c3850:interfaces had lots of output errors

Hello guys,

C3850 interfaces had lots of output error 

Here is the show interface output:

C3850#sho interfaces | in protocol | 5 minute | error

......................

 

Although there are lots of output errors, but the network function is normal.

 

thanks,

1. Post the complete output to the "sh interface <PORTS>".
2. What IOS-XE version is the switch (stack) running on?

Dear Leo:

Thank you for you reply

Raise a TAC Case. I believe this is a very well-known bug, CSCvb65304.

Thank you Leo
