最近出现一个问题,思科设备和华为设备互联。都是三层,万兆接口。最近思科交换机互连口出现橘黄色灯闪烁(之前是绿灯),并且有unknown protocols drops。光衰正常,端口速率协商一致都是万兆。正常通信,ping几乎不丢包(之前ping1000个包都没丢)。这是个什么问题啊,求解答。
接口配置如下:
思科交换机:
TenGigabitEthernet1/0/47 is up, line protocol is up (connected)
Hardware is Ten Gigabit Ethernet, address is 0431.1003.ef55 (bia 0431.1003.ef55)
