320 Using the FC-FC routing service
IMPORTANT: In a multi-switch backbone fabric, modification of FID within the backbone fabric causes
disruption to local traffic.
To assign backbone fabric IDs:
1. Log in to the switch or director.
2. Issue the switchDisable command.
3. Issue the fosConfig --disable fcr command to disable the FC-FC Routing Service. See the
Fabric OS Command Reference or the CLI man pages for more information about the fosConfig
command.
The default state for the FCR is disabled.
4. Issue the fcrConfigure command. At the prompt, issue the fabric ID, or press Enter to specify the
default fabric ID (1).
5. Verify the backbone 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.
6. Issue the fosConfig
--enable command.
7. Issue the switchEnable command.
switch:admin> switchdisable
switch:admin> fosconfig --disable fcr
FC Router service is disabled
switch:admin> fcrconfigure
FC Router parameter set. <cr> to skip a parameter
Backbone fabric ID: (1-128)[1]
switch:admin> fosconfig --enable fcr
FC Router service is enabled

Configuring FCIP tunnels
The optional Fibre Channel over IP (FCIP) Tunneling Service enables you to use “tunnels” to connect
instances of Fibre Channel SANs over IP-based networks to transport all Fibre Channel ISL and IFL traffic.
FCIP is a prerequisite for configuring VEX_Ports; if you are using only FC_Ports, there is no need to perform
this step.
If you are using FCIP in your FC-FC Routing configuration, you must first configure FCIP tunnels. Once a
tunnel is created, it defaults to a disabled state. Then configure the VE_Port or VEX_Port. After the
appropriate ports are configured, enable the tunnel.
NOTE: This section is applicable only to Fabric OS fabrics and does not apply to M-EOS fabrics.
See ”Configuring and monitoring FCIP extension services” on page 385 for instructions on how to
configure FCIP tunnels.
Configuring an interfabric link
Before configuring an IFL, be aware that you cannot configure both IFLs (EX_Ports, VEX_Ports) and ISLs
(E_Ports) from a backbone fabric to the same edge fabric.
Configuring an interfabric link involves disabling ports and cabling them to other fabrics, configuring those
ports for their intended use, and then enabling the ports.
To configure an 8-Gbps IFL, both the EX_Port and the connecting E_Port must be 8-Gbps ports.
