Incoming Errors (IncomingErrors)

This parameter displays the percentage of incoming data packets that contain packet format errors. A large number of incoming data packets with format errors usually indicates faulty hardware on the network. Another possibility is that your system's device driver cannot receive packets fast enough.

The following formula is used to calculate the Incoming Error Percent:

IncomingErrors= (DELTAIerrs/DELTAIpkts) * 100

where,

• DELTAIerrs = difference in "errors" value in "RX" line from ifconfig, difference calculated using values from two consecutive collections.
• DELTAIpkts = IncomingPackets value

Recommendations

Determine if the problem is local or elsewhere on the network by using the spray command. (You should only use the spray command during non-peak times due to the load this command places on your network.) If the problem is local to your system, the problem could be a faulty network card, or your network card may not be able to handle the capacity. In either case, you should replace your network card with one that can handle the needed capacity. If the problem is elsewhere in the network, you need to track down and replace the faulty hardware. No range thresholds have been set for this parameter. Your experience with your system and network should help you determine useful range thresholds.
