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.

Enable
UNTAG packet
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.

VLAN TAG
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.
Disable
UNTAG packet
Do not check the source MAC address of the packet and all
the packets can be transmitted in the voice VLAN.

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
Global Config, Port Config
and
OUI Config
pages.
10.3.1 Rate Limit
Rate limit functions to control the ingress/egress traffic rate on each port via configuring the
available bandwidth of each port. In this way, the network bandwidth can be reasonably distributed
and utilized.
