FCIP tunnel configuration

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.
ATTENTION
In a multi-switch backbone fabric, modification of FID within the backbone fabric will cause
disruption to local traffic.
Assigning backbone fabric IDs
1. Log in to the switch or director.
2. Enter the switchDisable command if EX_Ports are online.
3. Enter the fosConfig
--disable fcr command to disable the FC-FC Routing Service.
The default state for the FCR is disabled.
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 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.
