The following example sets the speed for all ports on the switch to 8 Gb/s: switch:admin> switchcfgspeed 8 Committing configuration...done. The following example sets the speed for all ports on the switch to autonegotiate: switch:admin> switchcfgspeed 0 Committing configuration...done. Displaying trunking information You can display all the trunks and members of a trunk, and whether the trunking port connection is the master port connection for the trunking group. Viewing trunks is also useful for when you want to ensure that trunks are formed correctly. Use the trunkShow command to display the following information about ISL Trunking groups: Trunking Group Number Port-to-port connections, WWN Domain Each trunking group on a switch. All the ports that are part of this trunking group are displayed. The port-to-port trunking connections. The WWN of the connected port. The domain IDs of the switches directly connected to the physical ports. Deskew The time difference, in nanoseconds divided by 10, for traffic to travel over each ISL as compared to the shortest ISL in the group. The system automatically sets the minimum deskew value of the shortest ISL to 15. Master Whether this trunking port connection is the master port connection for the trunking group. 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the trunkShow command. This example shows three trunking groups (1, 2, and 3); ports 1, 4, and 14 are masters: switch:admin> trunkshow 1: 1 -> 1 10:00:00:60:69:04:10:83 0 -> 0 10:00:00:60:69:04:10:83 2: 4 -> 4 10:00:00:60:69:04:01:94 5 -> 5 10:00:00:60:69:04:01:94 7 -> 7 10:00:00:60:69:04:01:94 6 -> 6 10:00:00:60:69:04:01:94 3:14 -> 14 10:00:00:60:69:04:10:83 15 -> 15 10:00:00:60:69:04:10:83 Trunking over extended fabrics deskew 16 Master deskew 15 deskew 16 Master deskew 15 deskew 17 deskew 16 deskew 16 Master deskew 15 In addition to the criteria listed in "Standard trunking criteria" on page 436, observe the following criteria for trunking over extended fabrics: • It is supported on switches running Fabric OS 4.4.0 and later. • Extended Fabrics and ISL Trunking licenses are required on all participating switches. • When configuring long distance, the portCfgLongDistance --vc_translation_link_init parameter must be set the same on all ports in an extended fabric. See the Fabric OS Command Reference for additional information on the values to use with this parameter. Trunking distances Enhanced trunking support for switches with single ASIC platforms is summarized in Table 85. Fabric OS 6.2 administrator guide 443
