It is possible to configure the general mode acceptable frame types of a port
while the port is in access or trunk mode. Doing so does not change the
configuration of the port until it is configured to be in general mode.
Example
The following example configures 1/0/8 to discard untagged frames at ingress.
console(config)#interface gigabitethernet 1/0/8
console(config-if-Gi1/0/8)#switchport general acceptable-frame-type tagged-
only
switchport general allowed vlan
Use the switchport general allowed vlan command in Interface
Configuration mode to add VLANs to or remove VLANs from a general port.
