Tassos, Can you send me the list if SRs? ME3800X should not be dropping packets with maximum queue-limit. We are working on an enhancement to increase the queue-limit range. Is there a SR for the counter issue? Can you also send me the details of the last issue "matching of non default classes"? I would like to do further investigation on that topic. I would recommend moving to 15.1(2)EY1 once it'll be available on CCO in couple of weeks.

I know about bursts and so on, but the same traffic wasn't causing any drops on the older platform. We tried some output shaping service policies under the interface, but the drops were still there, and then on the policy-map too. We also noticed that the rate counters on the policy-map were totally wrong. Then we applied shaping service policies under the service instances and increased the queue-limit to the max available, and the drops got very low (but still existent). Tac concluded that this is due to the default egress buffers being too small, and we're waiting for the developers to come up with a solution. Another issue we met, is that any match of non-default classes under the service policies under the service instances wasn't working at all, when there was no ingress L2 control traffic from the other side. I know it sounds very strange, but this was the conclusion we came to, after doing many different tests. To summarize, we have quite a few of strange cases with tac on this platform. -- Tassos Nick Hilliard wrote on 22/11/2011 22:29: > On 22/11/2011 18:44, Tassos Chatzithomaoglou wrote: >> Unfortunately there are still a lot of features missing + some things that >> don't work well (primarily the -hardcoded- small egress buffers) > Can you elaborate on this? > > Nick > _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
