VLAN Restrictions
■ A port must be a member of at least one VLAN. In the factory default
configuration, all ports are assigned to the default VLAN
(DEFAULT_VLAN; VID = 1).
■ A port can be assigned to several VLANs, but only one of those assign-
ments can be untagged. (The “Untagged” designation enables VLAN oper-
ation with non 802.1Q-compliant devices.)
■ An external router must be used to communicate between tagged VLANs
on the switch.
■ Before you can delete a VLAN, you must first re-assign all ports in the
VLAN to another VLAN.
