Voice VLAN Configuration 105
Configuring a voice VLAN to operate in manual mode
Refer to Table96 to configure a VLAN in manual mode.
You can enable voice VLAN feature for only one VLAN at a moment.
A port operating in the automatic mode cannot be added to/removed from a voice
VLAN.
When a voice VLAN operates in the security mode, the devices in it only permit
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 a voice VLAN. If you have to do so, make sure the
voice VLAN do not operate in the security mode.
