RE: keepalive set in frame-relay circuit?
I'm not sure what setting the frame-relay keepalive to 0 would do. If your router wasn't receiving LMI to begin with than you are probably getting a false line protocol up reading. LMI is needed so that the frame-switch can tell the router the status of the pvc's and dlci's on that circuit. If the switch and router aren't talking then the router probably doesn't know about the PVCs it has to get to remote locations... Hope I didn't get off track I just skimmed your question.

RE: keepalive set in frame-relay circuit?
thank you very much your explanation is crystal clear -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, October 10, 2000 1:50 PM To: [EMAIL PROTECTED] Subject: RE: keepalive set in frame-relay circuit? 10 seconds is the default, and should generally be fine. Your circuit is probably down for some other reason. Is this a test setup, with the routers connected back-to back (or with another cisco as a switch), or is the frame relay circuit a 'real' circuit from a telco? Assuming it's a real circuit, try the 'show frame lmi' command. Your 'num status enq. sent' and 'num status msgs recv' values should be the same (or very similar), and non-zero. If they aren't the same, clear the counters, wait a minute or so, and check again. If you are not receiving any LMI messages, then you're not talking to the frame relay switch. This is not a good thing. Either your router config is wrong (wrong encapsulation? wrong lmi type? could be a few things) or the telco service is broken (or dud hardware, potentially). If the LMI looks OK, try the command 'show frame pvc', or turn on term mon and do a 'debug frame lmi' (it's a fairly safe debug to do even in a production environment, unless your routers are very overloaded or you have zillions of PVCs. But I take no responsibility if it breaks your network :-). See what PVCs are defined, and which ones the telco knows about. See if they match what you think they should be. With the debug frame lmi command, you will see (hopefully) LMI messages coming from the switch. Check that they're coming in every ten seconds. If not, change your keepalive to match. Every now and again (every minute on mine, YMMV) the LMI message will include the status of all the PVCs the switch knows about, and their status (I believe the exact format of the messages varies between frame switch types. On mine, an active PVC has status 0x2, and an inactive one has status 0x0). Even if you force the interface up/up by fiddling with the keepalives, it won't pass any data if the circuit's broken.

No keepalive is a means of forcing an interface into an up-up state from the router's viewpoint even if the interface may in fact be disconnected.

You may be able to make it work in a lab situation with no keepalive on a router configured as a frame switch, but it isn't a good idea.
