VLAN非常规实验，给你带来一个不一样的VLAN2 查看本文前请先查看第一篇VLAN非常规实验，给你带来一个不一样的VLAN1https://90apt.com/2901本期为大家带来两个VLAN非常规实验1、傻瓜网络网管改造2、VLAN串联一、傻瓜网络网管改造 1、项目需求此需求来源真实，监控网络全部为傻瓜式连接交换机，需求逐步进行网管改造，改造应减小对监控网络的影响，监控网络可临时中断数分钟，不允许完全停机进行改造。2、改造前简化拓扑交换机均无配置，硬盘录像机与摄像头互通3、改造思路监控网络配置为vlan10，监控交换机管理网络配置为vlan20SW1 SW2 SW3 IP配置为192.168.20.1 192.168.20.2 192.168.20.3为保证监控不完全停机，需要用到trunk与pvid技术4、监控汇聚交换机改造将1-24口划入vlan10，将25-28划入trunk，配置vlan1 10 20通过，配置pvid10，为vlan20配置ip，最后测试硬盘录像机与摄像头是否互通[SW1]vlan 10 [SW1-vlan10]vlan 20 [SW1-vlan20]qu [SW1]int range g1/0/1 to g1/0/24 [SW1-if-range]port access vlan 10 [SW1-if-range]qu [SW1]int range g1/0/25 to g1/0/28 [SW1-if-range]port link-type trunk [SW1-if-range]port trunk permit vlan 1 10 20 [SW1-if-range]port trunk pvid vlan 10 [SW1]int vlan 20 [SW1-Vlan-interface20]ip add 192.168.20.1 24使用硬盘录像机ping摄像头[H3C]ping 192.168.1.2 Ping 192.168.1.2 (192.168.1.2): 56 data bytes, press CTRL_C to break 56 bytes from 192.168.1.2: icmp_seq=0 ttl=255 time=1.658 ms 56 bytes from 192.168.1.2: icmp_seq=1 ttl=255 time=2.110 ms5、技术解析在此改造中，为什么可以使用trunk接口对接无配置交换机并且不影响监控网络运行？此配置重点在于对vlan的理解，access接口为出撕标签入打标签，trunk接口默认不处理标签，当trunk接口配置pvid时，trunk接口对于此pvid的vlan同样具备access的作用，即出撕标签入打标签，因此trunk pvid vlan10可以与傻瓜交换机的access接口通讯，保证监控网络运行。6、其他监控交换机改造，测试监控交换机之间是否互通，测试硬盘录像机与摄像头是否互通[SW2]vlan 10 [SW2-vlan10]vlan 20 [SW2]int range g1/0/1 to g1/0/24 [SW2-if-range]port access vlan 10 [SW2-if-range]int range g1/0/25 to g1/0/28 [SW2-if-range]port link-type trunk [SW2-if-range]port trunk permit vlan 1 10 20 [SW2-if-range]port trunk pvid vlan 10 [SW2-if-range]qu [SW2]int vlan 20 [SW2-Vlan-interface20]ip add 192.168.20.2 24[SW3]vlan 10 [SW3-vlan10]vlan 20 [SW3-vlan20]qu [SW3]int range g1/0/1 to g1/0/24 [SW3-if-range]port access vlan 10 [SW3-if-range]int range g1/0/25 to g1/0/28 [SW3-if-range]port link-type trunk [SW3-if-range]port trunk permit vlan 1 10 20 [SW3-if-range]port trunk pvid vlan 10 [SW3-if-range]qu [SW3]int vlan 20 [SW3-Vlan-interface20]ip add 192.168.20.3 24硬盘录像机ping摄像头[H3C]ping 192.168.1.2 Ping 192.168.1.2 (192.168.1.2): 56 data bytes, press CTRL_C to break 56 bytes from 192.168.1.2: icmp_seq=0 ttl=255 time=1.230 ms 56 bytes from 192.168.1.2: icmp_seq=1 ttl=255 time=2.140 ms监控汇聚ping监控交换机3<SW1>ping 192.168.20.3 Ping 192.168.20.3 (192.168.20.3): 56 data bytes, press CTRL_C to break 56 bytes from 192.168.20.3: icmp_seq=0 ttl=255 time=1.000 ms 56 bytes from 192.168.20.3: icmp_seq=1 ttl=255 time=1.000 ms改造完成二、VLAN串联 1、项目需求此需求来源真实，SW1、SW2均为网管交换机，SW1 g1-g24为accessVLAN5 g25-g28为trunkALL，SW2 g1-g24为accessVLAN1 g25-g28为trunkALL，此时SW2所在区域已经封闭无法进入，请通过SW1的调整使服务器与读卡器互通。2、现状测试服务器无法ping通读卡器<H3C>ping 192.168.1.2 Ping 192.168.1.2 (192.168.1.2): 56 data bytes, press CTRL_C to break Request time out Request time out3、技术解析由于SW2无法操作，因此要在SW1上将VLAN5与VLAN1互联，通过VLAN1穿过trunk接口将数据送达读卡器，我们在SW1上创建一个VLAN1接口，将VLAN1与VLAN5接口通过网线串联。注意：我们是无法直接为端口配置VLAN1的，但可以通过default使接口恢复为VLAN1.[SW1-GigabitEthernet1/0/4]dis th # interface GigabitEthernet1/0/4 port link-mode bridge port access vlan 5 combo enable fiber # return [SW1-GigabitEthernet1/0/4]default This command will restore the default settings.
