Source route
The source route option allows the user to specify a sequence of switches or ports
(or areas) that the pathInfo frame has to follow to reach the destination.
Therefore, the path might be different from the one the actual traffic from source
to destination will take.
The source route is expressed as a sequence of switches, a sequence of output
ports (or areas), or a combination thereof. The next hop in the source route is
described by either the output port (or area) to be used to reach the hop or the
domain ID of the next hop.
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 you to specify a strict path 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 the 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/areas.
Operands
The following operands are allowed:
domain The ID of the destination domain.
source port The port (or area) whose path to the destination
domain is sought. The embedded port (-1) is used
by default. For a switch with blades, the
destination is specified as the area; otherwise, as
the port. If the source port is given as -1 with no
additional arguments, then basic statistics will be
displayed for the route.
