juniper 设备和其他厂商有所不同，采用提交生效的配置理念。大大减少了误操作。注：所有配置配置完毕后不会立即生效，需要commit提交生效。
1 开机指导
开机后：
login: root
Last login: Fri Jan 17 22:21:55 on ttyd0
--- JUNOS 7.2R3.3 built 2002-03-23 02:44:36 UTC
Terminal type? [vt100] <enter>
root@%
注意使用root用户登录的情况下，输入帐号/密码以后，默认是进入shell模式的（而只有root用户帐号有这个现象），要输入cli命令进入用户模式：
root@% cli
root>
2 配置模式
用户模式下输入configure命令进入配置模式，配置模式下可以对设备进行各种参数的配置
root> configure
2.1 设置root用户密码
命令：
set system root-authentication plain-text-password
初始化root用户是没有密码的，在第一次进行配置的时候必须要配置root密码才能commit成功。密码采用字母+数字方式。
Example:
set system root-authenticationplain-text-password
New password:
Retype new password:
2.2 添加系统用户
命令：
set system login user juniper uid 2000 <-设置用户名为juniper用户id为2000
set system login user juniper> set system login user juniper authenticationplain-text-password <-设置juniper用户的密码
2.3 设置主机名
命令：
set system host-name M7i_GZ <-设置主机名为M7i_GZ
2.4 开启系统telnet服务
命令：
set system services telnet
说明：系统默认是没有打开telnet功能的，只有打开telnet服务之后才能从网络上登陆到网络设备。
2.5 开启系统ftp服务
命令：
set system services ftp
说明：系统默认是没有打开ftp功能的，只有打开ftp服务之后才能从网络上ftp到网络设备。
2.6 配置SNMP
set snmp community <community> authorization < read-only/ read-write> clients <prefix> # 设置SNMP字符串
set snmp trap-options source-address192.168.1.1 #设置snmp trap的原地址为192.168.1.1
set snmp contact <contact> #设置snmp的联系信息
set snmp engine-id local <local> #设置snmp v3 engine> set snmp description <description> #设置snmp的系统描述
2.7 配置物理端口参数
2.7.1 配置端口描述
user@host#set interface ge-slot/pic/port description description
2.7.2 配置端口MTU
user@host#set interface ge-slot/pic/port mtu mtu-number
2.7.3 配置端口速率
user@host#set interface ge-slot/pic/port ether-options speed (10m |100m | 1g)
2.7.4 配置端口双工
user@host#set interface ge-0/0/0 ether-options link-mode (automatic| full-duplex |
half-duplex )
2.7.5 配置端口自动协商
user@host#set interface ge-0/0/0 ether-options (auto-negotiation |
no-auto-negotiation )
注：如需强制双工或强制速率需要配置user@host#set interface ge-0/0/0ether-options no-auto-negotiation
root@host# set interfaces ge-3/0/0 ether-optionsauto-negotiation
2.7.6 关闭端口
root@host# set interfaces ge-0/0/0 disable
2.7.7 配置物理端口二层接口
root@host# set interfaces ge-0/0/16 unit 0 familyethernet-switching port-mode access
2.7.8 配置物理端口三层接口
EX交换机物理接口可以支持三层路由接口功能，直接可以在接口上配置三层地址
root@host# set interfaces ge-0/0/17 unit 0 family inet address 192.168.20.1/24
2.8 配置VLAN
初始化配置时候，所有端口属于default VLAN，defaultvlan 的默认ID是0
2.8.1 创建二层VLAN
set vlans vlan100 vlan-id 100
2.8.2 创建三层vlan
set vlans vlan2061 descriptionGUANLI
set vlans vlan2061 vlan-id 2061
set vlans vlan2061 l3-interfacevlan.2061
set interfaces vlan unit 2061 familyinet address 172.16.61.52/24
2.8.3 接口划入VLAN
为端口配置VLAN 100 ACCESSS
root@host# set interfaces ge-0/0/1 unit 0 family ethernet-switchingvlan members 100
2.8.4 配置Vlan trunk
配置端口作trunk端口，支持802.1Q的标准封装。
user@host# set interfaces name unit 0 family ethernet-switchingport-mode trunk
#配置端口的VLAN模式为trunk模式
user@host# set interfaces name unit 0 family ethernet-switchingvlan members （all|number）
2.8.5 配置 native-vlan-id
EX在trunk端口下支持native-vlan(拆标签的VLAN) 的配置：
root@host# set interface ge-0/0/8 unit 0 family Ethernet-switchnative-vlan-id purple
2.14 静态路由协议
set routing-options static route 0.0.0.0/0 next-hop172.16.61.1
3 DHCP设置
set system services dhcp name-server 202.118.176.2
主DNS配置
set system services dhcp name-server 114.114.114.114
备DNS配置
set system services dhcp pool 10.30.0.0/24 address-range low10.30.0.10
set system services dhcp pool 10.30.0.0/24 address-range high10.30.0.254
地址池范围
set system services dhcp pool 10.30.0.0/24 router 10.30.0.1
地址池网关，同时也代表绑定网关所在VLAN
set interfaces vlan unit 201 familyinet address 10.30.0.1/24
配置VLAN地址
set vlans vlan201 vlan-id 201
创建VLAN
set vlans vlan201 l3-interfacevlan.201
添加VLAN三层接口。
