Good Morning ...
Hi friends I have a pendent for solving request at my job, let me explain you:
1) I have switch Catalyst 2924 XL-EN, it has 24 ethernet ports(Fa0/x), 4 Fiber Optic ports(Fa1/x), and 1 ATM module(Fa2).
2) every ethernet port has a hub attached to it.
3) every hub has at least 6 PCs attached to it.
4) One of FiberOptic port is connect to communications office, where proxy-internet server is installed.
5) Not all PCs must get into internet, just authorized PCs, but proxy is open so we try to control access to that proxy-server using switch.
Does anybaody could help me to set up tjhat block process on switch ?
