Voice VLAN
H3C Low-End Ethernet Switches Configuration Examples
Note:
The above procedure describes how a common IP phone gets an IP address. The
procedure may differ depending on your IP phone. For the actual procedure of your IP
phone, refer to its user manual.
In this network, as Ethernet 1/0/10 of Switch A is required to forward traffic of the default
VLAN and the voice VLAN, you should configure Ethernet 1/0/10 as a trunk port or
hybrid port. In this example, Ethernet 1/0/10 is configured as a hybrid port. As the traffic
from the PCs is untagged, it will be transmitted through the default VLAN. Configure
VLAN 100 as the default VLAN and configure the port to transmit the traffic of the
default VLAN untagged. As the IP phones send tagged traffic after getting IP addresses
within the voice VLAN, configure VLAN 200 as the voice VLAN and configure the voice
VLAN to operate in automatic mode on the port. Thus, the port can join/exit the voice
VLAN automatically.
Note:
A hybrid port with voice VLAN enabled in automatic mode joins the voice VLAN in
tagged mode automatically and sends the traffic of the voice VLAN tagged.
On Switch A, GigabitEthernet 1/1/1 is uplinked to the core switch to transmit both
service traffic and voice traffic. To discriminate data, configure the port as a trunk port to
carry VLAN 100 and VLAN 200. As the switch is required to send traffic of the two
VLANs tagged, do not configure either of them as the default VLAN.
