Re: Switch Connection Limits/Throttling

I didn't say "authentication attempts", I said "connection attempts".

For example if a piece of malware got on a system and started to run port scans or spew spam out (can't block 25). I worked at a facility once where the network team rolled out an edge NAC solution (Cisco switches/Cisco Clean Access) that would disable the port if X number of connection attempts occurred over a certain period of time. Workstations seemed to be ok, but if you tried to run a server or run NMAP over a workstation attached to such switch, it would knock the port off.

I've since moved to another company and it might be usable here, but I'm not sure how they did it.

Thanks!
