Enabling and disabling ISL Trunking You can enable or disable ISL Trunking for a single port or for an entire switch.When you execute the commands portCfgTrunkPort or switchCfgTrunk to update the trunking configuration, the ports for which the configuration applies are disabled and re-enabled with the new trunk configuration. As a result, traffic through those ports could be disrupted. IMPORTANT: Trunking is performed based on QoS configuration on the master and the slave ports. That is, in a given trunk group, if there are some ports with QoS enabled and some with QoS disabled, they would form two different trunks, one with QoS enabled and the other with QoS disabled. To enable or disable ISL Trunking on one port: 1. Connect to the switch and log in as admin. 2. Enter the portCfgTrunkPort command. The format is: portcfgtrunkport [slotnumber/]portnumber mode slotnumber portnumber mode Specifies the number of the slot in which the port blade containing the port is located. This operand only required for Directors. Specifies the number of the port on which you want to enable or disable trunking. Enables (1) or disables (0) trunking on the specified port. The following example enables trunking on slot 1, port 3: switch:admin> portcfgtrunkport 1/3 1 done. switch:admin> To enable or disable ISL Trunking for all of the ports on a switch: 1. Connect to the switch and log in as admin. 2. Enter the switchCfgTrunk command. The format is: switchcfgtrunk mode Mode 1 enables and mode 0 disables ISL Trunking for all ports on the switch. The following example enables trunking all ports in the switch. switch:admin> switchcfgtrunk 1 Committing configuration...done. switch:admin> Fabric OS 6.1.x administrator guide 361
