Configuring Voice VLANs

The Voice VLAN aging time is the time after which a port is removed from 

the Voice VLAN when VoIP traffic is no longer received on the port.
The Remaining Age starts to count down when the OUI’s MAC address 

expires from the MAC address table. Therefore, the MAC address aging 

time should be added to the overall aging time. For example, if you 

configure the MAC address table aging time to 30 seconds, and the voice 

VLAN aging time to 5 minutes, then after 5.5 minutes, a port will be 

removed from voice VLAN when VoIP traffic is no longer received on the 

port. Alternatively, if you clear the MAC address table manually, then the 

switch will also start counting down the Remaining Age.

The following example configures the Voice VLAN aging time as 3000 

minutes.

Console(config)#voice vlan aging 3000

Console(config)#

voice vlan

mac-address

This command specifies MAC address ranges to add to the OUI Telephony 

list. Use the 

no

 form to remove an entry from the list.

 - Defines a MAC address OUI that identifies VoIP 

devices in the network. (For example, 01-23-45-00-00-00)

mask-address

 - Identifies a range of MAC addresses. (Range: 80-

00-00-00-00-00 to FF-FF-FF-FF-FF-FF)

◆

VoIP devices attached to the switch can be identified by the 

manufacturer’s Organizational Unique Identifier (OUI) in the source 

MAC address of received packets. OUI numbers are assigned to 

manufacturers and form the first three octets of device MAC addresses. 

The MAC OUI numbers for VoIP equipment can be configured on the 

switch so that traffic from these devices is recognized as VoIP.
