Hello Ilan
The OutDiscard errors shown here on your interfaces indicate that packets are being dropped from the output queue on the interface. This may occur for many different reasons. These include:
- Bandwidth congestion - There may be more traffic attempting to egress the interface than the interface can handle. This can be either due to an increase in network traffic or a misconfigured traffic shaping policy, or a mismatch between ingress and egress interface traffic speeds.
- High CPU utilization - If the CPU is under heavy load, it may simply drop some packets because it is unable to process them.
- Buffer issues - If the buffer is configured to be too small, or if it is not configured properly, it could result in OutDiscards.
- QoS configuration - An incorrect QoS configuration or policy map may cause packets to be dropped from the output queue if they don’t conform to specific criteria.
- Duplex mismatch - A duplex mismatch can result in such output discards.
Hopefully, these points will help you in your troubleshooting to lead you in the right direction. It would also be helpful if you could provide us with some more context about your particular situation. What platform are you using? What is your topology like? Are you implementing any QoS, traffic shaping, policing, or route maps or policies? All of this information, beyond simply sharing the error counters, will help us help you better.
Let us know how you get along.
I hope this has been helpful!
