After being enabled with the MUX VLAN function, the port can no longer be configured with
VLAN mapping or VLAN stacking.
NOTE
l Disabling MAC address learning or limiting the number of learned MAC addresses on an interface
affects the MUX VLAN function on the interface.
l The MUX VLAN and port security functions cannot be enabled on the same interface.
l The MUX VLAN and MAC address authentication cannot be enabled on the same interface.
l The MUX VLAN and 802.1x authentication cannot be enabled on the same interface.

3.7.6 Checking the Configuration
After a MUX VLAN is configured, you can check the principal VLAN ID, subordinate VLAN
ID, and VLAN type.
Prerequisite
The configurations of a MUX VLAN are complete.
Procedure
Step 1 Run the display mux-vlan command to check information about the MUX VLAN.

3.8 Configuring a Voice VLAN to Transmit Voice Data
A voice VLAN is used to transmit voice data.
3.8.1 Establishing the Configuration Task
Before configuring a voice VLAN, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the data required for the configuration. This
will help you complete the configuration task quickly and accurately.
Applicable Environment
Voice and non-voice data are transmitted on networks. Voice data is configured with a higher
priority than non-voice data to reduce the probability of the transmission delay and packet loss.
In most cases, an Access Control List (ACL) is configured to distinguish voice data from non-
voice data, and the Quality of Service (QoS) is used to ensure the transmission quality of voice
data.
Voice over IP (VoIP) phones are commonly used. If an ACL is configured to distinguish voice
data from non-voice data, and QoS is used to ensure the transmission quality of voice data, each
terminal needs to be configured with an ACL rule. This increases the network administrator's
workload and burdens maintenance.
The voice VLAN technique is introduced to solve the preceding problem.
After being enabled with the voice VLAN function, a device determines voice data based on
source MAC addresses of received frames, adds ports that receive voice data to a voice VLAN,
