Fabric OS Command Reference 697

53-1001764-01

portCfgTrunkPort

Enables or disables trunking on a port.

SYNOPSIS portcfgtrunkport [slot/]port[,] mode

DESCRIPTION Use this command to enable or disable trunking on a port. Use switchCfgTrunk to enable or disable

trunking on all ports of a switch.

When the command is executed to update the trunking configuration, the port to which the configuration

applies is disabled and subsequently re-enabled with the new trunking configuration. Traffic through the

ports may be temporarily disrupted.

Disabling trunking fails if a Trunk Area (TA) is enabled on the port. Use the portTrunkArea command to

remove the TA before disabling trunking.

NOTES Enabling trunking requires an ISL Trunking license. You may disable trunking without a license.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in

place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

details.

The Fabric OS port configuration commands are not supported on FCoE ports.

Virtual FC Ports do not support frame-based trunking . If trunking is enabled for one of these ports in a

slot, and a Brocade FX8-24 Extension blade is inserted into the slot, the configuration is not honored and

the system logs a RASLOG error. An attempt to enable trunking for a Virtual FC port in a slot that

contains a Brocade FX8-24 is rejected.

OPERANDS This command has the following operands:

slot

For bladed systems only, specifies the slot number of the port to be configured,

followed by a slash (/).

port

Specifies the port to be configured, relative to its slot for bladed systems. Use

switchShow to display a listing of valid ports.

mode

Specify 1 to enable trunking on the specified port. Specify 0 to disable trunking on

the port. This operand is required. Trunking is enabled by default, when a trunking

license is present on the switch.

EXAMPLES To enable a port for trunking:

switch:admin> portcfgtrunkport 1/3, 1
