Command History

Usage Guidelines

If the trunking protocol is disabled on a switch, no port on that switch can apply new trunk

configurations. Existing trunk configurations are not affected—the TE port continues to function in

trunking mode, but only supports traffic in VSANs that it negotiated previously (when the trunking

protocol was enabled). Also, other switches that are directly connected to this switch are similarly

affected on the connected interfaces. In some cases, you may need to merge traffic from different port

VSANs across a non-trunking ISL. If so, you need to disable the trunking protocol.

The following example shows how to disable the trunk protocol feature.

switch# config terminal

switch(config)# no trunk protocol enable
