CLI Command Updates and Changes
22 Fabric OS 3.1.3a Release Notes
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 includes the following:
For each hop, statistics are broken down into basic and extended. They are
reported below the routing information, separated into input port statistics and
output port statistics. For each port, they are further separated into transmit and
receive statistics. Statistics are not reported for the embedded port.
Some values are measured over multiple time intervals. For example, the output
line utilization in bytes per second is calculated over both a 1-second period and
over a 64-second period. This gives an idea of both the current line utilization and
the utilization over a longer period of time. The time interval is reported in
parentheses, after the value's description.
Maximum hop count
The pathInfo command uses a special frame that is sent hop by hop from the
source switch to the destination switch, collecting routing and statistics
information at every hop. To prevent such a frame from looping forever if an error
occurs, a maximum number of hops for the frame to traverse is enforced.
Hop The hop number, the local switch being 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, as 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, as the
port number.
BW The bandwidth of the output ISL, in gigabits
per second. It does not apply to the embedded
port.
Cost The cost of the link used by FSPF routing
protocol. It only applies to an E_Port.
