Integrated Routing license
If you are connecting to a Fabric OS or M-EOS fabric and the Integrated Routing license is not
installed, you must install it, as described in
Chapter 18, “Administering Licensing” . The
Integrated Routing license is not required if you are connecting to a Brocade Network OS fabric.
4. Verify that the Fabric-Wide Consistency Policy is not in “strict” mode by issuing the fddCfg
-- showall command. When it is in strict mode, ACL cannot support Fibre Channel routing in the
fabric.
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 letter “S” in it in the edge fabric or the backbone
fabric, do not connect the edge fabric to the FC router. The letter “S” (shown in the preceding
sample output) indicates the policy is strict. The fabric-wide policy must be tolerant before you
can connect fabrics to the FC router. Refer to
Chapter 7, “Configuring Security Policies” for
information about configuring the fabric-wide consistency policy.
5. For 8-Gbps platforms, delete fabric mode Top Talker monitors, if they are configured. Refer to
“Deleting all fabric mode Top Talker monitors” on page 515 for instructions.
FC-FC routing and fabric mode Top Talker monitors are not concurrently supported on 8-Gbps
platforms.
FC-FC routing and fabric mode Top Talker monitors are concurrently supported only on the
Brocade 6510 and 6520 switches, and on the Brocade DCX Backbone family with only
16-Gbps-capable ports.
Backbone fabric IDs
If your configuration has only one backbone fabric, then you do not need to assign a backbone
fabric ID because the backbone fabric ID in this situation defaults to a value of 128. The default
backbone fabric ID is 1 if Virtual Fabrics is disabled.
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 must 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
must 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. When two backbone
fabrics are not connected to the same edge, they can have the same backbone fabric ID.
