ICT案例——网管中心

1. 注意点

• IRF堆叠技术
• 其他的配置类似园区网配置（点击跳转）

2. 架构

3. 配置

3.1 网关中心交换机配置IRF

这里把NMSW-IRF_9作为主设备，10作为从设备

主设备：

//先把物理端口关闭
[H3C]port group int t1/0/49 to t1/0/52
[H3C-if-range]shut
[H3C]dis int brief  //检查是否正确关闭

//把物理端口和逻辑端口绑定
[H3C]irf-port 1/1
[H3C-irf-port1/1]port group int t1/0/49
[H3C-irf-port1/1]port group int t1/0/50
[H3C-irf-port1/1]port group int t1/0/51
[H3C-irf-port1/1]port group int t1/0/52

//再重新打开物理端口，并保存配置
[H3C-irf-port1/1]int rang t1/0/49 to t1/0/52
[H3C-if-range]undo shut
[H3C-if-range]save
//激活配置
[H3C]irf-port-configuration active

从设备：

从设备只是多了一步修改成员编号的步骤，但是要注意修改完之后端口号的变化

//修改设备成员编号为2
[H3C]irf member 1 renumber 2
[H3C]qu
<H3C>reboot //注意reboot需要在用户界面下
<H3C>sys
[H3C]int rang t2/0/49 to t2/0/52 //注意这里端口已经是2开头了
[H3C-if-range]shut
[H3C]dis int brief  //检查是否正确关闭

//把物理端口和逻辑端口绑定
[H3C]irf-port 2/2
[H3C-irf-port1/1]port group int t2/0/49
[H3C-irf-port1/1]port group int t2/0/50
[H3C-irf-port1/1]port group int t2/0/51
[H3C-irf-port1/1]port group int t2/0/52

//再重新打开物理端口，并保存配置
[H3C-irf-port1/1]int rang t2/0/49 to t2/0/52
[H3C-if-range]undo shut
[H3C-if-range]save
//激活配置
[H3C]irf-port-configuration active

这里就已经配置完IRF了，现在修改设备名称会同步到从设备。

[H3C]sysn NMServ //按下回车
[NMServ]

3.2 把网关中心加入之前配置好的网络中

在NMServ上配置

//创建vlan，添加描述
[NMServ]vlan 50
[NMServ-vlan50]description NM50
[NMServ-vlan50]vlan 51
[NMServ-vlan51]description NM51

//接口添加描述
[NMServ-vlan51]int G1/0/48
[NMServ-GigabitEthernet1/0/48]description To_CSW01_G1/0/3
[NMServ-GigabitEthernet1/0/48]int G2/0/48
[NMServ-GigabitEthernet2/0/48]description To_CSW02_G1/0/3

//接口类型改trunk，允许vlan通过
[NMServ-GigabitEthernet2/0/48]int rang g1/0/47 g1/0/48
[NMServ-if-range]port link-type trunk 
[NMServ-if-range]port trunk permit vlan 50 51

//在NMServ上添加STP，把vlan51放到实例1中。
[NMServ]stp region-configuration 
[NMServ-mst-region]region-name NMServ
[NMServ-mst-region]instance 1 vlan 51
[NMServ-mst-region]active region-configuration 
[NMServ-mst-region]dis th

在核心路由器上配置

先配置CSW01

[CSW01]stp region-configuration 
[CSW01-mst-region]instance 1 vlan 51
[CSW01-mst-region]active region-configuration 
[CSW01]dis th

display this的结果
stp region-configuration
region-name h3c
instance 1 vlan 21 51
active region-configuration

[CSW02]stp region-configuration 
[CSW02-mst-region]instance 1 vlan 51
[CSW02-mst-region]active region-configuration 
[CSW02]dis th
