思科3850接口output方向有大量的error包,如下:
GigabitEthernet3/0/31 is up, line protocol is up (connected)
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
731053897 output errors, 0 collisions, 0 interface resets
0 unknown protocol drops
GigabitEthernet3/0/32 is up, line protocol is up (connected)
2 input errors, 1 CRC, 0 frame, 0 overrun, 0 ignored
22627844 output errors, 0 collisions, 0 interface resets
0 unknown protocol drops
GigabitEthernet3/0/33 is up, line protocol is up (connected)
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
1948027 output errors, 0 collisions, 0 interface resets
0 unknown protocol drops
GigabitEthernet3/0/34 is up, line protocol is up (connected)
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
19279973 output errors, 0 collisions, 0 interface resets
0 unknown protocol drops
只有Output的方向有error,但我show cdp neighbor后,与error包连接着的对端交换机的接口没有error包
但业务是正常的,我们这里有几台思科3850接口下都存在着error包的现象,
接口下自动协商也没有指定speed,但长ping下面的业务也正常,就是output方向有error包
请问大佬们为什么会这样呢?望大神指点
