We already monitor traffic usage on the switches with cacti via SNMP.
But, I need to block traffic abusers automatically. from any IP
address, to any IP address.
The firewalls we have, and have tested all need a set of IP addresses
to throttle, which won't work in this case.
A user can login from any IP address on the internet, and either
upload or download exsesively and we need to block that IP address as
soon as it's reaches a certain (pre-set by us) threshold
