HCIP-4.3 DHCP静态绑定、租约

SW1：

dhcp enable
ip pool A  # vlan 8的地址池
 net 192.168.8.0 mask 24
 gateway-list 192.168.8.1
 dns-list 8.8.8.8 8.8.4.4
ip pool B  # vlan 9的地址池
 net 192.168.9.0 mask 24
 gateway-list 192.168.9.1
 dns-list 8.8.8.8 8.8.4.4
 #
int vlan 8
 dhcp select global
int vlan 9
 dhcp select global

一、静态绑定配置：

SW1：

ip pool A
 static-bind ip-address 192.168.8.8 mac-address 5489-987D-4DFB

查看命令：

dis ip pool name a used

ip pool A
 static-bind ip-address 192.168.8.9 mac-address 5489-987D-157A
Error：The static-MAC is exist in this IP-pool

5489-987D-157A已经在IP地址池中拿到了IP

解决办法：（1）交换机清空分配记录

<SW1>reset ip pool name a used

​ （2）用户自己清空

ipconfig/relaease  # 释放IP地址
ipconfig/renew  # 重新获取

二、租约

ip pool A
 lease day 2 hour 2  # 租期改成2天2个小时
