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.
Security Mode Packet Type Processing Mode
UNTAG packet
Packet with voice
VLAN TAG
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.
Enable
Packet with other
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.
UNTAG packet
Packet with voice
VLAN TAG
Do not check the source MAC address of the packet and all
the packets can be transmitted in the voice VLAN.
Disable
Packet with other
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.
