Viewing routing information along a path You can 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 full path that a data stream travels between these ports, including all intermediate switches. 1. Connect to the switch and log in as admin. 2. Enter the pathInfo command. In interactive mode, you can specify the following parameters for display: Max hops Domain Source Port Destination Port Basic stats Extended The maximum number of hops that the pathinfo frame is allowed to traverse. The destination domain ID. You must specify a value between 1 and 239. The port number (or area number for enterprise-class platforms) on which the switch receives frames. The output port the frames use to reach the next hop on this path. For the last hop, the destination port. Basic statistics on every link. Detailed statistics on every link. stats Trace reverse Whether the same path should be followed from the destination switch path back to the source switch. Source route Whether the frame should follow a specified path to reach the destination. Timeout The maximum time to wait for a response from pathInfo, in seconds. Paths always originate on the local switch. The path destination can be specified by domain or port. By default, the path will be the path taken by traffic from the source to destination port, but you can also specify all or portions of a path. See the Fabric OS Command Reference for details on the pathInfo command. Following is an example of pathInfo in interactive mode. switch:admin> pathinfo Max hops: (1..127) [25] Domain: (1..239) [-1] 1 Source port: (0..255) [-1] Destination port: (0..255) [-1] Basic stats (yes, y, no, n): [no] Extended stats (yes, y, no, n): [no] Trace reverse path (yes, y, no, n): [no] Source route (yes, y, no, n): [no] Timeout: (1..30) [10] Target port is Embedded Hop In Port Domain ID (Name) Out Port BW Cost 0 E 10 (web226) 15 2G 500 1 7 1 (web229) E - - 238 Routing traffic
