Voice VLAN Configuration
1-7
Caution:
z You can enable the voice VLAN feature for only one VLAN at a moment.
z A port that has the link aggregation control protocol (LACP) enabled cannot have
the voice VLAN feature enabled at the same time.
z A port that has the QinQ or RRPP enabled cannot have the voice VLAN feature
enabled at the same time.
z Voice VLAN function can be effective only for the static VLAN. Once a dynamic
VLAN is enabled with voice VLAN function, it automatically becomes a static VLAN.
z When the voice VLAN mode on a port is the security mode, the device only permits
packets whose source addresses are the voice OUI addresses that can be identified.
Packets whose source addresses cannot be identified, including certain
authentication packets (such as 802.1x authentication packets), will be dropped. So,
do not transmit both voice data and service data in the voice VLAN. If you have to do
so, make sure the voice VLAN security mode is disabled.
