Is there a way to deny large file transfers?

[corpengineer818]

Is there a way to deny large file transfers for common TCP protocols (SMB, NFS, FTP, SMTP, RDP)?  Say for files of size 10MB, or 100MB?

I know this is a very general question, but is there a way to stop file transfers once a certain threshold is hit?  I have configured traffic policing, but I am getting very inconsistent results using:

police output 8000 conform-action transmit exceed-action drop.  

Sometimes it seems to work, but usually it blocks everything, or nothing (using 8000 or 9000).

Thank you.

I don't believe you'll be able to configure the firewall to allow files of small sizes and not large across all those protocols.
