配置LLDP可配置VOICE VLAN功能实现IP语音接入交换机示例
组网需求
网络中有HSI、VoIP和IPTV等数据流，用户对语音通话质量较敏感，需要提高语音数据流的传输优先级，以保证用户的通话质量。如果语音设备支持LLDP协议，可以在交换机上启用LLDP可配置VOICE VLAN功能实现IP语音接入，交换机通过LLDP协议给语音设备分配VLAN ID。
如图3-15所示，Switch配置LLDP可配置VOICE VLAN功能后，语音设备通过LLDP功能学习到VLAN。
配置思路
采用如下的思路配置LLDP可配置VOICE VLAN功能实现IP语音接入交换机：
- 创建VLAN并配置接口类型及缺省VLAN。VLAN10作为接口GE1/0/1的缺省VLAN对HSI和IPTV的数据流进行转发。VLAN20用于LLDP可配置的VOICE VLAN对VoIP的语音流进行转发。
- 全局LLDP使能。
- 配置LLDP可配置VOICE VLAN功能。
操作步骤
- 配置Switch的VLAN和接口
# 创建VLAN10、VLAN20。
<Quidway> system-view [Quidway] sysname Switch [Switch] vlan batch 10 20
# 配置接口类型和缺省VLAN。
[Switch] interface gigabitethernet 1/0/1 [Switch-GigabitEthernet1/0/1] port hybrid pvid vlan 10 [Switch-GigabitEthernet1/0/1] port hybrid untagged vlan 10 [Switch-GigabitEthernet1/0/1] quit
- 配置LLDP使能
[Switch] lldp enable - 配置LLDP可配置VOICE VLAN功能
[Switch] interface gigabitethernet 1/0/1 [Switch-GigabitEthernet1/0/1] port hybrid tagged vlan 20 [Switch-GigabitEthernet1/0/1] lldp tlv-enable med-tlv network-policy voice-vlan vlan 20 [Switch-GigabitEthernet1/0/1] quit [Switch] quit
- 检查配置结果
# 执行命令display lldp local，查看LLDP可配置VOICE VLAN功能是否配置正确。
