7506E-X做堆叠

1、配置IRF堆叠

1号设备关键配置如下：

[H3C]irf member 1 renumber 1 //将1号设备设定为成员1

[H3C]irf member 1 priority 32 //配置优先级32，值大优先，范围（1-32）

[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51

[H3C-if-range]shutdown

[H3C-if-range]quit


[H3C]irf-port 1/2 //将物理端口绑定到IRF端口

[H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50

[H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/51

[H3C-irf-port1/2]quit


[H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51

[H3C-if-range]undo shutdown

[H3C-if-range]quit

[H3C]irf-port-configuration active //激活IRF

[H3C]save


2号设备关键配置点如下：


[H3C]irf member 1 renumber 2 //将2号设备设定为成员2

[H3C]irf member 1 priority 1 //配置优先级1

[H3C]int range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51

[H3C-if-range]shutdown

[H3C-if-range]quit

[H3C]irf-port 2/1 //将物理端口绑定到IRF端口

[H3C-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/50

[H3C-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/51

[H3C-irf-port2/1]quit


[H3C]int range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51

[H3C-if-range]undo shutdown

[H3C-if-range]quit

[H3C]save

[H3C]irf-port-configuration active //激活IRF







2、配置LACP MAD检测


[H3C] irf domain 1 //设置IRF域编号为1。

[H3C] interface bridge-aggregation 2 //创建一个动态聚合接口，并使能LACP MAD检测功能。

[H3C-Bridge-Aggregation2] link-aggregation mode dynamic

[H3C-Bridge-Aggregation2] mad enable

[H3C-Bridge-Aggregation2] quit


# 在聚合接口中添加成员端口GigabitEthernet1/0/1、GigabitEthernet2/0/1，用于实现LACP MAD检测。

[H3C] interface range gigabitethernet 1/0/1 gigabitethernet 2/0/1

[H3C-if-range] port link-aggregation group 2

[H3C-if-range] quit

[H3C-if-range] save f


配置中间设备

中间设备用来来转发、处理LACP协议报文，协助IRF中的四台成员设备进行多Active检测。从节约成本的角度考虑，使用一台支持LACP协议扩展功能的交换机即可


[H3C] interface bridge-aggregation 2

[H3C-Bridge-Aggregation2] link-aggregation mode dynamic

[H3C-Bridge-Aggregation2] quit


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

[H3C] interface range gigabitethernet 1/0/1 to gigabitethernet 1/0/4

[H3C-if-range] port link-aggregation group 2

[H3C-if-range] quit

[H3C-if-range] save f








3、配置BFD MAD检测

irf link-delay 0 #修改IRF链路down延迟上报时间为0。

# 创建VLAN 3，并将端口GigabitEthernet1/0/1、GigabitEthernet2/0/1加入VLAN 3中。

vlan 3

port gigabitethernet 1/0/1 gigabitethernet 2/0/1

quit


# 创建VLAN接口3，并配置MAD IP地址。

interface vlan-interface 3

mad bfd enable

mad ip address 192.168.2.1 24 member 1

mad ip address 192.168.2.2 24 member 2

quit


# 因为BFD MAD和生成树功能互斥，所以在GigabitEthernet1/0/1、GigabitEthernet2/0/1端口上关闭生成树协议。

interface range gigabitethernet 1/0/1 gigabitethernet 2/0/1

undo stp enable

quit



配置中间设备 //如果没有中间设备的话，此配置可不配

中间设备用来透传BFD MAD报文，协助IRF中的四台成员设备进行多Active检测。


# 创建VLAN 3，并将端口GigabitEthernet1/0/1～GigabitEthernet1/0/4加入VLAN 3中，用于转发BFD MAD报文。

[H3C] vlan 3

[H3C-vlan3] port gigabitethernet 1/0/1 to gigabitethernet 1/0/4

[H3C-vlan3] quit

[H3C-vlan3] save f
