How can I fix overrun errors on an interface? I have 6 serial interfaces and all of them have CRC errors, frame errors, and overruns.
Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.
It sounds like queueing could help, but I can't put fair-queue on these interfaces. I could rate limit, but I'm not sure that would help. Should I shape all of my traffic out to my link speed, and am I even on the right track???
Ok, Google came to the rescue:
Q. How do you position the Cisco 2800 and 3800 integrated services router WAN optimization bundles in the branch office?
A. The Cisco 2800 integrated services router WAN optimization bundles should be positioned at medium-sized and larger branch offices of 20 to 50 end users with bandwidth requirements up to 4 Mbps (2 T1/E1). The Cisco 3800 integrated services router WAN optimization bundles should be positioned at large branch offices and small regional aggregation sites with 50 to 150 end users and bandwidth requirements up to 16 Mbps (8 T1/E1).
