Voice VLAN
H3C Low-End Ethernet Switches Configuration Examples
Note:
The following describes the operations on VLAN traffic:
pvid: Indicates that the VLAN is configured as the default VLAN of the port.
untagged: Indicates that the port sends the traffic of the VLAN untagged.
tagged: Indicates that the port sends the traffic of the VLAN tagged.
For how to configure the default VLAN for a port and configure the port to send traffic
untagged/tagged, refer to the accompanied operation manual.
In the following configuration, Ethernet 1/0/10 is configured as a hybrid port.
II. Configuration on Switch B
Meeting room 1
Figure 2-3 Network diagram for Switch B
As two types of IP phones are connected to Switch B, the configuration on Ethernet
1/0/1 is different from that on Ethernet 1/0/2.
Ethernet 1/0/1
The IP phones connected to Ethernet 1/0/1 are configured with an IP address manually
and they send voice traffic untagged. As the port with the voice VLAN mode set to auto
does not support receiving untagged voice traffic, you should configure the voice VLAN
to operate in manual mode on the port. In addition, configure the voice VLAN as the
default VLAN of the port.
Ethernet 1/0/2
You can configure Ethernet 1/0/2 in a way similar to configuring Ethernet 1/0/10 on
Switch A. However, because only IP phones are connected to Ethernet 1/0/2, you can
assign the port to the voice VLAN manually to guarantee stable transmission for voice
traffic. For the Cisco IP phones connected to the port to communicate with the switch,
enable voice VLAN legacy on the port to notify them of the voice VLAN ID, so that the
Cisco IP phones can request IP addresses within the voice VLAN. Because the IP
