Drop percentage?

JayrodEF

Hey all,
General question, on an interface, how to calculate the percentage of drops vs. traffic? For example, an interface shows:

91100226 packets output, 54264321771 bytes, 0 underruns
27539837 output errors, 0 collisions, 0 interface resets


Is the percentage of output errors the (output errors/packets output)*100 or (output errors/bytes)*100?

Thanks!

Your interface output 91100226 packets. You had 27539837 output errors. So as a % of total packets, that's (27539837/91100226) * 100 = 30.23% error rate.
