I think this switch only sends data through on the network. In order to stop certain ports or internet websites you would need to do this on the router itself. If you have a cisco router then yes you can block certain ports and internet websites but you would have to mess with the configuration file on the router. This usually means connecting the router to a laptop with the appropriate connector and then you will need the admin user id and password to access the configuration file.
Hope that helps.
no not at the switch, you can at the router or firewall if you have one
With that model switch you will not be able to do any of those functions. If you have a cisco firewall (Cisco PIX or ASA) you can use Websense on that. You can also use the Catalyst 6500 Switch or 800 series routers with the correct IOS. They all have the correct software functionality to look at the packets in the application layer.
A cisco switch or any switch for that matter is a layer 2 device, ie. it only understands MAC addresses, i.e. physical addresses of the NIC’s connected to its (the switch), port.
when you talk web access or any tcp/ip based service, you are talking layer 3, this is a job only for routers.
so you will have to implement the solution to your problem at the internet connection source ie. your router or such device given to you by your ISP.
again if you have a small no. of pcs, and you do not have any type of server, you can block what you do not want at each pc level or user level. This can be a pain because the more the no. of pcs, the more errors can be introduced into your security soluiton.
My advice would be if you want to control cost, and do not want to invest. You can use some old hardware thats around and make a cheap router with FREESCO.
very effecting in controlling browsing and implemetation is fast.
