问题描述

 S6700 堆叠后配置多主检测功能,接口没有配置命令mad detect mode direct

[S6700-HJ-WH-A]int xg0/0/45  

[S6700-HJ-WH-A-XGigabitEthernet0/0/45]?     没有mad命令

处理过程
端口信息可以通过命令行查看:     显示信息可以看出 47、48口使能了堆叠功能

[S6700-HJ-WH-A]dis stack current-configuration
---------------current-configuration on slot 0 Begin---------------
stack enable
stack slot 0 renumber 0
stack slot 0 priority 200
stack reserved-vlan 4093
stack timer mac-address switch-delay 10

interface stack-port 0/1
port interface XGigabitEthernet0/0/47 enable

interface stack-port 0/2
port interface XGigabitEthernet0/0/48 enable

 

根因

  
即45~48为一组,如果其中两个端口绑定了堆叠口,相当于这一组的堆叠口都被同时使能成堆叠口了。而切换为堆叠口的端口是不能用作普通业务口的,不再支持DAD配置。

解决方案
把mad命令配置在非45~48一组的接口解决

 

建议与总结
当遇到此类问题,如果查询对应版本手册,是有此功能,那应该考虑是否在某些方面有限制,正如此问题,45~48为一组,如果其中两个端口绑定了堆叠口,相当于这一组的堆叠口都被同时使能成堆叠口了。而切换为堆叠口的端口是不能用作普通业务口的,不再支持DAD配置。这点需要注意。
