fcrConfigure
Displays or sets FC Router configuration parameters.
SYNOPSIS
fcrconfigure --bbfid
fcrconfigure --enable -shortestifl
fcrconfigure --disable -shortestifl
fcrconfigure --add -alias Alias_name -fid FID
fcrconfigure --delete -alias [FID | -all]
fcrconfigure --show [-alias]
fcrconfigure --help
DESCRIPTION
Use this command to change the backbone fabric ID, or to enable or disable the shortest inter-fabric link
(IFL) mode. If no operands are specified, this command displays the usage. Use the --show option to
display the current settings on the switch.
Before you configure the backbone fabric ID using the --bbfid option, you must disable FC routing by
using the fosConfig command and disable the switch using the switchDisable command.
NOTES
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
--bbfid
Specifies the Backbone Fabric ID. This is an interactive option. A fabric ID
uniquely identifies a fabric in FC Router configurations. The backbone fabric is the
fabric attached to the U_Ports of the switch, for example, E_Ports or F_Ports. The
backbone fabric ID must be unique across all fabrics connected to the FC Router.
Use the switchShow command to display the current Backbone Fabric ID.
--enable -shortestifl
Enables the shortest IFL mode in FC Router.
When the shortest IFL mode is enabled, FC Router can choose a lowest-cost IFL
path in the backbone fabric. This feature is useful when an FC Router has multiple
connections to the source edge fabric and the backbone fabric has multiple FC
Routers connected through FCIP links (VE_Ports) and FC links (E_Ports).
Because a domain in an edge fabric can choose any equal cost path to reach the
translate domain, frames can be transmitted through FCIP links even though FC
links are present in the backbone fabric. When the shortest IFL mode is enabled,
the FCIP path in the backbone fabric is avoided while reaching the destination
edge fabric.
You should identify the FCIP links in the backbone fabric and then the direction of
the FCIP path (across the backbone fabric) from the source to the destination
edge fabric. Once the direction of the FCIP path is identified, set the cost of the
FCIP link greater than or equal to 10000 by using the linkCost command. The link
cost must be set for all FC Routers in the identified FCIP link path. Likewise,
identify and set the cost for other FCIP paths of all destination edge fabrics.
