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.
