Our router is receiving ignored errors on one of its interfaces. I have done a little research and found something on rx-ring limit being the possible cause. Can someone please help me with a command to raise this limit. It is currently set to 64 and the router is a 2851. Thanks in advance.

This generally indicates you're oversubscribing your router. Check 'show proc cpu history' and see if you have periods of CPU at 100%. If so, you either want to disable some features (QoS, NAT, Firewall, VPN) or upgrade to a 3800.

CPU is fine. Runs at 4% and never peaks above 12%. Is there a way to increase the rx-ring?

I worked with TAC and found out that there is a bug in the code and we needed to upgrade so the rx-ring was 128 instead of 64. You can not change it through software.
