FC-FC Routing connectivity 2 Example of one device that accepts the request and another device that rejects the request: switch:admin> fcping 10:00:00:00:c9:29:0e:c4 21:00:00:20:37:25:ad:05 Source: 10:00:00:00:c9:29:0e:c4 Destination: 21:00:00:20:37:25:ad:05 Zone Check: Not Zoned Pinging 10:00:00:00:c9:29:0e:c4 [0x20800] with 12 bytes of data: received reply from 10:00:00:00:c9:29:0e:c4: 12 bytes time:1162 usec received reply from 10:00:00:00:c9:29:0e:c4: 12 bytes time:1013 usec received reply from 10:00:00:00:c9:29:0e:c4: 12 bytes time:1442 usec received reply from 10:00:00:00:c9:29:0e:c4: 12 bytes time:1052 usec received reply from 10:00:00:00:c9:29:0e:c4: 12 bytes time:1012 usec 5 frames sent, 5 frames received, 0 frames rejected, 0 frames timeout Round-trip min/avg/max = 1012/1136/1442 usec Pinging 21:00:00:20:37:25:ad:05 [0x211e8] with 12 bytes of data: Request rejected Request rejected Request rejected Request rejected Request rejected 5 frames sent, 0 frames received, 5 frames rejected, 0 frames timeout Round-trip min/avg/max = 0/0/0 usec Example To use fcPing with a single destination (in this example, the destination is a device node WWN): switch:admin> fcping 20:00:00:00:c9:3f:7c:b8 Destination: 20:00:00:00:c9:3f:7c:b8 Pinging 20:00:00:00:c9:3f:7c:b8 [0x370501] with 12 bytes of data: received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:825 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:713 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:714 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:741 usec received reply from 20:00:00:00:c9:3f:7c:b8: 12 bytes time:880 usec 5 frames sent, 5 frames received, 0 frames rejected, 0 frames timeout Round-trip min/avg/max = 713/774/880 usec 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.
