H3C S7006X-LSCZ17006X-以太网交换机主机虚拟化双活配置

irf2就是虚拟化，也就是双活，两台虚拟成1台

您好，请知：

如果是要使用IRF对多个物理设备虚拟成一台，以下是配置参考举例：

1.9  IRF典型配置举例

1.9.1  IRF典型配置举例（LACP MAD检测方式）

1. 组网需求

如图1-15所示，配置Device A和Device B组成IRF设备。由于IRF到中间设备Device C有跨成员设备的聚合链路，且Device C为支持LACP协议的H3C设备，我们配置LACP MAD进行分裂检测。

3. 配置步骤

(1)     配置Device A

# 配置Device A的成员编号为1，创建IRF端口2，并将它与物理端口Ten-GigabitEthernet2/0/1和Ten-GigabitEthernet3/0/1绑定。

<Sysname> system-view

[Sysname] irf member 1

[Sysname] irf-port 2

[Sysname-irf-port2] port group interface ten-gigabitethernet 2/0/1

[Sysname-irf-port2] port group interface ten-gigabitethernet 3/0/1

[Sysname-irf-port2] quit

# 将当前配置保存到下次启动配置文件。

[Sysname] quit

<Sysname> save

# 将设备的运行模式切换到IRF模式。

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot. Continue? [Y/N]:y

You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Saved the current configuration to mainboard device successfully.

Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

设备重启后Device A组成了只有一台成员设备的IRF。

(2)     配置Device B

# 配置Device B的成员编号为2，创建IRF端口1，并将它与物理端口Ten-GigabitEthernet2/0/1和Ten-GigabitEthernet3/0/1绑定。

<Sysname> system-view

[Sysname] irf member 2

[Sysname] irf-port 1

[Sysname-irf-port1] port group interface ten-gigabitethernet 2/0/1

[Sysname-irf-port1] port group interface ten-gigabitethernet 3/0/1

[Sysname-irf-port1] quit

# 将当前配置保存到下次启动配置文件。

[Sysname] quit

<Sysname> save

# 参照图1-15进行物理连线。

# 将设备的运行模式切换到IRF模式。

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot. Continue? [Y/N]:y

You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Saved the current configuration to mainboard device successfully.

Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

设备B重启后与设备A形成IRF。

(3)     配置LACP MAD检测

# 设置IRF域编号为1。

<Sysname> system-view

[Sysname] irf domain 1

# 创建一个动态聚合接口，并开启LACP MAD检测功能。

[Sysname] interface bridge-aggregation 2

[Sysname-Bridge-Aggregation2] link-aggregation mode dynamic

[Sysname-Bridge-Aggregation2] mad enable

You need to assign a domain ID (range: 0-4294967295)

[Current domain ID is: 1]:

The assigned domain ID is: 1

[Sysname-Bridge-Aggregation2] quit

# 在聚合接口中添加成员端口Ten-GigabitEthernet1/2/0/2和Ten-GigabitEthernet2/2/0/2，专用于Device A和Device B实现LACP MAD检测。

[Sysname] interface ten-gigabitethernet 1/2/0/2

[Sysname-Ten-GigabitEthernet1/2/0/2] port link-aggregation group 2

[Sysname-Ten-GigabitEthernet1/2/0/2] quit

[Sysname] interface ten-gigabitethernet 2/2/0/2

[Sysname-Ten-GigabitEthernet2/2/0/2] port link-aggregation group 2

(4)     配置中间设备Device C

Device C作为中间设备来转发、处理LACP协议报文，协助Device A和Device B进行多Active检测。从节约成本的角度考虑，使用一台支持LACP协议扩展功能的设备即可。

# 创建一个动态聚合接口。

<Sysname> system-view

[Sysname] interface bridge-aggregation 2

[Sysname-Bridge-Aggregation2] link-aggregation mode dynamic

[Sysname-Bridge-Aggregation2] quit

# 在聚合接口中添加成员端口Ten-GigabitEthernet1/0/1和Ten-GigabitEthernet1/0/2，用于帮助LACP MAD检测。

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] port link-aggregation group 2

[Sysname-Ten-GigabitEthernet1/0/1] quit

[Sysname] interface ten-gigabitethernet 1/0/2

[Sysname-Ten-GigabitEthernet1/0/2] port link-aggregation group 2
