[mrtg] Cisco VLANS on RSM or MSFC rates

Okay - We've all figured out that you can't get VLAN traffic rates out of an 
RSM by using the interface number of the VLAN as it only reports the first 
packet in a flow...

That being the case, can we use this to accurately and TRULLY report the 
number of 'Sessions' per second?
Do the counters on 'IN' reflect the number of 'internal' to-the-vlan 
sessions? [end  points inside]
Do the counters on 'OUT' reflect the number of 'external' to-the-vlan 
sessions? [an endpoint outside]
Can anybody from Cisco comment?

If we can agree on what the VLAN ifIndex actually counts, and if we can 
agree on how to label the graph, then we would have a pretty solid metric as 
to how to rate my VLAN against yours, que no?

I think this thread has merit and has the potential to define a new way of 
measuring our loads & traffic...
