Cisco设备上设置DHCP实例
一位客户想把DHCP SERVER迁移到6509交换机的MSFC上,要求还挺复杂: 1.同时为多个VLAN的客户机分配地址 2.VLAN内有部分地址采用手工分配的方式 3.为客户指定网关、Wins服务器等 4.VLAN 2的地址租用有效期限为1天,其它为3天 5.按MAC地址为特定用户分配指定的IP地址 最终配置如下： ip dhcp excluded-address 10.1.1.1 10.1.1.19 //不用于动态地址分配的地址 ip dhcp excluded-address 10.1.1.240 10.1.1.254 ip dhcp excluded-address 10.1.2.1 10.1.2.19 ! ip dhcp pool global //global是pool name， 由用户指定 network 10.1.0.0 255.255.0.0 //动态分配的地址段 domain-name client.com //为客户机配置域后缀 dns-server 10.1.1.1 10.1.1.2 //为客户机配置dns服务器 netbios-name-server 10.1.1.5 10.1.1.6 //为客户机配置wins服务器 netbios-node-type h-node //为客户机配置节点模式（影响名称解释的顺利,如h-node=先通过wins服务器解释...） lease 3 //地址租用期限: 3天 ip dhcp pool vlan1 network 10.1.1.0 255.255.255.0 //本pool是global的子pool, 将从global pool继承domain-name等option default-router 10.1.1.100 10.1.1.101 //为客户机配置默认网关 ! ip dhcp pool vlan2 //为另一VLAN配置的pool network 10.1.2.0 255.255.255.0 default-router 10.1.2.100 10.1.2.101 lease 1 ! ip dhcp pool vlan1_john //总是为MAC地址为...的机器分配...地址 host 10.1.1.21 255.255.255.0 client-identifier 010050.bade.6384 //client-identifier=01加上客户机网卡地址 ! ip dhcp pool vlan1_tom host 10.1.1.50 255.255.255.0 client-identifier 010010.3ab1.eac8 相关的DHCP调试命令： no service dhcp //停止DHCP服务[默认为启用DHCP服务] sh ip dhcp binding //显示地址分配情况 show ip dhcp conflict //显示地址冲突情况 debug ip dhcp server {events | packets | linkage} //观察DHCP服务器工作情况 如果DHCP客户机分配不到IP地址，常见的原因有两个。第一种情况是没有把连接客户机的端口设置为Portfast方式。MS客户机开机后检查网卡连接正常，Link是UP的，就开始发送DHCPDISCOVER请求，而此时交换机端口正在经历生成树计算，一般需要30-50秒才能进入转发状态。MS客户机没有收到DHCP SERVER的响应就会给网卡设置一个169.169.X.X的IP地址。解决的方法是把交换机端口设置为Portfast方式：CatOS(4000/5000/6000): set spantree portfast mod_num/port_num enable; IOS(2900/3500): interface ... ; spanning-tree portfast。 另外一种情况是DHCP服务器和DHCP工作站不在同一个VLAN，这时候通常通过设置ip helper-address来解决： interface vlan1 ip address 10.1.1.254 255.255.255.0 //假设DHCP服务器地址为10.1.1.8 interface Vlan2 ip address 10.1.2.254 255.255.255.0 ip helper-address 10.1.1.8 //假设这是DHCP客户机所在的VLAN 4 static NAT

这个配置没什么复杂的，很简单，拓扑也就是2个3750堆叠后与一台路由器互联，都很容易。 值得学习的是，很多细节配置的很全面，很多安全性的feature都利用上了，而且也是很规范的配置。 是一个很有钱的企业请cisco写的，呵呵。杀鸡用牛刀了，呵呵。 Building configuration...
