What does this error output on my interfaces mean ?

Hi,

I have been monitoring my wan interfaces and lan interfaces tcp_udp_csum_error, Rx_CRC_errors, RX_internal_mac_error counters  have all been incrementing. What does this output mean ?

Check the duplex/speed on both sides of the WAN connection.  If you are getting tcp_udp_csum_errors then it means the hardware accelerator is dropping packets.

I'd also consider to replace or re-seat the cable
