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.

Do not check the source MAC address of the packet and all

the packets can be transmitted in the voice VLAN.

The processing mode for the device to deal with the packet

is determined by whether the port permits

Note:

Don’t transmit voice stream together with other business packets in the voice VLAN except for

some special requirements.

The Voice VLAN function can be implemented on
