创建VLAN
set vlans name vlan-id xx
配置VLAN的L3接口地址
set vlans name
set interface vlan xx unit xx family inet /24
将某个交换端口添加到创建好的VLAN中
set interface ge-0/0/x unit 0 family ethernet-switching port-mode access vlan members name
配置TRUNK端口
set interface ge-0/0/23 unit 0 family ethernet-switchi
ng port-mode trunk native-vlan-id 1 vlan member xx
配置冗余RE组
set groups re0 system host-name GZ_LAB_M10i_1_RE0
set groups re0 interfaces fxp0 unit 0 family inet address 172.27.69.34/24

配置VRF并绑定3层VLAN 接口
set routing-instances vrf-1 instance-type vrf
set routing-instances vrf-1 interface vlan.10
set routing-instances vrf-1 route-distinguisher 65000:100
set routing-instances vrf-1 vrf-target target:65000:100
set routing-instances vrf-2 instance-type vrf
set routing-instances vrf-2 interface vlan.20
set routing-instances vrf-2 route-distinguisher 65000:200
set routing-instances vrf-2 vrf-target target:65000:200
show route ter  可以看到路由分类
配置各VRF到PE的路由分别以OSPF和静态举例：=================================================
set routing-instances vrf-1 instance-type vrf
set routing-instances vrf-1 interface vlan.10
set routing-instances vrf-1 route-distinguisher 65000:100
set routing-instances vrf-1 vrf-target target:65000:100

配置EX交换机上行TRUNK端口的冗余，假设该EX有两个GE上行到两台汇聚层或核心层交换机，===========================
这两个端口都配置为TRUNK 并作为redundant trunk group 时将不再考虑STP的问题
[edit]
set ethernet-switching-options redundant-trunk-group group-name group1
set ethernet-switching-options redundant-trunk-group group-name group1 interface ge-0/0/9.0 primary
set ethernet-switching-options redundant-trunk-group group-name group1 interface ge-0/0/10.0
配置完成后检查：

EX 3200 系列交换机还提供完整的端口安全特性，包括DHCP
Snooping（动态主机配置协议侦听）、DAI（动态ARP检测）和MAC
限制来抵御内外部侦听、中间人攻击和拒绝服务(DoS)攻击。
安全性
● MAC 地址限制
● 允许的MAC 地址数——可逐端口配置
● 动态 ARP 检测（DAI）
● 本地代理ARP
● 静态ARP 支持
● DHCP 侦听
访问控制表（ACL）（JUNOSTM 防火墙过滤器）
● 基于端口的ACL（PACL）——入口
● 基于VLAN 的ACL（VACL）——入口和出口
● 基于路由器的 ACL（RACL）——入口和出口
● 每个系统在硬件中支持的ACL 条目（ACE）
：7,000
● 用于计算被拒绝的数据包的ACL 计算器
● 用于计算获准数据包的ACL 计算器
● 能够在列表中间添加/ 删除/ 更改ACL 条目（ACL 编辑）
● L2-L4 ACL
● 基于802.1X 端口
● 802.1X 多个请求方
● 采用VLAN 分配机制的802.1X
● 采用验证旁路接入机制的802.1X（基于主机MAC 地址）
● 支持VoIP VLAN 的802.1X
● 基于RADIUS 属性的802.1X 动态ACL
● 802.1X 支持的EAP 类型：MD5，TLS，TTLS，PEAP
● MAC 验证（本地）
● 控制平面DoS 防御
配置EX交换机的port-securit 及DHCP Snooping 端口的MAC限制绑定MAC地址：==================================
DAI保护EX系列交换机不被 ARP欺骗，同时保护在局域网中DHCP侦听数据库的 ARP缓存不 被攻击。
[edit ethernet-switching-options secure-access-port]
端口的MAC地址数限制
set interface ge-0/0/1 mac-limit 4 action drop
端口的MAC地址绑定
set interface ge-0/0/2 allowed-mac 00:05:85:3A:82:80
set interface ge-0/0/2 allowed-mac 00:05:85:3A:82:81
set interface ge-0/0/2 allowed-mac 00:05:85:3A:82:83
set interface ge-0/0/2 allowed-mac 00:05:85:3A:82:85
set interface ge-0/0/2 allowed-mac 00:05:85:3A:82:88
set interface ge-0/0/2 mac-limit 4 action drop
配置到DHCP服务器连接端口的信任
set interface ge-0/0/8 dhcp-trusted
配置在需要做端口安全的VLAN加入防止DHCP欺骗参数及在该VLAN中MAC移动的限制：
关喆资料set vlan employee–vlan arp-inspection    DAI的配置
set vlan employee-vlan examine-dhcp
set vlan employee-vlan mac-move-limit 5 action drop
配置完成检查：
user@switch> show dhcp snooping binding
user@switch> show arp inspection statistics 检查交换机上DAI 的工作情况
user@switch> show ethernet-switching table
配置EX交换机的RSTP功能 ：===========================================

user@switch1# set voice-vlan vlan-id 10
user@switch1# set employee-vlan description “Employee VLAN”
user@switch1# set employee-vlan vlan-id 20
