S5130S-52S-HI 配置3台堆叠

SW1:

#

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 

其余两台也参考上述配置，请问MAD检测应该怎么配置呢？

sw1（mad检测配置）：

interface Vlan-interface205

 description MAD

 mad bfd enable

 mad ip address 205.205.205.1 255.255.255.0 member 1

 mad ip address 205.205.205.2 255.255.255.0 member 2

 mad ip address 205.205.205.3 255.255.255.0 member 3

#

interface GigabitEthernet1/0/48

 port link-mode bridge

 port access vlan 205

 undo stp enable

#

interface GigabitEthernet2/0/48

 port link-mode bridge

 port access vlan 205

 undo stp enable

#

interface GigabitEthernet3/0/48

 port link-mode bridge

 port access vlan 205

 undo stp enable

是不是SW1的g1/0/48口和SW2的G2/0/47口接上，然后SW1的g1/0/47与SW3的g3/0/48接上，SW3的g3/0/47和SW2的g2/0/48接上

还是：sw1的g1/0/48和sw2的g1/0/47接上，sw2的g1/0/48和sw3的g1/0/48接上
