See the Fabric OS Command Reference for details. Assigning backbone fabric IDs If your configuration has only one backbone fabric, then this task is not required because the backbone fabric ID in this situation defaults to a value of 1. All switches in a backbone fabric must have the same backbone fabric ID. You can configure the backbone fabric ID using the fcrConfigure command. The backbone fabric ID is required to be unique from the perspective of every attached edge fabric. Fabric ID changes made on a switch are not propagated to other switches in the backbone fabric. Rather, the backbone fabric administrator is responsible for making sure that all switches in the backbone have the same fabric ID. Because fabric IDs are used heavily by the routing protocol between the Fibre Channel routers, using the wrong fabric ID can affect both edge-to-edge and backbone-to-edge routing. In addition to ensuring that the backbone fabric IDs are the same within the same backbone, you need to make sure that when two different backbones are connected to the same edge fabric, the backbone fabric IDs are different, but the edge fabric ID should be the same. Configuration of two backbones with the same backbone fabric ID that are connected to the same edge is invalid. In this configuration, a RASLog message displays a warning about fabric ID overlap. However, when two backbone fabrics are not connected to the same edge, they can have the same backbone fabric ID. IMPORTANT: In a multi-switch backbone fabric, modification of FID within the backbone fabric will cause disruption to local traffic. 302 Using the FC-FC Routing Service

Enter the

If any of the items listed in the prior steps are enabled, you can see the

When it is in strict mode, ACL cannot support Fibre Channel routing in the fabric. Before connecting an
edge fabric to an FC router and before setting up the FC router in the BB, verify that the Fabric Wide
Consistency Policy is not in ‘strict’ mode by issuing the
fddCfg
--
showall
command.
switch:admin> fddcfg --showall
Local Switch Configuration for all Databases:-
DATABASE - Accept/Reject
---------------------------------------
SCC - accept
DCC - accept
PWD - accept
Fabric-Wide Consistency Policy :- "SCC:S;DCC"
If the Fabric Wide Consistency Policy has the ‘S’ letter in it in the edge fabric or the BB fabric, do not
connect the edge fabric or the BB to the FC router. See the
Fabric OS Command Reference
for details.
Assigning backbone fabric IDs
If your configuration has only one backbone fabric, then this task is not required because the backbone
fabric ID in this situation defaults to a value of 1.
All switches in a backbone fabric must have the same backbone fabric ID. You can configure the backbone
fabric ID using the
fcrConfigure
command. The backbone fabric ID is required to be unique from the
perspective of every attached edge fabric. Fabric ID changes made on a switch are not propagated to
other switches in the backbone fabric. Rather, the backbone fabric administrator is responsible for making
sure that all switches in the backbone have the same fabric ID. Because fabric IDs are used heavily by the
routing protocol between the Fibre Channel routers, using the wrong fabric ID can affect both
edge-to-edge and backbone-to-edge routing.
In addition to ensuring that the backbone fabric IDs are the same within the same backbone, you need to
make sure that when two different backbones are connected to the same edge fabric, the backbone fabric
IDs are different, but the edge fabric ID should be the same. Configuration of two backbones with the same
backbone fabric ID that are connected to the same edge is invalid. In this configuration, a RASLog
message displays a warning about fabric ID overlap. However, when two backbone fabrics are not
connected to the same edge, they can have the same backbone fabric ID.
IMPORTANT:
In a multi-switch backbone fabric, modification of FID within the backbone fabric will cause
disruption to local traffic.
