Description
Use this command to display the fabric topology, as it appears to the local switch.
This includes:
•
A list of all domains that are part of the fabric, and to each of those domains, all possible paths
from the local switch.
•
For each path - cost, the number of hops from the local switch to the destination switch, name
of the destination switch, and a summary of all ports are routed through that path.
A path is described by the output port that a frame addressed to a certain domain will be forwarded
to by the switches' routing hardware, in order to reach the domain.
With the domain number specified, this command displays the topology information for the
specified destination domain.
The display contains the following fields:
Local Domain ID:
Domain:
Metric:
Hops:
Out Port:
In Ports:
Flags:
Name:

This command has the following operand:
domainnumber
Fabric OS Reference
Domain number of local switch.
Domain number of destination switch.
Cost of reaching destination domain.
The maximum number of hops to reach destination domain.
Port that incoming frame will be forwarded to, in order to reach the destination
domain.
Bit map of input ports to use the corresponding Out Port to reach the destination
domain. A bit set to 1 indicates port is being routed through the corresponding
Out Port. The least significant bit represents port 0. This is the same information
provided in a different format by portRouteShow and uRouteShow.
Always 'D', indicating a dynamic path. A dynamic path is discovered
automatically by the FSPF path selection protocol.
Name of destination switch.
Specify the destination domain for which topology information is to be
displayed. This operand is optional.
