juniper configuration case

access

access接口绑定vlan：

root# set vlans vlan10 vlan-id 10 description vlan10

root# set interfaces ge-0/0/10 unit 0 family ethernet-switching interface-mode access

root# set interfaces ge-0/0/10 unit 0 family ethernet-switching vlan members vlan10

trunk

trunk接口放行vlan：

root# set interfaces ge-0/0/20 unit 0 family ethernet-switching interface-mode trunk

root# set interfaces ge-0/0/20 unit 0 family ethernet-switching vlan members all

ae

链路捆绑

root# set chassis aggregated-devices ethernet device-count 2 ------> 2是指聚合口可以同时捆绑多少物理接口，1-64

root# set interfaces xe-0/2/0 ether-options 802.3ad ae0 ------> ae0是聚合口的名字

root# set interfaces xe-0/2/1 ether-options 802.3ad ae0

root# set interfaces ae0 aggregated-ether-options lacp active

注：

xe-0/2/0 指的是堆叠中的member 0的2号插槽的0号端口

vlan网关

root# set vlans vlan30 vlan-id 30 description vlan30

root# set interfaces irb unit 30 family inet address 192.168.30.254/24

root# set vlans vlan30 l3-interface irb.30

物理接口二转三

默认情况下，电口都是二层的，如果需要转换成三层，需要提前删除接口下默认的二层配置

root# edit interfaces ge-0/0/40

root# delete unit 0 family ethernet-switching

root# exit

root# edit protocols rstp

root# delete interface ge-0/0/40

root# exit

root# set interfaces ge-0/0/40 unit 0 family inet address 192.168.40.1/24

需要提前删除默认配置，否则会出现如下报错

root# set interfaces ge-0/0/40 unit 0 family inet address 192.168.40.1/24

root# edit interfaces ge-1/0/40 

{master:1}[edit interfaces ge-1/0/40]
root# show

    family ethernet-switching {
        interface-mode access;

物理接口三转二

三层接口上配置有IP地址 unit 0 family inet address，所以直接delete，就可以变成二层接口了

root# delete interfaces ge-1/0/40 unit 0

示例

root# edit interfaces ge-1/0/40 

{master:1}[edit interfaces ge-1/0/40]
root# show          
unit 0 {
    family inet {
        address 192.168.40.254/24;
    }
}

{master:1}[edit interfaces ge-1/0/40]
root# delete unit 0 

{master:1}[edit interfaces ge-1/0/40]
root# show             

{master:1}[edit interfaces ge-1/0/40]
root# exit 

{master:1}[edit]

验证

二层access设置成功

root# set interfaces ge-1/0/40 unit 0 family ethernet-switching interface-mode access           

{master:1}[edit]
root# set interfaces ge-1/0/40 unit 0 family ethernet-switching vlan members vlan10

光堆叠

相比用堆叠线缆进行堆叠，多出来的一个步骤为

指定某两个光口作为堆叠口，这样在这个光口上插上的光纤就可以作为堆叠线缆使用了

光口板卡插上，先指定某个光口为堆叠口

root> request virtual-chassis vc-port set pic-slot 2 port 0 member 0 -----> 2号插槽，0号端口，member号为0

root> request virtual-chassis vc-port set pic-slot 2 port 0 member 1

指定完后在member 0上进行常规的堆叠配置，绑定member成员
