I got a 3550 SMI Multilayer switch and 2950T series switch.I have done configure both of the switch as Inter-Vlan Routing.The result was successfull.My question was is it posible to block Vlan so that it cannot access other vlan eg:(ping,network neighbourhood,telnet,etc).FYI,the Vlans is different subnet mask.If there any solution to do a network security?Can you provide examples of configuration or URL address so that i can refer.

Can you please explain in detail about ACLs procedure and how to configured.

Thank you.
