Example for Configuring the Voice VLAN Capability of LLDP to Provide VoIP Service
Networking Requirements
Data flows of the HSI, VoIP, and IPTV services are transmitted over a network. Users require high-quality VoIP service. Therefore, voice data flows must be transmitted with a high priority. If voice devices connected to a switch support LLDP, you can configure the voice VLAN capability of LLDP on the switch to provide the VoIP service. The switch then uses LLDP to assign a VLAN ID to the voice devices.
As shown in Figure 1, after the voice VLAN capability of LLDP is configured on the Switch, the voice device can use LLDP to learn its VLAN ID.
Configuration Roadmap
The configuration roadmap is as follows:
- Create VLANs, and then configure the link type and default VLAN for the interface connected to the voice device. Use VLAN 10 as the default VLAN of GE0/0/1 to forward data flows of the HSI and IPTV services, and use VLAN 20 as the voice VLAN for LLDP to forward VoIP voice flows.
- Enable LLDP globally.
- Configure the voice VLAN capability of LLDP.
Procedure
- Configure VLANs and the interface connected to the voice device on the Switch.
# Create VLAN 10 and VLAN 20.
<HUAWEI> system-view [HUAWEI] sysname Switch [Switch] vlan batch 10 20
# Configure the link type and default VLAN of the interface connected to the voice device.

- Enable LLDP.
[Switch] lldp enable - Configure the voice VLAN capability of LLDP.

- Verify the configurations.
# Run the display lldp local command to check the configuration of the LLDP's voice VLAN capability.
