锐捷核心交换机配置DHCP

1、进入特权模式

conf terminal

2、开启交换机DHCP服务器功能

service dhcp

3、配置DHCP服务器信息示例：

ip dhcp pool office
 lease 3 0 0 
 network 10.115.0.0 255.255.248.0
 dns-server 10.115.67.2 114.114.114.114 
 default-router 10.115.7.254 
 
#说明：
#ip dhcp pool office   <===  定一个DHCP地址池，名称为office                   ip dhcp pool [name]
#  lease  3  0  0         <===  定义DHCP的有效期为3天，时间可设置。               lease  [day] [hours] [minutes]
#  network 10.115.0.0 255.255.248.0   <===定义DHCP地址池的网段,可选设置网址范围   network [network] [mask] [start ip] [end ip]
#  dns-server 10.115.67.2 114.114.114.114   <===定义DHCP分配的DNS服务器          dns-server [dns ip1]  [dns ip2]
#  default-router 10.115.7.254              <===定义DHCP分配默认网关             default-router [default-gateway ip]

4、可选配置：dhcp保留地址，设置此地址不会通过dhcp分发出去

ip dhcp excluded-address 10.84.128.134 10.84.128.135

#说明：DHCP保留地址 10.84.128.134~10.84.128.135         ip dhcp excluded-address [start ip] [end ip]

5、可选配置：DHCP设置为指定MAC地址分配固定的IP

ip dhcp pool sd-wan-cpe-cus
 hardware-address f08e.db17.7a07
 host 10.115.255.3 255.255.255.248
 dns-server 114.114.114.114 
 default-router 10.115.255.1 
 
#说明：锐捷交换机分配固定的IP，需要单独建立一个DHCP地址池
#  ip dhcp pool sd-wan-cpe-cus				 <===  定一个DHCP地址池，sd-wan-cpe-cus	             ip dhcp pool [name]
#	 hardware-address f08e.db17.7a07       	 <===  定义需要设置指定IP的设备的MAC地址					 hardware-address [mac]
#	 host 10.115.255.3 255.255.255.248    	 <===  定义需要设置的指定IP地址与掩码						 host [network] [mask]
#	 dns-server 114.114.114.114 			 <===定义DHCP分配的DNS服务器 							  dns-server [dns ip1]  [dns ip2]
# 	 default-router 10.115.255.1 			 <===定义DHCP分配默认网关								  default-router [default-gateway ip]

6、可选配置：arp与mac地址绑定，当ip-mac不符合绑定的ip不能接入网络

arp 10.113.65.254 f08e.db17.89a8 arpa

#说明： 将ip地址10.113.65.254于mac地址f08e.db17.89a8 绑定        arp [ip] [mac-address] arpa

7、可选配置： mac地址过滤，不允许某个mac地址在所设置的vlan接入

mac-address-table filtering d049.7c23.63cc vlan 510

#说明： 不允许mac为d049.7c23.63cc设备接入vlan510       mac-address-table filtering [mac-address] vlan [vlan number]
