pathInfo
Switches running pre-v5.2 firmware cannot use port numbers greater than 256 as a destination
port on a remote switch.
Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
Operands The following operands are optional:
domain
src_portnumber
dst_portnumber
"-r"
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 the following
parameters:
max hops
basic stats
extended stats
source route
384
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 are
ignored. In case of a loose source route, the switches in-between are
reported. The concepts of strict and loose route apply to the portions of the
path described by domains, not to the part described by output ports or
areas.
ID of the destination domain. If this operand is omitted, the command
prompts for all operands, including whether basic and extended statistics
should be provided.
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.
Port or area on the destination switch for each path being traced. This
operand 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.
Display the reverse path in addition to the forward path.
The maximum number of hops that the pathInfo frame is allowed to traverse;
default is 25.
Requests the reporting of basic statistics on every link; default is no.
Requests the reporting of extended statistics on every link; default is no.
Specifies a sequence of switches or ports that the pathInfo frame should
traverse; the default is no. Note that if an output port (or area) to the next hop
is specified, you are not prompted for the domain of the next switch, which is
determined by the port (or area) specified.
