– all specifies all VLANs from 1 to 4093. This keyword is not allowed on
commands that do not permit all VLANs in the list to be set at the
same time.
–

replacing the list.
–

instead of replacing the list. Valid IDs are from 1 to 4093; extended-
range VLAN IDs of the form X-Y or X,Y,Z are valid in this command.
–
except lists the VLANs that should be calculated by inverting the
defined list of VLANs. (VLANs are added except the ones specified.)

User Guidelines
Untagged traffic received on a trunk port is forwarded on the native VLAN, if
configured.
To drop untagged traffic on a trunk port, remove the native VLAN from the
trunk port. (Ex. switchport trunk allowed vlan remove 1.) Management
traffic is still allowed on the trunk port in this configuration.
The no form of the command sets the trunk port back to the defaults.
