fcrRouteShow

Displays FC Router route information.

Synopsis

fcrrouteshow

Description

Use this command to display routes through the FC Router backbone fabric to accessible
destination fabrics. An FC Router backbone fabric is the fabric that contains the E_Ports of this
platform and routes inter-fabric traffic between imported fabrics, creating a meta-SAN.

There are FC Router ports that reside on the backbone fabric. These ports are known as NR_Ports.
NR_Ports send and receive inter-fabric traffic. For the AP7420, there is a one-to-one relationship
between an NR_Port on a backbone fabric and an EX_Port. NR_Port technology enables EX_Ports
to exchange traffic across an intermediate fabric. NR_Ports are addressable entities on the
backbone fabric and have port IDs relevant to the backbone fabric.

Because cascaded backbone/intermediate fabrics are currently not supported, an NR_Port
provides a path to a single fabric with a single FC Router protocol cost. Multiple NR_Ports can
provide paths to the same destination fabric.

“No routes found” is displayed if there is no route information available at this FC Router. There is
no route information available if no EX_Ports are configured at this FC Router.

The output includes:

Destination Fabric ID

The destination fabric.

NR_Port PID

The port ID of the NR_Port. The port ID is relevant only on the backbone
fabric. This NR_Port has a route to the destination fabric identified by the
“Destination Fabric ID” column.

FCRP Cost

The FC Router protocol cost (for routing decisions) for this NR_Port. The FCRP
cost is the same (1000) for all NR_Ports.

WWN of the Principal Switch in the Dest. Fabric

The world wide name of the principal switch in the destination fabric.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
