2 topologyShow 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. 1058 Fabric OS Command Reference 53-1002746-01
