思科是全球高端顶尖的通讯厂商，他出产的路由器功能也是世界级的，那么你知道思科7960路由器如何配置Voice vlan吗?下面是小编整理的一些关于思科7960路由器如何配置Voice vlan的相关资料，供你参考。

思科7960路由器配置Voice vlan的方法：

cisco7960 P1连接3550 F0/5端口

用IEEE 802.1Qframes标准端口承载语音流量

switch

conf t

mls qos

vlan 2

name access

exit

vlan 3

name voice

exit

interface f0/5

mls qos trust cos

switchport mode access

switchport access vlan 3

switchport voice vlan 2

end
