inter-vlan routing

I have three vlans on a 3750: 50, 51, and 52. I currently have ip routing enabled and all traffic is routing between the three vlans okay, but now I want to limit traffic to vlan 50 (use 50 as the management vlan and 51 and 52 for access vlans). do i just do this with an access-list that denies traffic from one vlan's subnet to another, or is there a way to specify ACLs directly so the filtering is at layer 2? can someone give me an example or some reference documentation?

thanks.

Re: inter-vlan routing

Hi Matt,

ACLs are definetely traditional and easy method to achive what you are looking for.

There are MAC ACLs available on 3750 switch but they are only used for non-IPv4 traffic on a VLAN.

On the other hand you can also look for Vlan MAPs

Have a look at this link
