lacp with stp实验问题

gallonli

配置如下，感觉配置应该没问题啊，但是port channel没有成功，switchA的配置一样就不帖了（只是模式是active），好像关键是在port-channel下配完swi mode tru之后，跳了这么一条log“%EC-5-CANNOT_BUNDLE2: Fa0/3 is not compatible with Po1 and will be suspended (dtp mode of Fa0/3 is on, Po1is off )

%EC-5-CANNOT_BUNDLE2: Fa0/4 is not compatible with Po1 and will be suspended (dtp mode of Fa0/4 is on, Po1is off )”

网上查说是因为fa0/3的mode和port-channel的mode不一样导致的，但是看配置可以看出来端口和port-channel我都配了啊，是什么问题导致port-channel没建起来呢，是模拟器的问题吗？

把接口shutdown然后敲switchport nonegotiate把DTP关掉试试看

你把这句自己翻译出来看看是啥意思吧

我知道是DTP mode，但是如楼上我的配置有问题吗？没找到啊
