Configuring VLANs
Configuring a Voice VLAN
The commands in this example create a VLAN for voice traffic with a VLAN
ID of 25. Port 10 is set to an 802.1Q VLAN. In in this example, there are
multiple devices connected to port 10, so the port must be in general mode in
order to enable MAC-based 802.1X authentication. Next, Voice VLAN is
enabled on the port with the Voice VLAN ID set to 25. Finally, Voice VLAN
authentication is disabled on port 10 because the phone connected to that
port does not support 802.1X authentication. All other devices are required to
use 802.1X authentication for network access. For more information about
802.1X authentication, see "Configuring Port and System Security" on
page 469.
To configure the switch:
1 Create the voice VLAN.
console# configure
console(config)# vlan 25
console(config-vlan25)# exit
2 Enable the Voice VLAN feature on the switch.
console(config)#v oice vlan
3 Configure port 10 to be in general mode.
console(config)# interface te1/0/10
console(config-if-Te1/0/10)# switchport mode
general
4 Enable port-based 802.1X authentication on the port. This step is required
only if there are multiple devices that use port-based authentication
connected to the port.
console(config-if-Te1/0/10)# dot1x port-control
mac-based
5 Enable the voice VLAN feature on the interface
console(config-if-Te1/0/10)# voice vlan 25
NOTE:
In an environment where the IP phone uses LLDP-MED to obtain
configuration information, an additional step to enable LLDP-MED on the
interface would be required by issuing the lldp med command in Interface
Configuration mode.
