问题描述：

V7两台105做堆叠，现场做了BFD MAD检测，

vlan 1111
 description "xintiao"

interface Vlan-interface1111
 mad bfd enable
 mad ip address 20.20.20.1 255.255.255.0 member 1
 mad ip address 20.20.20.2 255.255.255.0 member 2

interface GigabitEthernet1/5/0/48
 port link-mode bridge
 description to_bfd
 port access vlan 1111

interface GigabitEthernet2/5/0/48
 port link-mode bridge
 description to_bfd
 port access vlan 1111

现在看到两个BFD接口下outpu流量跑满，

BFD所用的VLAN不能在其他接口上允许，尤其是Trunk，同时要关闭生成树功能。

BFD MAD与生成树功能互斥，关闭STP试试呢？

STP未开启

dis vlan 1111看下？是否还有别的端口放通vlan 1111了？

VLAN ID: 1111 VLAN type: Static Route interface: Configured IPv4 address: 20.20.20.1 IPv4 subnet mask: 255.255.255.0 Description: "xintiao" Name: VLAN 1111 Tagged ports: None Untagged ports: GigabitEthernet1/5/0/48 GigabitEthernet2/5/0/48 没有，就这两个端口
