4. Enter the fcrConfigure command. At the prompt, enter the fabric ID, or press Enter to keep the
current fabric ID, which is displayed in brackets.
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. Enter the fosConfig
--enable fcr command.
7. Enter th e switchEnable command.
Example
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
Please make sure new Backbone Fabric ID does not conflict with any configured
EX-Port's Fabric ID
Backbone fabric ID: (1-128)[128]
switch:admin> fosconfig --enable fcr
FC Router service is enabled
switch:admin> switchenable
FCIP tunnel configuration
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 only using FC_Ports, then
there is no need to perform this step.
If 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 the Fibre Channel over IP Administrator’s Guide for instructions on how to configure FCIP
tunnels.
Inter-fabric link configuration
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 inter-fabric link involves disabling ports and cabling them to other fabrics,
configuring those ports for their intended use, and then enabling the ports.
To configure a 16-Gbps IFL, both the EX_Port and the connecting E_Port must be 16-Gbps ports.
