Re: FastEthernet0/0 26304304 input errors - need help

Alexander Tsirkunov · ‎06-28-2020

Hello all, need help with some problem on eth 0/0 i'ts burn my ...s averyday. (26304304 input errors)

Connection stable, no problems with physycs level, no problem with upload and download data, but I still want to beat this problem. Sometimes messages come from zabbix, that the problem has been successfully resolved, but in just a couple of minutes, it appears again. I was clear counters, but it's can't help me issue this troble. I reset error counters, but this is only a temporary solution.

Is the port's speed and duplex hard-coded?

Post the complete output to the following command:

sh controll e f0/0

Is FastEthernet 0/0 port hard-coded with duplex and speed settings?

If it is, why?
