Hi every body,

I have a high speed internet connection which is distributed to four users of the IT department, as all of us are from IT department I can't force them to have a connection from ISA, they r connected directly from the 3550 series switch with real ips, some of them are using software?s like kaaza, bit torrent, bear share for their downloads which is consuming more bandwidth which limits the browsing and download speed, I did tried to limit their bandwidth from their respective interfaces with following command
Interface fast Ethernet 0/1
Bandwidth 1

But no use is there any ways to block those software?s and to limit the bandwidth usage for individual user, as I can use any bandwidth limiting software?s. The only option I have to control them from the switch. So please let me know the solution.

Thanks

Yasir

Why dont you look at the ports that the programs are using (bearshare, bit torrent, ect.) and block the connectivity by port through the switch, if they can't connect they can't use bandwidth!. Another solution could be to put a firewall on the machines (since there are only 4) and block these programs from running and there respective ports locally. Then at that point put a password on the firewall that they can't figure out and problem solved. You can also limit the amount of bandwidth these programs use from within there options.
