Cisco MDS 9000 Family Fabric Manager Configuration Guide
OL-6965-03, Cisco MDS SAN-OS Release 2.x
Chapter 15 Zone Configuration
About LUN Zoning
Configuring Zone QoS and Broadcast Attributes
QoS attribute-specific configuration changes take effect when you activate the zone set of the associated
zone.
Note If a member is part of two zones with two different QoS attributes, the higher QoS value is implemented.
This situation does not arise in the VSAN-based QoS as the first matching entry is implemented.
As of Cisco MDS SAN-OS Release 2.0(1b), you can configure broadcast frames in the basic zoning
mode. By default, broadcast zoning is disabled. When enabled, broadcast frames are sent to all Nx Ports.
Broadcast zoning can only be implemented in Cisco MDS 9000 Family switches running Cisco MDS
SAN-OS Release 2.0(1b) or later.
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 implemented in a switch, you cannot configure the interop mode in that VSAN.
To configure the zone QoS or broadcast attributes in Fabric Manager, follow these steps:
Step 1 Choose VSANxxx > <zone set name> from the Fabric Manager Logical Domains menu tree, and click
the Policies tab in the Information pane.
You see the Zone policy information in the Information pane.
Step 2 Check the QoS check box to enable QoS on the default zone.
Step 3 Click QoS Priority and choose low, medium, or high from the pull-down menu.
Step 4 Check the Broadcast check box to enable broadcast frames on the default zone.
Step 5 Click the Apply Changes icon to save these changes or click the Undo Changes icon to discard these
changes.
About LUN Zoning
Logical unit number (LUN) zoning is a feature specific to switches in the Cisco MDS 9000 Family.
Caution LUN zoning can only be implemented in Cisco MDS 9000 Family switches. If LUN zoning is
implemented in a switch, you cannot configure the interop mode in that switch.
Note LUN zoning can be implemented in Cisco MDS 9000 Family switches running Cisco MDS SAN-OS
Release 1.2(x) or earlier.
