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.
–
add adds the defined list of VLANs to those currently set instead of
replacing the list.
–
remove removes the defined list of VLANs from those currently set
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.
