1、JUNIPEREX3200交换机配置JUNIPER EX3200交换机配置1 Ex3200开机指导开机后：login: rootLast login: Fri Jan 17 22:21:55 on ttyd0- JUNOS 7.2R3.3 built 2002-03-23 02:44:36 UTCTerminal type? vt100 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% cliroot2 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

2、以对设备进行各种参数的配置root configureeditroot#2.1 设置root用户密码命令：set system root-authentication plain-text-password路由器初始化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: labM7i_GZ# set system root-authentication plain-text-password New password:Retype new password:2.2 添加系统用户命令：set system login

3、 user juniper uid 2000 -设置用户名为juniper用户id为2000set system login user juniper class super-user -设置juniper用户为超级用户set system login user juniper authentication plain-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_GZ2.4 开启系统telnet服务命令：set system services telnet说明：系统默认是没有打开

4、telnet功能的，只有打开telnet服务之后才能从网络上登陆到路由器。2.5 设置交换机地址命令：Edit systemSet name-server 192.168.17.225Commit删除：Edit systemDelete name-server 192.168.17.2252.6 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到路由器。2.7 配置SNMPset snmp community authorization clients # 设置SNMP字符串set snmp t

5、rap-options source-address 192.168.1.1 #设置snmp trap的原地址为192.168.1.1set snmp contact #设置snmp的联系信息set snmp engine-id local #设置snmp v3 engine ID信息set snmp description #设置snmp的系统描述2.8 配置物理端口参数userhost#set interface ge-slot/pic/port description description#配置端口描述userhost#set interface ge-slot/pic/port mt

6、u mtu-number#配置端口MTUuserhost#set interface ge-slot/pic/port ether-options speed (10m | 100m | 1g)#配置端口速率userhost#set interface ge-slot/pic/port ether-options link-mode (automatic | full-duplex |half-duplex )#配置端口双工userhost#set interface ge-slot/pic/port ether-options (auto-negotiation |no-auto-negot

7、iation )#配置端口自动协商Example（例如）:roothost editEntering configuration modeeditroothost# set interfaces ge-3/0/0 description “to_BJ-4200-1”editroothost# set interfaces ge-3/0/0 mtu 9216editroothost# set interfaces ge-3/0/0 ether-options speed 1geditroothost# set interfaces ge-3/0/0 ether-options link-mode

8、full-duplexeditroothost# set interfaces ge-3/0/0 ether-options auto-negotiation2.9 配置物理端口二层接口editroothost# set interfaces ge-0/0/16 unit 0 family ethernet-switchingport-mode access配置物理端口作为二层access模式的接口，端口默认情况下就是二层access端口。edituserhost # show interfacesge-0/0/16 unit 0 family ethernet-switching;2.10

9、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editroothost# set interfaces ge-0/0/17 unit 0 family inet address192.168.20.1/242.11配置VLAN初始化配置时候，所有端口属于default VLAN，default vlan 的默认ID是0userhost# set interfaces name unit 0 family ethernet-switching port-mode access#配置端口的access模式，默认端口就是access模式。userhost

10、#set vlans vlan-name vlan-id number#配置VLAN分配vlan IDEX支持2种方式来配置access接口分配到VLAN，采用其中一种就可以实现端口VLAN的划分。方式一：userhost#set vlans vlan-name interface interface_name直接在VLAN中添加多个物理端口方式二：或是在物理接口下：userhost#set interfaces interface-name unit 0 family ethernet-switching vlan membersvlan-name or vlan-id#添加端口到特定VLA

11、Nuserhost# show vlans vlan-name detail#查看VLAN信息Example（例如）:roothost editEntering configuration modeeditroothost# set vlans sales vlan-id 100editroothost# set vlans sales interface ge-0/0/1#或者可以如下配置，实现相同的配置效果editroothost# set interfaces ge-0/0/1 unit 0 family ethernet-switchingvlan members sales2.12配

12、置Vlan trunk配置端口作trunk端口，支持802.1Q的标准封装。userhost# set interfaces name unit 0 family ethernet-switching port-mode trunk#配置端口的VLAN模式为trunk模式userhost# set interfaces name unit 0 family ethernet-switching vlan membersall|number#配置trunk端口的允许通过的VLAN，9.1版本目前不支持vlan-range，预期在9.2版本支持。Example:roothost editEnter

13、ing configuration modeeditroothost#showinterfaces ge-0/0/3 unit 0 family ethernet-switching port-mode trunk;vlan members orange blue ;ge-0/0/4 unit 0 family ethernet-switching port-mode trunk;vlan members 100 200 ;2.13配置 native-vlan-idEX在trunk端口下支持native-vlan 的配置：roothost editEntering configuration

14、modeeditroothost# set interface ge-0/0/8 unit 0 family Ethernet-switchnative-vlan-id purpleeditroothost#show interfacege-0/0/8 unit 0 family ethernet-switching port-mode trunk;vlan members orange blue purple ;native-vlan-id purple;2.14 静态路由协议手工添加到路由表下一跳必须有效所以的配置在routing-options 级别Syntax（语法）：editrouting-options static defaults static-options;route destination-prefix next-hop next-hop;qualified-next-hop address metric metric;preference preference;s
