switchCfgTrunk

Enables or disables trunking on all the ports of a switch.

SYNOPSIS

switchcfgtrunk mode

DESCRIPTION

Use this command to enable or disable trunking on all the ports of a switch. Use portCfgTrunkPort to
enable or disable trunking on a single port.

When the command is executed to update the trunking configuration, the ports to which the configuration
applies are disabled and subsequently re-enabled with the new trunking configuration. Traffic through
these ports may be temporarily disrupted. The command issues a message that lists the VE/VEX_Ports
to which the configuration does not apply.

Although trunking configuration changes are applied at the switch level, they are tracked as a per-port
attribute and no switch-wide attribute is maintained to keep track of these changes. Whenever a new port
comes online as part of the switch, you must reapply the trunking configuration. For example, If you
remove a blade from a chassis while trunking is enabled for the ports on the blade, and you disable
trunking on the switch after you removed the blade, the blade ports will come online with trunking
enabled after you reinsert the blade. To avoid potentially disruptive behavior, reapply the trunking
configuration.

Trunking on Inter-Chassis Link (ICL) ports is always enabled and cannot be turned off by this command.

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