N5k Log message

[rtjensen4]

Hi All,

I'm getting this strange Log Message on my Nexus 5548 switch. I have a pair of them connected together and I'm using VPC. The other switch is not displaying this message. Any ideas?

2011 May 26 08:24:07 HQ-N5k-1 %AUTHPRIV-3-SYSTEM_MSG: ttyS0: input overrun - getty[1803]
2011 May 26 08:24:27 HQ-N5k-1 %AUTHPRIV-3-SYSTEM_MSG: ttyS0: input overrun - getty[1816]
2011 May 26 08:24:46 HQ-N5k-1 %AUTHPRIV-3-SYSTEM_MSG: ttyS0: input overrun - getty[1829]

These were recently installed and I have been seeing the message since I installed them.

Version:

System version: 5.0(3)N1(1b)

Authpriv is usually tied around AAA and ttyS0 is a serial interface so it appears that it is possibly a mis-match of serial port settings on a device that is trying to console into it but I could be completely wrong.

Thanks, but I don't think that's the case. The only Serial interface is the Console port, and there's nothing connected to it. The error occurs every 20-30 seconds.

I saw this issue once after reloading the switch. and the issue cleared after unplugging the console cable and plug the cable back.

you may also want to change the speed of the line console to match both sides.

if console is not needed, unplug any cable in this port
