.

Step 3
