Fabric OS reference guide pathinfo Syntax Availability Description 184 Displays routing and statistics information along a path. pathinfo [[[domain], source port], destination port] [,"-r"] Admin Use this command to display detailed routing information from a source port (or area) on the local switch to a destination port (or area) on another switch. This routing information describes the exact path that a user data stream takes to go from the source to the destination. If the user specifies the use of inactive ports or a path through a switch that does not have active routing tables to the destination, pathinfo describes the path that is used if the ports were active. If the user specifies a destination port that is not active, pathinfo uses the embedded port as the destination. For switches with blades, the ingress and egress points are specified as area numbers. For a nonbladed switch, ingress and egress points are specified as ports. This agrees with the representation in the switchshow command. In addition, pathinfo can provide, upon request, statistics on every traversed ISL. Routing and statistics information is provided by every switch along the path, based on the current routing tables and statistics calculated continuously in realtime. Each switch represents one hop. Other options allow the collection of information on the reverse path or on a user-selected path (source route). For each hop, the routing information output consists of the following: Hop In Port The hop number; the local switch is hop 0. The port (or area) from which the frames come. For hop 0, the source port. For a switch with blades, this is specified as the area number; otherwise, it is the port number. Domain ID The domain ID of the switch. Name The name of the switch. Out Port BW Cost The output port that the frames take to reach the next hop. For the last hop, the destination port or area. For a switch with blades, this is specified as the area number; otherwise, it is the port number. The bandwidth of the output ISL, in Gbit/sec. It does not apply to the embedded port. The cost of the link used by FSPF routing protocol. It applies only to an E_Port. Fabric OS 3.x Document Addendum
