Displays routing and statistics information along a path.
Syntax
pathinfo [[[domain], source port], destination port] [,"-r"]
Availability
Admin
Description
Use this command to 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 exact path that a user data stream takes to go from the source to the destination. If
the user specifies the use of inactive ports or a path through a switch that does not have active
routing tables to the destination, pathinfo describes the path that is used if the ports were
active. If the user specifies a destination port that is not active, pathinfo uses the embedded
port as the destination.
For switches with blades, the ingress and egress points are specified as area numbers. For a
nonbladed switch, ingress and egress points are specified as ports. This agrees with the
representation in the
switchshow
command.
In addition, pathinfo can provide, upon request, statistics on every traversed ISL.
Routing and statistics information is provided by every switch along the path, based on the
current routing tables and statistics calculated continuously in realtime. Each switch represents
one hop.
Other options allow the collection of information on the reverse path or on a user-selected path
(source route).
For each hop, the routing information output consists of the following:
pathinfo
Hop
The hop number; the local switch is hop 0.
In Port
The port (or area) from which the frames come. For hop
0, the source port. For a switch with blades, this is
specified as the area number; otherwise, it is the port
number.
Domain ID
The domain ID of the switch.
Name
The name of the switch.
Out Port
The output port that the frames take to reach the next
hop. For the last hop, the destination port or area. For a
switch with blades, this is specified as the area number;
otherwise, it is the port number.
BW
The bandwidth of the output ISL, in Gbit/sec. It does
not apply to the embedded port.
Cost
The cost of the link used by FSPF routing protocol. It
applies only to an E_Port.
