2 FC-FC routing connectivity • In frame redirection configurations, where there is a physical host, physical target, virtual initiator and virtual target; superping only identifies the path from the physical host to the physical target regardless if the data path consists of the path from physical target to virtual target through the virtual initiator. 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. ATTENTION Using the pathInfo command when exchange-based routing is turned on can provide different paths with each attempt. 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 v6.3.0 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 to display basic path information to a specific domain in command line mode: switch:admin> pathinfo 91 Target port is Embedded Hop In Port Domain ID (Name) Out Port BW Cost 0 E 9 (web226) 2 1G 1000 1 3 10 (web229) 8 1G 1000 2 8 8 (web228) 9 1G 1000 3 6 91 (web225) E - - To display basic and extended statistics in interactive mode: switch:admin> pathinfo Max hops: (1..127) [25] Fabric Id: (1..128) [-1] Domain|Wwn|Name: [] 8 Source port: (0..15) [-1] Destination port: (0..255) [-1] Basic stats (yes, y, no, n): [no] y Extended stats (yes, y, no, n): [no] y Trace reverse path (yes, y, no, n): [no] Source route (yes, y, no, n): [no] 20 Fabric OS Troubleshooting and Diagnostics Guide 53-1001769-01

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.

Using the
pathInfo
command when exchange-based routing is turned on can provide different paths
with each attempt.
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.
