Wouldn't you just do that in your reporting? The report engine
usually has options for interface, ingress/egress, prefix range,
protocol, ....<br>
<br>
Then when you need to aggregate for a specific interface for
additional troubleshooting, you have all the information for when
you need it.<br>
<br>
Yes, your aggregate numbers for total packets transiting is double,
but I generally have specific reports for specific traffic patterns
I focus on anyway.<br>
