一、系统基础

system-view                    //    进入系统视图
sysname SW1-Group4             //    修改设备名称

save                           //    保存配置
reboot                         //    重启设备

undo shutdown                  //    开启接口

display current-configuration  //    查看当前配置(dis cu)
display saved-configuration    //    查看已保存配置

二、VLAN 与接口配置

vlan 40
 name Group4-PC-VLAN           // VLAN    命名(可选)

interface GigabitEthernet 1/0/1
 port link-type access
 port access vlan 40

interface GigabitEthernet 1/0/24
 port link-type trunk
 port trunk permit vlan 40
 port trunk pvid vlan 1

display vlan
display vlan brief
display port vlan
display mac-address

三、三层接口与网关

interface Vlan-interface 40
 ip address 10.0.4.254 255.255.255.0

interface GigabitEthernet 1/0/24
 undo portswitch               //    切换为三层接口
 ip address 10.99.0.2 255.255.255.252

display ip interface brief
display interface brief
display arp all

四、静态路由

ip route-static 0.0.0.0 0.0.0.0 10.99.0.1
ip route-static 10.0.1.0 255.255.255.0 10.99.0.1
ip route-static 10.0.2.0 24 10.99.0.1

display ip routing-table

ping 10.99.0.1
tracert 10.0.1.254

五、单臂路由

interface GigabitEthernet 1/0/1.10
 vlan-type dot1q vid 10
 ip address 192.168.10.254 255.255.255.0

六、SSH 远程管理

public-key local create rsa    //    首次配置需生成 RSA 密钥
ssh server enable

local-user admin class manage
 password simple Xgxy@2026
 service-type ssh
 authorization-attribute user-role level-15

user-interface vty 0 4
 authentication-mode scheme
 protocol inbound ssh
 idle-timeout 10 0

display ssh server status
display users

七、ACL 基础

acl basic 2000
 rule permit source 10.0.4.0 0.0.0.255

acl advanced 3000
 rule deny tcp source any destination any destination-port eq 80

interface GigabitEthernet 1/0/1
 packet-filter 3000 inbound

display acl all

八、常用查看命令速记

dis cu | inc vlan      //         查看 VLAN 相关配置

dis int br             //         接口状态
dis ip int br          // IP      地址表

dis ip rou             //         路由表
dis mac-add            // MAC     地址表
dis arp                // ARP
dis vlan               // VLAN    信息

ping -a 10.0.4.254 10.0.1.1
