IP phone access methods

Connecting the host and the IP phone in series

As shown in
When the host and the IP phone are connected in series, the host and the IP phone must be assigned to
different VLANs, and the IP phone must be able to send out VLAN-tagged packets, so that the data traffic
and the voice traffic can be distinguished. Also, you must configure the port to allow the voice VLAN and
the PVID.

Connecting the IP phone to the device separately

As shown in
applies when the IP phone sends out untagged voice packets. In this case, you must configure the voice
VLAN as the PVID of the port and configure the port to allow the PVID.

Voice VLAN assignment modes

A port can be assigned to a voice VLAN in automatic mode or manual mode.
Automatic mode
Automatic mode is suitable for scenarios where PCs and IP phones connected in series access the
network through the device and ports on the device transmit both voice traffic and data traffic, as shown
in Figure 51.
The system matches the source MAC address carried in the protocol packets sent when an IP phone is
powered on against the device's OUI addresses. If the system finds a match, it automatically assigns the
