RX packet errors
I am getting a lot of RX errors in my server and the network connection is very low, around 6kB/s. I am giving the NIC details below.
The eth0 is the onboard NIC, its a RTL8201EL. That NIC is a 10/100 NIC. The cable is about 250m long and it cat 6e. It connects a Juniper ex3200 to a Netgear 108E (link at 1gb) and then from the netgear to the server. Our network admin told me that he did test the cable and and it did not give any errors.
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:221283920 (211.0 MiB) TX bytes:36979981 (35.2 MiB)

Can anybody please help me to find the root cause of this issue.
250m is way outside the specs.
Afaik 100m is maximum and even then lower throughput is expected.You must always face the curtain with a bow.
Anything over 100m is definitively not supported. Are you sure it is 250m and not 250ft?
I also question how your network admin could check such a long cable and tell you it is fine.
The adventure of a life time.

Not adding much here, but if it's really 250m then you are exceeding spec by 2.5 times, if the cable is really that long the only way to fix this is to place signal regenerators (or a small switch or hub) no more than at 100m intervals, so essentially you would need 2 in a run of 250m.
