HP StorageWorks 2/64 - Core Switch Command Reference Manual page 390

Operands
The following operands are optional:
domain
src_portnumber
dst_portnumber
"-r"
Without operands,
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
basic stats
extended stats
source route
strict source rte
Timeout
390 Fabric OS commands
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 portions of the path described by domains,
not to the part described by output ports or areas.
ID of the destination domain. If omitted, the command prompts
for all operands, including whether basic and extended statistics
should be included.
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 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.
Display reverse path in addition to forward path.
prompts for the preceding operands. The value of domain is mandatory;
pathInfo
The maximum number of hops that the
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
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.
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.
The maximum time allowed to wait for the response; default is
10 seconds.
