mac access-list problems

I have a Cisco 3550 installed. I'm using IP and MAC access-lists. The IP Access-lists are working like they should. However the MAC Access-list seams to have issues with applications.

The mac access-list are setup to allow traffic from a couple of MAC Addresses to a single MAC Address. The mac access-list is then added to the FastEthernet interface.

Pings and normal file access don't seem to have issues with the mac access-list, however any program that pulls data from the server across that mac access-list will time out after about 10 minutes of sitting ilde. I've changed the mac-access-list aging-time to 0 to disable it. However the problems still persist.

Can anyone shed some light on why this is happening?

disappointing...ask this question on many bbs, nobody help,cisco neither.

If you remove the ACL does the problem persist? Meaning, are you sure the ACL is the root cause?

Thanks, James.

Sure, no such problem before adding the ACL. after removed the ACL, then the problem disappear.

the ACL is following as below,

mac access-list extended HR

permit host 0000.0000.0001 host 0000.0000.0001

permit host 0000.0000.0001 host 0000.0000.0002

fa 0/22:mac access-group hr in

Sorry, the ACL is,

permit host 0000.0000.0001 host 0000.0000.0002

permit host 0000.0000.0001 host 0000.0000.0003

fa 0/22:mac access-group hr in
