ACL with Inter Vlan

We are used Cisco 3750 Layer 3 Switch and linksys switch at Layer 2 level.

We are used total 10 VLAN,  We want block all inter-vlan communication,  So no body can access inter vlan .

All vlan can access server vlan

 

 

Thanks

Based on what you have told us one solution would be to configure an access list for each of the SVIs on your 3750 switch and apply it on the inbound direction for the interface. In the access list you would permit packets with source address in the vlan of that interface a destination of the server vlan. You would deny all other traffic. This would allow each vlan to communicate with the server vlan but not with any other vlan.

Just put access-list on 3750
