Largest ACL on ASA 5510

Hi,

What is the largest ACL (actually object group of networks) I can use on a 5510?

I'm blocking traffic to/from certain countries. I have one that is about 4,000 lines long that works fine but would like to add others and not sure what the upper limit is.

Any guidance from Cisco?

Thanks.

Hello Lcaruso,

As far as I know there is no top limit, I mean certainly there should be a boundary but I have not seen it before so you should be good ( On the FWSM we do have limits, on the ASA as long as your memory supports it we are good )
