1 验证类命令
1.1 查看配置文件
display current-configuration [ { begin | include | exclude } regular-expression ] display saved-configuration display startup
1.2 用户级别切换
super
1.3 显示接口状态及所属VLAN
display brief interface display interface interface-type interface-number
1.4 显示MAC地址列表
display mac-address [ dynamic | static ] [ interface-type interface-number ] [ vlan vlan-id ]
1.5 显示ARP列表
display arp [ static | dynamic | ip-address ] display arp [ static | dynamic ] | { begin | include | exclude } text
1.6 显示环路检测状态
display loopback-detection
1.7 显示DHCP Snooping状态
display dhcp-snooping display dhcp-snooping trust
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
