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
interfabric 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 interfabric 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 entries 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 specified
by the “Destination Fabric ID” column. This is useful to correlate the fabric ID
listed in the “Destination Fabric ID” column with the actual fabric.
