Table 9-2 Port voice VLAN mode and voice stream processing mode
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.

Link type of the port and processing mode
Processing Mode
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
the VLAN or not, independent of voice VLAN
security mode.
