## Symptoms

- * rx_queue_0_csum_err incrementing in ethtool -S output
* **[Expert@gw]# ethtool -k <interface>** shows:   
  > **rx-checksumming: on**
* The interface is using the igb driver

## Cause

The cable or port in use may be faulty.

This can also be caused by the rx-checksumming option for the interface, in some cases.

**Background:** The TCP/UDP Checksum Offload (IPv4) function enables the adapter port to compute the checksum of transmitting IPv4 packets and verify the checksum of receiving IPv4 packets, taking load off from the CPU.
