因ensp做不了堆叠，所以用了华三的模拟器HCL，下载地址：H3C网络设备模拟器官方免费下载-新华三集团-H3C

        拓朴如下：

        1、堆叠配置步骤如下：

        1、S1和S2配置堆叠过程：

[S1]
irf domain 1
irf member 1 priority 32
#
int Ten-GigabitEthernet1/0/49
shutdown
int Ten-GigabitEthernet1/0/50
shutdown
#
irf port 1/1
port group int Ten-GigabitEthernet1/0/49
port group int Ten-GigabitEthernet1/0/50
#
int range  Ten-GigabitEthernet1/0/49 to  Ten-GigabitEthernet1/0/50
undo shutdown
#
[S2]
irf domain 1
irf member 1 renumber 2
#
save force
reboot
#
int range  Ten-GigabitEthernet1/0/49 to  Ten-GigabitEthernet1/0/50
shutdown
#
irf port 2/2
port group int Ten-GigabitEthernet1/0/49
port group int Ten-GigabitEthernet1/0/50
#
int range  Ten-GigabitEthernet1/0/49 to  Ten-GigabitEthernet1/0/50
undo shutdown
#
[S1]
irf-port-configuration active
#
[S2]
irf-port-configuration active
#

        2、验证堆叠：

        这时，在S2上看 irf 配置，设备名已经变成S1，即和Master设备名称相同：

        S1上：

        3、接着配聚合口：

[S3]
int Vlan-interface 1
ip addr 10.1.1.254 24
#
int Bridge-Aggregation 1link-aggregation mode dynamic
#
interface GigabitEthernet1/0/1port link-aggregation group 1
#
interface GigabitEthernet1/0/2port link-aggregation group 1
#

        S1配置相同

        4、查看聚合口状态：

        5、验证：

        PC1 和 PC2 分别 ping 网关正常
