mac access-list problems

Unanswered Question
May 5th, 2009

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?

I have this problem too.

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