How to prevent vlans from communicating with one another

Ok here is the scoop. I have a catalyst 6509 and prob about 20 vlans created on my 10.5.x.x network I would like to prevent all the other vlans to access vlan 101 --- however i still need to be able to get out to the internet--- all of my catalyst 2950's come into this one 6509. I would also like to limit only one certain mac address on a port on a 2950 I do not know how to do this either... Any advice would be greatly appreciated.

Re: How to prevent vlans from communicating with one another

I'm not sure if you are running hybrid or native code on the 6500. I think want you are looking for is a feature called private vlans

For the 2950 I think you are looking for port security, http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/12119ea1/2950scg/swtrafc.htm#1038501
