交换机irf堆叠怎么做bfd检测

常见为如下：

(8)     配置BFD MAD

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

[Sysname] vlan 3

[Sysname-vlan3] port gigabitethernet 1/0/1 gigabitethernet 2/0/1 

[Sysname-vlan3] quit

# 创建VLAN接口3，并配置MAD IP地址。

[Sysname] interface vlan-interface 3

[Sysname-Vlan-interface3] mad bfd enable

[Sysname-Vlan-interface3] mad ip address 192.168.2.1 24 member 1

[Sysname-Vlan-interface3] mad ip address 192.168.2.2 24 member 2

[Sysname-Vlan-interface3] quit

# 因为BFD MAD和生成树功能互斥，所以在GigabitEthernet1/0/1、GigabitEthernet2/0/1、GigabitEthernet3/0/1和GigabitEthernet4/0/1端口上关闭生成树协议。

[Sysname] interface gigabitethernet 1/0/1

[Sysname-gigabitethernet-1/0/1] undo stp enable

[Sysname-gigabitethernet-1/0/1] quit

[Sysname] interface gigabitethernet 2/0/1

[Sysname-gigabitethernet-2/0/1] undo stp enable

[Sysname-gigabitethernet-2/0/1] quit
