VLAN Membership Characteristics
Voice VLAN
A voice VLAN port is an access port attached to a Cisco
IP Phone, configured to use one VLAN for voice traffic
and another VLAN for data traffic from a device attached
to the phone.
For more information about voice VLAN ports, see
Chapter 13, "Configuring Voice VLAN."
Private VLAN
A private VLAN port is a host or promiscuous port that
belongs to a private VLAN primary or secondary VLAN.
For information about private VLANs, see
"Configuring Private VLANs."
Tunnel
Tunnel ports are used for IEEE 802.1Q tunneling to
(dot1q-tunnel)
maintain customer VLAN integrity across a
service-provider network. You configure a tunnel port on
an edge switch in the service-provider network and
connect it to an IEEE 802.1Q trunk port on a customer
interface, creating an asymetric link. A tunnel port belongs
to a single VLAN that is dedicated to tunneling.
For more information about tunnel ports, see
"Configuring IEEE 802.1Q and Layer 2 Protocol
Tunneling."
For more detailed definitions of access and trunk modes and their functions, see
page
When a port belongs to a VLAN, the switch learns and manages the addresses associated with the port
on a per-VLAN basis. For more information, see the
page
Configuring Normal-Range VLANs
Normal-range VLANs are VLANs with VLAN IDs 1 to 1005. If the switch is in VTP server or
VTP transparent mode, you can add, modify or remove configurations for VLANs 2 to 1001 in the
VLAN database. (VLAN IDs 1 and 1002 to 1005 are automatically created and cannot be removed.)
When the switch is in VTP transparent mode, you can also create extended-range VLANs (VLANs with
Note
IDs from 1006 to 4094), but these VLANs are not saved in the VLAN database. See the
Extended-Range VLANs" section on page
Configurations for VLAN IDs 1 to 1005 are written to the file vlan.dat (VLAN database), and you can
display them by entering the show vlan privileged EXEC command. The vlan.dat file is stored in flash
memory.

VTP Characteristics
VTP is not required; it has no affect on a
voice VLAN.
The switch must be in VTP transparent
mode when you configure private VLANs.
When private VLANs are configured on the
Chapter 14,
switch, do not change VTP mode from
transparent to client or server mode.
VTP is not required. You manually assign
the tunnel port to a VLAN by using the
switchport access vlan interface
configuration command.
