topologyShow
Displays the unicast fabric topology.
SYNOPSIS
topologyshow [ domain ]
DESCRIPTION
Use this command to display the fabric topology as it appears to the local switch. The display varies
depending on the hardware configuration. The following rules apply:
•
On all switches, the command displays the number of domains in the fabric and the local Domain
IDs. If translate domains are configured, existing translate domains and associated ports are
displayed.
•
On an edge fabric, the command displays the following additional details for all domains in the fabric
(including local translate domains):
-
All possible paths from the local switch to each of the remote domains.
-
For each path, the cost, the associated output port on the local switch, the path cost, and the
number of hops from the local switch to the destination switch.
-
A summary of all ports that are routed through that path.
•
On a backbone fabric, the command displays details for remote domains only. Details for local
translate domains are not displayed.
•
If there are two switches in the Backbone and the edge fabric is directly connected to both of those
switches,
topologyshow does not display the description of the translate domain associated with
that edge fabric. In this case the translate domain is considered local to both of the switches in the
backbone.
•
If there is only one switch in the backbone, no domain details are displayed (all domains are local).
Depending on the fabric, the display may contains the following fields:
Local Domain ID
The domain number of local switch.
Local Translate Domain x owned by port
The port number associated with the local translate domain x .
Domain
The domain number of destination switch.
Metric
The cost of reaching destination domain.
Name
The name of the destination switch.
Path Count
The number of currently active paths to the destination domain.
Hops
The maximum number of hops to reach destination domain.
Out Port
The port to which incoming frames are forwarded to reach the destination domain.
In Ports
The input ports that use the corresponding out port to reach the destination
domain. This is the same information provided by
portRouteShow and
uRouteShow but in a different format.
