Global attachment point 2. icmp-off 3. acl-aggregate-interface stats. For (1), my first preference is to have the model define attachment point for interfaces only. einarnn> I have some diffs, layered on top of Mahesh’s PR to netmod-wg/acl-model that do this. Nearly like the augmentation I have below. Feel free to take a look at: https://github.com/mjethanandani/acl-model/pull/3 However, Kristian wants the global attachment point as well so that he can add the ACL to the linux tables. einarnn> I think Kristian doesn’t feel a global attachment point needs to be in this first revision. But he can confirm. If an ACL is attached globally, does this mean it is per direction or does it mean it is across directions? einarnn> I don’t know right now :-) This global ACL may not be applicable to any of Cisco's service provider routers as I don't see any platform actually replicating the ACL to all line cards and attaching it in ingress and egress directions across all interfaces. einarnn> Per other emails, I don’t think we understand this enough yet to specify it, so I suggest we just leave it out for now. Nothing in the model prevents a “global attachment point” being added later once we understand what it really means. For (2), I am ok with removing icmp-off. einarnn> Done in my PR above. For (3), this would have to be a combination of ACL stats across all interfaces for all ACL's. Something like this is possible on an XR box where ACES have counter names associated with it. Let's chat about this offline tomorrow. einarnn> I’ll ping you to clarify, and we can bring any conclusion back to the list. Cheers, Einar Sonal.

Down the line we might need to have an container for "attachment points" to accommodate the possibility of attaching an ACL either to an interface or “globally”. Keeping in mind that one use is that an ACL doesn't attach to an interface at all. _______________________________________________ netmod mailing list netmod@ietf.org<mailto:netmod@ietf.org> https://www.ietf.org/mailman/listinfo/netmod Mahesh Jethanandani mjethanandani@gmail.com<mailto:mjethanandani@gmail.com> _______________________________________________ netmod mailing list netmod@ietf.org<mailto:netmod@ietf.org> https://www.ietf.org/mailman/listinfo/netmod
