Re: [c-nsp] Too dumb for SLB on ASR1Ks?
So far, I have gotten only the one response to my question. What would be the suggestion? Ask Cisco for configuration help? Create a bug id? Any ideas/guidance? I'm under the impression my basic config should be working but it doesn't... You know, any input etc...

(Although it could take weeks like the time I threw an IPv6 question at TAC.) If it is supported and it's broken, they should be able to open a bug. I'd help more since I use IOS SLB a lot, but I just don't have an ASR1000 as much as I wish I did. ;) ~Seth ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

I just asked one of the platform PM's. It's not supported on ASR1k. Rodney On Tue, Apr 07, 2009 at 06:01:15PM +0200, Elmar K. Bins wrote: So far, I have gotten only the one response to my question.

This is the lab setup; you can count on routing being alright - connectivity among all parts of the setup is working, and I reconfigured the servers myself (UNIX guys usually get netmasks etc. wrong *g*). You can also see this from the drop-in replacement (7201) working perfectly in the setup. The point is that the ASR receives the packets but doesn't push them on. They do not appear in any statistics (SLB or port) and they do not appear on the wire or on the target server. There are two things that would help my cause, one being an idea whether someone else successfully or unsuccessfully used SLB on ASRs (or the info about serious trouble there). Then I'd like to compare configs; maybe I forgot some magic word. There is no documentation for SLB on IOS XE to be found, so I'd be happy about pointers towards recipes or HowTos, since 7*** configs don't seem to work - provided it's not some crazy bug that keeps the ASR from pushing the packets on.
