208 Using the FC-FC routing service

Enter the

secModeShow

command to verify that security is disabled.

Enter the

msPlatShow

command to verify that Management Server Platform database is disabled in

the backbone fabric.

If any of the items listed in the prior steps are enabled, you can see the Fabric OS Command Reference

Manual for information on how to disable the option. For information about security, see ”

Configuring

standard security features

” on page 83 and ”

Configuring advanced security

” on page 133.

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.

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 Manual

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 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 FID 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 RAS log

message is displayed 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.

To assign backbone fabric IDs

Enter the

fosConfig

--disable fcr

command to disable the FC-FC Routing Service. See the

Fabric OS Command Reference Manual or the CLI man pages for more information about the

fosConfig

command.

NOTE:

The default state for the FCR is disabled. The

fcrEnable

and

fcrDisable

commands continue

to operate as before, however

fosConfig

is the preferred method for enabling and disabling the FC-FC

Routing (FCR) Service.

Enter the

fcrConfigure

command. At the prompt, enter the fabric ID, or press

Enter

to specify the

default fabric ID (1).

Verify that the fabric ID is different from that set for edge fabrics.
Multiple FC routers attached to the same backbone fabric must have the same backbone fabric ID.
