If a question asks to generate an RMON alert when the number of input
errors on an interface exceeds 50 per second, should you use absolute
or delta? This sounds like an absolute event, rather than a delta
event.

If it asked you to alert when the input errors *increased* by 50 per
second I would have thought this was a delta event. However, I'm being
told differently...

Can anyone explain how you can differentiate between them?

Thanks
Roy
