If you have been struggling with this as well, I'm eager to hear about it off-list.In 12.0.15S you cannot use access-lists on subinterface on the 3GE either. Wonder if that's a software bug too, or hardware limitation (like the MTU difference on the 3GE compared to the 1GE).
Actually Cisco has never supported ACLs on Engine 0 or Engine 1 cards in the GSR. Used to be that you could apply those ACLs, but they were implemented by the router very erratically. Cisco finally removed the ability to apply ACLs to an ineligible interface because the TAC was tired of telling people "it's not supported, even though it's there." Best wait another 6 months for the Engine 2 10xGIGE card which will support ACLs, or change to/add something from the 7xxx platform. DownReving the router isn't really an option, like I said because the ACLs never really worked right anyway. I don't remember the exact details (I can get them if anyone wants) but I believe it did something like arbitrarily testing random packets with random rules, whereas some packets would get thru without being checked at all. -- =-=andrewo
