IP phone access methods
Connecting the host and the IP phone in series
As shown in
, the host is connected to the IP phone, and the IP phone is connected to the
device. In this scenario, the following requirements must be met:
•
The host and the IP phone use different VLANs.
•
The IP phone is able to send out VLAN-tagged packets, so that the device can differentiate
traffic from the host and the IP phone.
•
The port connecting to the IP phone forwards packets from the voice VLAN and the PVID.
Figure 49 Connecting the host and IP phone in series
Connecting the IP phone to the device
As shown in
, the IP phone is connected to the device without the presence of the host. Use
this connection method when the IP phone sends out untagged voice packets. In this scenario, you
must configure the voice VLAN as the PVID of the port, and configure the port to forward the packets
from the PVID.
