pathInfo 2 Operands The source route can specify a partial route from source to destination (in which case the remaining hops are chosen as the path from the input port or area on the first hop not listed in the source route to the destination), as a full route, or as an arbitrary route across the fabric. The maximum hop count is enforced. If the source route does not specify all the switches along a section of the path, a further option allows to specify a strict versus a loose path. A strict source route requires that only the specified switches are reported in the path description. If two switches are specified back to back in the source route descriptor, but are not directly connected, the switches in between will be ignored. In case of a loose source route, the switches in between will be reported. The concepts of strict and loose route apply to the portion(s) of the path described by domains, not to the part described by output ports or areas. Switches running pre 5.2 firmware cannot use ports > 256 as a destination port on a remote switch. The execution of this command is subject to Admin Domain restrictions that may be in place. The following operands are optional: domain ID of the destination domain. The command is optional. If omitted, the command prompts for all operands, including whether basic and extended statistics should be included. src_portnumber Port or area whose path to the destination domain is sought. The default is embedded port (-1). For bladed systems, the destination is specified as the area; otherwise, it is the port. If the source port is -1 with no additional arguments, basic statistics display for the route. dst_portnumber Port or area on the destination switch for each path being traced. This command returns the state of this port or area. The default is embedded port (-1), or if a destination port is specified that is not active. For bladed systems, the destination is specified as the area; otherwise, it is the port. "-r" Display reverse path in addition to forward path. Without operands, pathInfo prompts for the preceding operands. The value of domain is mandatory; the values for the source and destination ports can be -1, to indicate the embedded port. Reverse-path tracing remains optional. In addition, this command prompts for following parameters: max hops The maximum number of hops that the pathInfo frame is allowed to traverse; default is 25. basic stats Requests the reporting of basic statistics on every link; default is no. extended stats Requests the reporting of extended statistics on every link; default is no. source route Specifies a sequence of switches or ports that the pathInfo frame should traverse; default is no. Note that if an output port (or area) to the next hop is specified, the user is not prompted for the domain of the next switch, which is determined by the port (or area) specified. Default: No. strict source rte Specifies that the source route must be followed strictly as indicated, skipping possible intermediate switches. When using this option, the source route hops must be specified using domain rather than output port. Fabric OS Command Reference Manual 401 53-1000436-01
