show fabric route pathinfo
Displays the path of a data stream through a fabric and provides statistics about each hop on that
path.

Operands You are prompted to select parameters interactively. The command will prompt you for the
following parameters:
Fabric ID Enter the VCS ID of the destination Network OS switch or the Fabric ID of
the destination Fabric OS switch. If unspecified, the value defaults to
− 1,
which specifies the Brocade VCS Fabric cluster of the local switch.
Domain Enter the RBridge ID of the destination Network OS switch or the domain ID
of the destination Fabric OS switch. You must enter a value for this
parameter. It has no default value.
Source Port Enter the port index of the port at the head of the data stream to be traced.
traced. If unspecified, the value defaults to
− 1, which specifies the
embedded port.
Destination Port Enter the port index of the port on the destination switch for the path being
traced. If unspecified, the value defaults to
− 1, which specifies the
embedded port. The command output also reports the status of the
Destination Port. If the specified port is out of range on the destination
switch, the command fails with the message “Target port not present.”
Basic Stats Enter y to display basic statistics about each hop. By default, basis
statistics are not displayed.
Extended Stats Enter y to display extended statistics about each hop. By default, extended
statistics are not displayed.
Reverse Path Enter y to display reverse path information in addition to the forward path
information. By default, reverse path information is not displayed.
The path from port A on switch X to port B on switch Y might be different
from the path from port B to port A depending on the links traversed
between a given sequence of switches, or the reverse path might involve
different switches.
Defaults This command has no inherent defaults. Refer to the Description for parameter-specific defaults.
Command Modes Privileged EXEC mode
Description Use this command to display detailed routing information and statistics for a data stream from a
source port on the local switch to a destination port on another switch. The destination switch can
be a member of the same Brocade VCS Fabric cluster, a member of a different Brocade VCS Fabric
cluster, a member of a Fabric OS backbone fabric, or a member of a Fabric OS edge fabric. This
routing information describes the exact path that a user data stream takes to go from the source
port to the destination port.
Use this command to check whether a congested link might be causing performance degradation
on a specific data stream or path.
