pathInfo
22
destination_port
Specifies the port on the destination switch for the path being traced. This operand
returns the state of this port. The embedded port (-1) is used by default, or if you
specify a destination port that is not active. The destination is specified as the port
index.
"-r"
Displays the reverse path in addition to the forward path. This operand is optional.
-t
Displays the command output in traceroute format. When this operand is used,
only routing information is displayed. The output includes the time it takes, in
microseconds, to reach each hop. Basic and extended statistics are not available
in the traceroute format.
When executed without operands, pathInfo runs interactively. Specifying a destination switch is required;
the values for the source and destination ports can be -1 to indicate the embedded port. Reverse-path
tracing is optional. In addition, this command prompts for the following parameters:
max hops
The maximum number of hops that the pathInfo frame is allowed to traverse; the
default is 25.
Fabric Id
Specifies the Fabric ID. If unspecified, the value defaults to -1 (Default switch FID
128)
basic stats
Whether basic statistics are generated on every link; the default is no.
extended stats
Whether basic statistics are generated on every link; the default is no.
source route
Specifies a sequence of switches or ports that the pathInfo frame should traverse;
the default is no. If an output port to the next hop is specified, you are not
prompted for the domain of the next switch. The domain is determined by the port.
strict source rte
Specifies a strict source route, skipping intermediate switches. When using this
option, the source route hops must be specified using the domain rather than the
output port.
Timeout
The maximum time allowed waiting for the response in milliseconds. The default
is 10000 milliseconds.
EXAMPLES To display basic path information to a specific domain in command line mode:
switch:admin> pathinfo 91
