2 配置类命令
鉴于独立的配置命令难以理解，下面都以具体的配置任务为例，列出完成此任务需要的所有命令，可能会有重复。
2.1 端口配置
system-view interface interface-type interface-number
2.1.1 配置为access并设置VLAN
port link-type access port access vlan vlan-id
2.1.2 配置为trunk并允许所有VLAN通过
port link-type trunk port trunk permit vlan all
2.2 开启端口环路检测
注意loopback-detection multi-port-mode，及loopback-detection action这两个命令在较新的交换机上才支持。
system-view loopback-detection enable loopback-detection multi-port-mode enable
2.2.1 开启access口环路检测
interface interface-type interface-number
loopback-detection enable
loopback-detection action { no-learning | semi-block | shutdown }
2.2.2 开启hybrid/trunk口环路检测
interface interface-type interface-number
loopback-detection enable
loopback-detection control enable
loopback-detection per-vlan enable
loopback-detection action { no-learning | semi-block | shutdown }
2.3 配置telnet登录
注意user privilege level是可选命令
system-view
user-interface vty first-number [ last-number ]
authentication-mode password
set authentication password { cipher | simple } password
user privilege level level
2.4 配置DHCP服务器
注意gateway-list和dns-list后最多可跟8个IP地址。
system-view
dhcp server ip-pool pool-name
network ip-address [ mask mask ]
gateway-list ip-address
dns-list ip-address
quit
dhcp server forbidden-ip low-ip-address [ high-ip-address ]
dhcp select global { interface interface-type interface-number [ to interface-type interface-number ] | all }
2.5 配置DHCP Snooping
system-view interface interface-type interface-number dhcp-snooping trust quit dhcp-snooping
