VLAN Configuration Files

Configurations for VLAN IDs 1 to 1005 are written to the vlan.dat file (VLAN database), and you can display

them by entering the show vlan privileged EXEC command. The vlan.dat file is stored in flash memory. If

the VTP mode is transparent, they are also saved in the switch running configuration file.

In a switch stack, the whole stack uses the same vlan.dat file and running configuration. On some switches,

the vlan.dat file is stored in flash memory on the active switch.

You use the interface configuration mode to define the port membership mode and to add and remove ports

from VLANs. The results of these commands are written to the running-configuration file, and you can display

the file by entering the show running-config privileged EXEC command.

When you save VLAN and VTP information (including extended-range VLAN configuration information)

in the startup configuration file and reboot the switch, the switch configuration is selected as follows:

• If the VTP mode is transparent in the startup configuration, and the VLAN database and the VTP domain

• If the VTP mode or domain name in the startup configuration does not match the VLAN database, the

• In VTP versions 1 and 2, if VTP mode is server, the domain name and VLAN configuration for VLAN

IDs 1 to 1005 use the VLAN database information. VTP version 3 also supports VLANs 1006 to 4094.

VLAN Membership Characteristics

A dynamic-access port can belong

to one VLAN (VLAN ID 1 to

4094) and is dynamically assigned

by a VLAN Member Policy Server

(VMPS).

You can have dynamic-access ports

and trunk ports on the same switch,

but you must connect the

dynamic-access port to an end

station or hub and not to another

switch.

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.

Configuring VLANs

VTP Characteristics

VTP is required.

Configure the VMPS and the client

with the same VTP domain name.

To participate in VTP, at least one

trunk port on the switch or a switch

stack must be connected to a trunk

port of a second switch or switch

stack.

VTP is not required; it has no effect

on a voice VLAN.
