Stop Downloads use L3 Switch

Hi All,

I have configured multiple VlANs (Vlan10 and 20) on cisco L3 switch. And I want to stop downloads to Vlan20 users on L3 switch. Can I do this on my cisco L3 switch?

Please respond..

Regards,

Satish.

Satish,

What downloads you want to stop? I believe you can do that on the firewall not on the switch.

If the downloads you said is like: user can open http://software.opensuse.org/123/en but will be blocked if user try to download the ISO image from the site, then i don't think 2900 router will do any help on this. what you need for this is a web filtering software or device or proxy server that support filtering (like ISA server, websense).

Hi,

If you want to block file sharing from the VLAN , use the extended inbound & outbound ACL blocking TCP port 445,135,139

ip access-list extended Deny-fileshare

deny tcp any any eq 445

deny tcp any any eq 139

deny tcp any any eq 135

permit ip any any

int vlan 20

ip access-group Deny-fileshare in

ip access-group Deny-fileshare out

It will block all filesharing communication from VLan 20.You can apply ACL on router also , the LAN port which goes to your CORE Switch.

Thanks
