Question regarding Vlan maps on 3550

Hi Group-

I could use some clarification on the overall functionality of vlan
access-maps and filters. I have two routers r4 and r5 on vlan 54 connected
through the 3550 with no SVI. I would like to configure it so only R4 has
access to vlan 54. I am not concerned with port level security, I would like
to do this with the vlan access-map and have had no luck. I looked at a
couple diff examples (3550 config guide 18-32) and it doesnt work for me. I
have a config below. I am unable to get what I would expect to be the right
result. I would think the config below would allow the mac defined and deny
all other traffic through the switch on the vlan. Thanks in advance for your
assistance!
