Port Voice VLAN Mode

A voice VLAN can operate in two modes: automatic mode and manual mode.

Automatic Mode: In this mode, the switch automatically adds a port which receives voice packets

to voice VLAN and determines the priority of the packets through learning the source MAC of the

UNTAG packets sent from IP phone when it is powered on. The aging time of voice VLAN can be

configured on the switch. If the switch does not receive any voice packet on the ingress port within

the aging time, the switch will remove this port from voice VLAN. Voice ports are automatically

added into or removed from voice VLAN.

Manual Mode: You need to manually add the port of IP phone to voice VLAN, and then the switch

will assign ACL rules and configure the priority of the packets through learning the source MAC

address of packets and matching OUI address.

In practice, the port voice VLAN mode is configured according to the type of packets sent out from

voice device and the link type of the port. The following table shows the detailed information.



Security Mode of Voice VLAN

When voice VLAN is enabled for a port, you can configure its security mode to filter data stream. If

security mode is enabled, the port just forwards voice packets, and discards other packets whose

source MAC addresses do not match OUI addresses. If security mode is not enabled, the port

forwards all the packets.

When the source MAC address of the packet is the OUI

address that can be identified, the packet can be

transmitted in the voice VLAN. Otherwise, the packet will

be discarded.

The processing mode for the device to deal with the packet

is determined by whether the port permits the VLAN or not,

independent of voice VLAN security mode.
