The following example sets the speed for all ports on the switch to 2 Gbit/second: switch:admin> switchcfgspeed 2 Committing configuration...done. switch:admin> The following example sets the speed for all ports on the switch to auto-negotiate: switch:admin> switchcfgspeed 0 Committing configuration...done. switch:admin> Displaying trunking information The trunkShow command offers an efficient means of listing all the trunks and members of a trunk. You can easily discover the peer ports for disabling a port, disconnecting a port, or adding additional members. 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: • Number identifier. • Port-to-port connections, listed in the following format: local_port_number -> remote_port_number. • WWNs of the remote switches. • Deskew values (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 sets the minimum deskew value of the shortest ISL to 15. • Master ports. 1. Connect to the switch and log in as admin. 2. Issue the trunkShow command. The following 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 switch:admin> deskew 16 Master deskew 15 deskew 16 Master deskew 15 deskew 17 deskew 16 deskew 16 Master deskew 15 Trunking over extended fabrics In addition to the criteria listed in "Standard trunking criteria" on page 168, observe the following criteria for trunking over extended fabrics: • ISL trunking over extended fabrics is supported on switches running Fabric OS 3.2.0 (or later) or 4.4.0 (or later). • Extended Fabrics and ISL Trunking licenses are required on all participating switches. • The vc_translation_link_init parameter must be set the same on all ports in an extended trunk. (For details on this parameter, see "For dynamic long-distance links, you can approximate the number of buffer credits using the following formula:" on page 165.) Fabric OS 5.x administrator guide 173
