最近新建机房，需要通过核心交换机来DHCP，使得笔记本能通过此机房的出口连入internet。简单配置如下：
ip dhcp excluded-address 192.168.111.1 192.168.111.220
ip dhcp excluded-address 192.168.111.240 192.168.111.254
!
ip dhcp pool DHCP-POOL
network 192.168.111.0 255.255.255.0
default-router 192.168.111.254
dns-server 60.12.166.166
!
ip dhcp excluded-address 192.168.111.240 192.168.111.254
!
ip dhcp pool DHCP-POOL
network 192.168.111.0 255.255.255.0
default-router 192.168.111.254
dns-server 60.12.166.166
!
int vlan 111
ip add 192.168.111.254 255.255.255.0
no shut
no ip unr
no ip prox
no ip red
ip add 192.168.111.254 255.255.255.0
no shut
no ip unr
no ip prox
no ip red
然后笔记本接入到vlan111的端口就可以获得ip等相关信息了。
