Usage Guidelines
The vlan-list format is all | none | [add | remove | except] vlan-atom [ ,vlan-atom... ]:
•
all specifies all VLANs from 1 to 4094. This is the default. This keyword is not allowed on commands
that do not permit all VLANs in the list to be set at the same time.
•
none specifies an empty list. This keyword is not allowed on commands that require certain VLANs to
be set or at least one VLAN to be set.
•
add adds the defined list of VLANs to those currently set instead of replacing the list. Valid IDs are
from 1 to 1005; extended-range VLANs (VLAN IDs greater than 1005) are valid in some cases.
