Fabric OS 5.3.0 administrator guide 251
fcrbcastconfig command to set edge fabrics to receive broadcast frames. On switches with an earlier
Fabric OS version than v5.3.0 that do not support broadcast zoning, the fcrbcastconfig command
sets up inter-fabric broadcast frame forwarding on the FC router and prevents inter-fabric forwarding of
broadcast frames to the switches running older versions of firmware.
Between FC routers, the broadcast frame is sent through the FC router protocol frame. The
fcrbcastconfig command allows you to configure VEX/EX_Ports to enable or disable broadcast
capability. The device that originates the broadcast frame must be imported in order to broadcast over FC
routers.
fcrbcastconfig configuration information does not propagate to other FCRs in the backbone fabric. If
you configure one FCR you must configure all the FCRs with same configuration information across all FCRs
in the fabrics.
To display the current broadcast zone configuration
1. Log in to the switch as admin.
2. Type the following command:
fcr:admin> fcrbcastconfig --show
This command displays only the FIDs that have the broadcast frame option disabled. The FIDs that are
not listed have the broadcast frame option enabled.
To enable the broadcast frame forwarding
1. Log in to the switch as admin.
2. Type the following command:
fcr:admin> fcrbcastconfig --enable -f <fabric id>
where <fabric id> is the specified FID where you want to enable frame forwarding. This feature is
turned on by default. This command enables the broadcast frame forwarding option for an FID (edge
fabric or backbone fabric).
To disable a broadcast zone forwarding
1. Log in to the switch as admin.
2. Type the following command:
fcr:admin> fcrbcastconfig --disable -f <fabric id>
where <fabric id> is the specified FID where you want to disable frame forwarding. This command
disables the broadcast frame forwarding option for an FID (edge or backbone fabric).
Upgrade and downgrade considerations
During a downgrade from v5.3.0 to a previous version, all the IPFC related configuration setting will be lost
and, since pre v5.3.0 releases do not support this feature, the IPFC flow across the FCR will be broken.
Monitoring resources
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 System Error Message
Reference Manual.
You can monitor 400 MP Router and 4/256 SAN Director resources using the fcrResourceShow
command. The fcrResourceShow command shows FCR resource limits and usage and includes:
• LSAN Zones and LSAN devices—The information shows the maximum versus the currently used zones
and device database entry. LSAN is the count of LSANs in all the edge fabrics. If they are defined in
two edge fabrics, they are counted as two and not one. One device imported into multiple edge fabrics
counts multiple times.
• Proxy Device Slots—The display shows the maximum versus the currently used proxy device slots. A
proxy device is presented to an edge fabric as being connected to a translate domain
slot . A slot is the
port number and AL_PA combination. The slot-to-device WWN association is persistently stored. The
physical and proxy devices use the 10000 device slots.
