ISR G2 ACL support

[sshanahan]

Can anyone tell me how many ACLs are supported on the ISR G2 platform? I spent a decent amount of time looking through data sheets, licensing documents, white papers, and configuration guides and I was hoping to find documentation that outlines how many ACL entries each series of ISR G2 supports.

Your help is appreciated!

I think that number depends on many factors, memory for example..

The rule is:

One ACL per protocol

One ACL per interface

One ACL per direction(in or out)

For example on one router with 3 interfaces with 2 protocols running you can have 12 ACLs applied

Hope this helps

I understand that. That's not really what I am looking for.  For example, an ASR with an ESP-20 supports up to 16,000 unique ACLs, I know that the Sup2T on the 6500 supports a max of 64K ACLs.  I was hoping for a more specific number that would outline the maximum supported ACLs for the ISR G2s.

Do you have access to the router?

Maybe you can check the memory allocated to process and get a rough ideea

I had a look at 3725 with 12.4 and had allocated to Extended (i didnt see a entry for standard, i guess is part of same process) ACLs process the value of 65355 bytes (close to 64kb). show memory allocation-process totals could help you.
