User Manual

Fabric OS 5.0.0 procedures user guide 105
Paths always originate on the local switch. The path destination can be specified by domain or port. By
default, the path is the path taken by traffic from the source to destination port, but you can also specify all
or portions of a path.
Refer to the HP StorageWorks Fabric OS 4.x command reference guide for details on this command.
The following example is from a SAN Switch 2/32 (other models provide similar information):
The information that pathinfo provides is:
• Extended stats Detailed statistics on every link
• Trace reverse path The path from the destination switch back to the source switches
• Source route The route that the frame is forced to follow a specified path to reach
the destination
• Timeout The maximum time to wait for a response from pathinfo, in seconds

• Hop The hop number. The local switch is hop 0.
• In Port The port that the frames come in from on this path. For hop 0, the source port.
• Domain ID The domain ID of the switch.
• Name The name of the switch.
• Out Port The output port that the frames use to reach the next hop on this path. For the
last hop, the destination port.
• BW The bandwidth of the output ISL, in Gbps. It does not apply to the
embedded port.
• Cost The cost of the ISL used by FSPF routing protocol. It applies only to an E_Port.
