快速配置CISCO语音VLAN
1.在三层上新建VLAN[*]en
[*]vlan database #进vlan配置
[*]vlan 125 name awaya125#创建vlan
[*]exit
[*]conf t
[*]int vlan125 #进单个vlan配置
[*]ip add 192.168.125.1 255.255.255.0 #配置VLAN网关
[*]no shut
[*]show ip int b #查看端口状态 ?
[*]wr
2.在二层交换机配置voicevlan
[*]en
[*]conf t
[*]lldp run #起lldp服务
[*]int ra f0/1-48 #进对应端口
[*]sw mode acc voice vlan 125 #划入语音VLAN
[*]no shut
[*]wr
-----------------------------------------
3.在二层交换机上配置端口绑定
[*]#conf t
[*]<config>#int range f0/1-24
[*]<config>#switchport port-security mac-address sticky
[*]<config>#switchport port-security max 2
[*]<config>#switchport port-security violation protect
[*]<config>#switchport port-security
[*]<config>#end#wr如果需要清空端口学习到的MAC信息，需要进入这个端口，no掉port-security的信息，然后再重新开启：
[*]<config>#int range f0/1-24
[*]<config>#no switchport port-security mac-address sticky
[*]<config>#no switchport port-security max 2
[*]<config>#no switchport port-security violation protect
[*]<config>#no switchport port-security
[*]<config>#switchport port-security mac-address sticky
[*]<config>#switchport port-security max 2
[*]<config>#switchport port-security violation protect
[*]<config>#switchport port-security
[*]<config>#shutdown
[*]<config>#no shutdown
[*]<config>#end#wr
