dhcp怎么开启(dhcp在哪里设置启用)

一、若需将交换机之前配置清空，命令

reset saved-configuration 保存的配置文件将被删除

The saved configuration file will be erased. Are you sure? [Y/N]:y

保存的配置文件将被删除。你确定吗？[Y/N]：Y

reboot 重新启动

Current configuration may be lost after the reboot, save current configuration？[Y/N]:n

重新启动后，当前配置可能会丢失，请保存当前配置，选N

This command will reboot the device. Continue? [Y/N]:y

此命令将重新启动设备。持续 选Y

二、创建用户名和密码

local-user cd

password simple A123456789

authorization-attribute user-role level-15 授权属性用户角色级别15

service-type telnet 服务类型telnet

service-type http https

dhcp enable 启用 dhcp

ip http enable 启用 ip http

ip https enable

telnet server enable

undo info-center enable 关闭信息中心提示

三，创建vlan

vlan 2 3

interface range G1/0/2 to G1/0/8 接口范围：2至8口

port link-type access

port access vlan 2

int vlan2

ip address 192.168.2.1 24

dhcp server ip-pool 2

network 192.168.2.0 24

dns-list 114.114.114.114 8.8.8.8

gateway-list 192.168.2.1

forbidden-list 192.168.2.1

forbidden-list 192.168.2.254

配置vlan3

interface range G1/0/9 to G1/0/16

port link-type access

port access vlan 3

int vlan3

ip address 192.168.3.1 24

dhcp server ip-pool 3

network 192.168.3.0 24

dns-list 114.114.114.114 8.8.8.8

gateway-list 192.168.3.1

forbidden-list 192.168.3.1

forbidden-list 192.168.3.254

四，配置trunk端口，允许vlan互通

int g1/0/1

port link-type trunk

port trunk permit vlan all

display ip interface brief 显示ip接口简介
