Security Mode of Voice VLAN
When voice VLAN is enabled for a port, it 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.

Table 4-7-2: Port Voice VLAN Mode and Voice Stream 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.
Processing 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.
