物理拓扑
堆叠的接口最好是千兆光口
单模传输距离会更远，多模传输距离近
模块型号里SM表示单模，MM表示多模
规划说明
| 设备 | IRF接口 | 物理接口 |
|---|---|---|
| Master | irf-port 1/1 | XG1/0/49 |
| Master | irf-port 1/2 | XG1/0/50 |
| Slave1 | irf-port 2/1 | XG2/0/49 |
| Slave1 | irf-port 2/2 | XG2/0/50 |
| Slave2 | irf-port 3/1 | XG3/0/49 |
| Slave2 | irf-port 3/2 | XG3/0/50 |
Master优先级配置为10，两个从设备优先级配置为1
配置
主交换机
配置完IRF接口重新启用物理接口后，需要先save保存，再使irf配置生效
interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
shutdown
#
irf member 1 priority 10
irf member 2 priority 1
irf member 3 priority 1
#
irf-port 1/1
port group interface Ten-GigabitEthernet 1/0/49
irf-port 1/2
port group interface Ten-GigabitEthernet 1/0/50
#
interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
undo shutdown
#
save
#
irf-port-configuration active
可以先将物理接口shutdown，等两台从设备配置完成后，再undo shutdown
从交换机1
修改板卡的序列号，修改后需要重启生效
irf member 1 renumber 2
save
y
y
reboot
配置IRF接口
配置完成后，同样先save再使IRF配置生效
#
interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
shutdown
#
irf-port 2/1
port group interface Ten-GigabitEthernet 2/0/49
irf-port 2/2
port group interface Ten-GigabitEthernet 2/0/50
#
interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
undo shutdown
#
save
#
irf-port-configuration active
从交换机2
irf member 1 renumber 3
save
y
y
reboot
#
interface range Ten-GigabitEthernet 3/0/49 to Ten-GigabitEthernet 3/0/50
shutdown
#
irf-port 3/1
port group interface Ten-GigabitEthernet 3/0/49
irf-port 3/2
port group interface Ten-GigabitEthernet 3/0/50
#
interface range Ten-GigabitEthernet 3/0/49 to Ten-GigabitEthernet 3/0/50
undo shutdown
#
save
#
irf-port-configuration active
配置完成并激活IRF配置后，从设备会自动重启，所以再使堆叠配置生效前，需要先保存配置。或最后连线
如果设备没有重启，检查是否是主设备上的堆叠物理接口shutdown
验证
堆叠配置完成后，会看到成员设备
+表示当前登录的设备
保存配置时，会自动保存到Solt 2和Solt 3
