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 The maximum number of hops that the pathinfo frame is allowed to traverse. Domain The destination Domain ID. Source Port The port number (or area number for 4/256 SAN Director) on which the switch receives frames. Destination Port The output port the frames use to reach the next hop on this path. For the last hop, the destination port. Basic stats Basic statistics on every link. Extended stats Detailed statistics on every link. Trace reverse path Whether the same path should be followed from the destination switch back to the source switches. 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 - - switch.admin> 208 Routing traffic
