Re: Standards for IP stats collection? (corrected)

["terry martin" <tmartin@gvnw.com>]

RMON is the only protocol standard that dictates information collection
requirements.  That is the only IP service that is structured to collect
trend stats.  I think it is also 15 minute intervals for 3-5 days depending
on how much memory you get in the unit.

There are structure requirements for collection, type of traffic collected
and how it is presented.

Need sources- let me know
