Re: lots of input errors,help me

Hi,

You have a lots of input errors that denotes that its is a physical layer issue. You have to try replacing the cable connected to the port and talk to your TELCO as it might be a problem at their end. In most of the cases its the TELCO problem and You need to have the carrier do an end-to-end loopback test.

HTH, Please rate if it does.
