前面文章我们我们介绍了华三的dhcp三剑客DHCP三剑客-DHCP服务器全局配置DHCP中继DHCP Snooping配置和DHCP三剑客配置(2)温故而知新我们继续学习一下锐捷的配置方式一 DHCP服务器配置!service dhcp!ip dhcp pool vlan1190option 43 hex 8007.0000.013a.85fa.80 //可选配置当有AP自动获取地址与AC跨三层注册的时候才需要配置option43属性network 10.192.223.0 255.255.255.0dns-server 114.114.114.114 8.8.8.8default-router 10.192.223.1!注意AC地址由10进制转换为16进制比如AC地址为58.133.250.128转换为16进制为3A85FA80这样AP可以通过三层路由找到AC地址进行注册并上线前面固定格式80070000最后01代表1个AC地址。二 DHCP中继配置!service dhcp!vlan 10!interface vlan 10ip address 10.192.91.1 24ip helper-address 10.192.92.1 //在网关下指向dhcp服务器地址三 DHCP Snooping配置!ip dhcp snooping!interface range g1/0/1 to g1/0/47port link-access accessport default vlan 10dhcp snooping enable!interface gi0/48 //上行接口配置trust接口ip dhcp snooping trust!四 dhcp状态查看查看dhcp服务状态show ip dhcp pool查看 Snooping 绑定表show ip dhcp binding、show ip dhcp snooping binding、show ip dhcp snooping
