trunkShow 2 trunkShow Displays trunking information. SYNOPSIS trunkshow [-perf] DESCRIPTION Use this command to display trunking information of both E_Ports and EX_Ports. The command displays the following fields: Trunking Group Number Displays each trunking group on a switch. All ports that are part of this trunking group are displayed. Port to port connections Displays the port-to-port trunking connections. WWN Displays the world wide name of the connected port. Domain Displays the domain IDs of the switches directly connected to the physical ports. In case of an FC Router backbone fabric interlinking several edge fabrics, the domain ID displayed for an E_Port trunk refers to a domain of a switch within the backbone fabric, whereas the domain ID displayed for an EX_Port trunk refers to the domain ID of a switch in the edge fabric. Because they are independent fabrics, it is possible that both the backbone and the edge fabric may have the same domain ID assigned to switches. If this is the case, run switchShow to obtain information on the port types of the local switch and the WWNs of the remote switches. Refer to the Example section for an illustration. deskew The difference between the time it takes for traffic to travel over each ISL compared to the time it takes through the shortest ISL in the group plus the minimum deskew value. The value is expressed in nanoseconds divided by 10. The firmware automatically sets the minimum deskew value for the shortest ISL, which is 15. Master Displays whether this trunking port connection is the master port connection for the trunking group. When used with the -perf option, the command output displays the following additional information: bandwidth The bandwidth (Rx, Tx, and the combined total for Tx+Rx) of the trunk group. Values are displayed as either bits per second (Bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps), rounded down to the next integer. throughput Displays the throughput (Rx, Tx, and the combined total for Tx+Rx) of the trunk group. Results are displayed for the previous second. Values are displayed as either bits per second (Bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps), rounded down to the next integer. % Displays the percentage of link utilization (Rx, Tx, and the combined total for Tx+Rx) . Even when the link utilization is 100% , the throughput value will be lesser than the bandwidth value, due to the 8b/10b encoding and the control words transmitted. For example, the throughput for an 8Gbps link at 100% utilization would be approximately 6.8Gbps. Fabric OS Command Reference 53-1002746-01 1067
