This routing information describes the full path that a data stream travels between these ports, including all intermediate switches. The routing and statistics information are provided by every switch along the path, based on the current routing-table information and statistics calculated continuously in real time. Each switch represents one hop. Use the pathInfo command to display routing information from a source port on the local switch to a destination port on another switch. The command output describes the exact data path between these ports, including all intermediate switches. When using this command in Fabric OS v6.2.0 across fabrics connected through an FC router, the command represents backbone information as a single hop. The command captures details about the FC router to which ingress and egress EX_Ports are connected, but it hides the details about the path the frame traverses from the ingress EX_Ports to the egress EX_Ports in the backbone. To use pathInfo across remote fabrics, you must specify both the fabric ID (FID) and the domain ID of the remote switch. You cannot use the command to obtain source port information across remote FCR fabrics. When obtaining path info across remote fabrics, the destination switch must be identified by its domain ID. Identifying the switch by name or WWN is not accepted. Use the pathInfo command in the following syntax: pathinfo destination_switch [source_port[destination_port]] [-r] [-t] Fabric OS Troubleshooting and Diagnostics Guide 17 53-1001187-01

Route and statistical information
The
pathInfo
command displays routing and statistical information from a source port index on the
local switch to a destination port index on another switch. This routing information describes the
full path that a data stream travels between these ports, including all intermediate switches.
The routing and statistics information are provided by every switch along the path, based on the
current routing-table information and statistics calculated continuously in real time. Each switch
represents one hop.
Use the
pathInfo
command to display routing information from a source port on the local switch to
a destination port on another switch. The command output describes the exact data path between
these ports, including all intermediate switches.
When using this command in Fabric OS v6.2.0 across fabrics connected through an FC router, the
command represents backbone information as a single hop. The command captures details about
the FC router to which ingress and egress EX_Ports are connected, but it hides the details about
the path the frame traverses from the ingress EX_Ports to the egress EX_Ports in the backbone.
To use pathInfo across remote fabrics, you must specify both the fabric ID (FID) and the domain ID
of the remote switch. You cannot use the command to obtain source port information across
remote FCR fabrics. When obtaining path info across remote fabrics, the destination switch must
be identified by its domain ID. Identifying the switch by name or WWN is not accepted.
Use the
pathInfo
command in the following syntax:
pathinfo
destination_switch
[
source_port
[
destination_port
]] [
-r
] [
-t
]
