Viewing Routing Information Along A Path - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Viewing routing information along a path

You can 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 full path that a data
stream travels between these ports, including all intermediate switches.
1. Connect to the switch and log in as admin.
2. Enter the pathInfo command. In interactive mode, you can specify the following parameters for
display:
Max hops
Domain
Source Port
Destination Port
Basic stats
Extended stats
Trace reverse path
Source route
Timeout
Paths always originate on the local switch. The path destination can be specified by domain or port. By
default, the path will be 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 Fabric OS Command Reference Manual for details on the pathInfo command.
The following example is from a SAN Switch 2/32 switch (other models provide similar information):
switch:admin> pathinfo
Max hops: (1..127) [25]
Domain: (1..239) [-1] 1
Source port: (0..255) [-1]
Destination port: (0..255) [-1]
Basic stats (yes, y, no, n): [no]
Extended stats (yes, y, no, n): [no]
Trace reverse path (yes, y, no, n): [no]
Source route (yes, y, no, n): [no]
Timeout: (1..30) [10]
