Hi sameer
you can check the inerrors parameters, the same value as your CRC error, so this is physical layer error, so maybe you can check the ethernet port attribute as auto negotiated between switch and device.
HI,Thank you for you reply .
both side the duplex is same ( auto ) and switch and ptp_450 reading fullduplex and speed 100 .
we even changed the cable between IDU and switch ,but still problem same .
please advice . will outdoor cable issue give CRC error .
HI,
At last after troubleshoot for more than a week ,we solved issue of crc error and Input error . its was mainly surger compressor which is connected in between the radio and switch was faulty and also we replaced the connector at the radio side .
