Juniper交换机更改端口vlan的过程
先列出交换机的配置:
show configuration | display set
看到30号端口信息如下:
set interfaces ge-0/0/30 unit 0 family ethernet-switching port-mode access
set interfaces ge-0/0/30 unit 0 family ethernet-switching vlan members 100
看到30号端口是在 vlan members 100
如何更改这个呢?
首先进入交换机的编辑模式:
edit
然后先删除原有的vlan:
delete interfaces ge-0/0/30 unit 0 family ethernet-switching vlan members 100
为了避免出错,保存我们刚刚输入的命令:
commit
然后写入新的 vlan:
set interfaces ge-0/0/30 unit 0 family ethernet-switching vlan members 101
然后在保存:
commit
每一次输入保存命令之后会提示:
configuration check succeeds
commit complete
创建vlan
(1) 创建一个VLAN,指定VLAN名称和ID号
set vlans vlan vlan-id 10
(2) 将交换机端口修改为access模式加入到新创建的VLAN中
set interfaces ge-0/0/2 unit 0 family ethernet-switching port-mode access
set interfaces ge-0/0/2 unit 0 family ethernet-switching vlan members 2061
(3) 创建3层VLAN子端口,并且将子端口和VLAN关联:
set interfaces vlan unit 10 family inet address 192.168.1.1/24
set vlans vlan interface vlan.10 //vlan子端口和VLAN对应起来
wildcard range set interfaces ge-0/0/[11-13,16,23,45] unit 0 family ethernet-switching vlan members v500
wildcard range set interfaces ge-0/0/[1-45] unit 0 family ethernet-switching vlan members 10
查看mac地址和接口的对应关系
show ethernet-switching table brief
查看vlan及接口情况 *表示物理、逻辑上可达(能ping通)
show vlan
查看路由表
show route
查看所有接口运行 状态
show interfae terse
查看系统日志
show log messages
查看接口运行状态
show interface ge-x/y/z detail
查看arp表
show arp
查看硬件板卡当前状态(温度等信息)
show chassis environment

mac地址绑定
set ethernet-switching-options secure-access-port interface ge-0/0/1.0 mac-limit 1
set ethernet-switching-options secure-access-port interface ge-0/0/1.0 mac-limit action drop
set ethernet-switching-options secure-access-port interface ge-0/0/1.0 allowed-mac
trunk
1:set vlans changzhoudaxuevlan vlan-id 1801
2:set interfaces xe-1/0/2 unit 0 family ethernet-switching port-mode trunk
3:set interfaces xe-1/0/2 unit 0 family ethernet-switching vlan members changzhoudaxuevlan
4:set interfaces vlan unit 1801 family inet6 address 2001:da8:a3:d001::1/64
5:set vlans changzhoudaxuevlan l3-interface vlan.2001 (关联vlan和三层接口)
juniper冲突解决
1、首先show arp 找到对应的ip和mac
2、然后 show ethernet-switching table 找到对应的接口
3、接着干掉该接口
4、最后在dhcp下面去绑定ip地址和mac地址
set system services dhcp static-binding 08:ed:b9:e2:8a:89 fixed-address 192.168.1.5
输入用户名、密码
进入cli模式
进入配置模式
2月9日 重置juniper交换机,启用管理页面
设置密码后:
set interfaces me0 unit 0 family inet address 192.168.2.200/24
set system services telnet
set system services web-management http

端口启用与禁用
启用 #delete interfaces ge-0/0/22 disable
禁用 #set interfaces ge0/0/22 disable
查看接口状态
show interaces ge-0/0/22
