CLI Command Updates and Changes Other options allow the collection of information on the reverse path or on a user-selected path (source route). For each hop, the routing information output includes the following: Hop The hop number, the local switch being hop 0. In Port Domain ID Name Out Port The port (or area) from which the frames come. For hop 0, the source port. For a switch with blades, this is specified as the area number; otherwise, as the port number. The domain ID of the switch. The name of the switch. The output port that the frames take to reach the next hop. For the last hop, the destination port or area. For a switch with blades, this is specified as the area number; otherwise, as the port number. BW The bandwidth of the output ISL, in gigabits per second. It does not apply to the embedded port. Cost The cost of the link used by FSPF routing protocol. It only applies to an E_Port. For each hop, statistics are broken down into basic and extended. They are reported below the routing information, separated into input port statistics and output port statistics. For each port, they are further separated into transmit and receive statistics. Statistics are not reported for the embedded port. Some values are measured over multiple time intervals. For example, the output line utilization in bytes per second is calculated over both a 1-second period and over a 64-second period. This gives an idea of both the current line utilization and the utilization over a longer period of time. The time interval is reported in parentheses, after the value's description. Maximum hop count The pathInfo command uses a special frame that is sent hop by hop from the source switch to the destination switch, collecting routing and statistics information at every hop. To prevent such a frame from looping forever if an error occurs, a maximum number of hops for the frame to traverse is enforced. 22 Fabric OS 3.1.3a Release Notes
