I need to run an utilization and netflow traffic report on one interface only.
The reason for this that we are going to move a group of people off campus to another site and the powers to be want to now what size pipe to give them. The netflow part comes in because the building that houses the people does not have the file servers that are going with them. You gotta love upper management.
Couple of ways depending on what exactly you need to achieve.
If I got what you need correctly you can just open the report in report writer, on Filter Results tab add a condition to specify the interface (eg. using the Interface ID) and save the report (as a new one, so you don't overwrite the general one). You can run it in the Report writer or view on the Web.
This modified report should only include the filtered data.
