H3C交换机堆叠简单案例

需求

由于网络规模迅速扩大，当前中心交换机（Device A）转发能力已经不能满足需求，需要另外增加一台设备Device B。现需要将两台设备配置IRF2堆叠，将网络转发能力提高一倍，并实现网络易管理、易维护。Device A和Device B分别使用自带的两个万兆口做堆叠口。也可以只用一个接口堆叠，根据实际情况而定。

网络拓补

实验思路

# Device A保留缺省编号为1，不需要进行配置。同时，在Device B上将设备的成员编号修改为2。

#配置堆叠口

#**DeviceA和DeviceB的IRF端口配置。

#IRF-port端口编号说明，irf-port 1/2中，第一个数字代表的是设备成员编号，第二个数字是接口编号。堆叠要求使用逻辑端口1对接逻辑端口2。即，如若第一台配置irf-port1/2，则第二台需要是用irf-port2/1对接。如若第一台使用irf-port1/1，则第二台需要配置irf-port2/2。

#设备配置好IRF2配置后，要先保存再**配置。

实验代码

DeviceA 

<H3C>system-view
System View: return to User View with Ctrl+Z.
[H3C]undo  info-center enable
Information center is disabled.
[H3C]sysname DeviceA //命名设备

[DeviceA]interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
//进入1/0/49-50 万兆口
[DeviceA-if-range]shutdown //将端口停止启动
[DeviceA-if-range]quit

[DeviceA]irf-port 1/2 //进入堆叠端口号 1/2
[DeviceA-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/49 //49端口加入组
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[DeviceA-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50//50端口加入组
[DeviceA-irf-port1/2]quit

[DeviceA]interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
[DeviceA-if-range]undo shutdown //启动两个万兆端口
[DeviceA-if-range]quit


[DeviceA]save force //保存
[DeviceA]irf-port-configuration active//**IRF端口配置

 

DeviceB 

<H3C>
<H3C>sy
System View: return to User View with Ctrl+Z.
[H3C]undo  info-center enable
Information center is disabled.
[H3C]sysname DeviceB
[DeviceB]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y

[DeviceB]quit
<DeviceB>reboot

Press ENTER to get started.
<DeviceB>system-view
System View: return to User View with Ctrl+Z.
[DeviceB]interface range Ten-GigabitEthernet 2/0/49 to t
[DeviceB]interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
[DeviceB-if-range]shutdown
[DeviceB-if-range]quit

[DeviceB]irf-port 2/1
[DeviceB-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/49
[DeviceB-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/50
[DeviceB-irf-port2/1]quit

[DeviceB]interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
[DeviceB-if-range]undo  shutdown
[DeviceB-if-range]quit


[DeviceB]save force

[DeviceB]irf-port-configuration active

总结

我们用命令display irf发现，Master(主要的)是DeviceA， Standby（备用的）是DeviceB

[DeviceA]display irf
MemberID    Role    Priority  CPU-Mac         Description
 *+1        Master  1         7ed0-4678-0104  ---
   2        Standby 1         7ed0-57d7-0204  ---
--------------------------------------------------
 * indicates the device is the master.
 + indicates the device through which the user logs in.

 The bridge MAC of the IRF is: 7ed0-4678-0100
 Auto upgrade                : yes
 Mac persistent              : 6 min
 Domain ID                   : 0
[DeviceA]

配置完成后，发现两台主机的系统命名都变成了“DeviceA”,因为A是主交换机，都以主交换机为主。

H3C交换机，上面有两种堆叠的方式

假如有三台设备，A,B,C

环叠：A接B，B接C，C接A

直连：A接B，B接C

初学堆叠，以后回来补充说明。
