Voice VLAN
H3C Low-End Ethernet Switches Configuration Examples
phones send tagged voice traffic, you should configure the port to send the traffic of the
voice VLAN tagged.
GigabitEthernet 1/1/2
The port sends the voice traffic received on Switch B. As the meeting rooms should use
a voice VLAN different from that for the office area, configure VLAN 400 as the voice
VLAN on Switch B and configure the port to send the traffic of VLAN 400 tagged.

In the following configuration, Ethernet 1/0/1 is configured as an access port, and
Ethernet 1/0/2 and GigabitEthernet 1/1/2 are configure as trunk ports.
III. Configuration on Core Switch
Figure 2-4 Network diagram for the Core Switch
The core switch forwards traffic, allocates IP addresses to IP phones, and specifies the
voice VLAN and the voice server address.
According to the configuration on Switch A and Switch B, the core switch is required to
forward the traffic of VLAN 100, VLAN 200, and VLAN 400, and allocate IP addresses
to IP phones in VLAN 200 and VLAN 400.
As analyzed earlier, when an IP phone is powered up, it first gets an IP address in the
default VLAN (VLAN 100) from the DHCP server. The DHCP server should return not
lists the port configurations on Switch B.
