Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Ok, success! Well, it turns out, we had a bad CSU. Strange thing, though. It worked ok on the 3Com equipment and last time we did testing, we put the CSU on the Cisco and it didn't work. We put it back on the 3Com and it worked fine. This time, we couldn't get it to work on the Cisco, tried putting it back and it died. We configured (yet) another CSU and up it came. I guess you can never try enough hardware sometimes. Thanks for all the input. It's much appreciated.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
You are correct, the LMI is set at the interface level.
One command that I don't think has been mentioned is 'debug frame-relay
lmi'. It's pretty safe for a debug command - it shows you what is
happening between your router and the frame switch. You should see status
enquiries and status messages every 10 seconds, and every 60 seconds a
list of PVCs known by the switch, and their status. The 10 sec/60sec
might vary depending on switch type - I'm not sure.

Thanks everyone for all the input... We're doing another test today at 4pm
(EST) so I'll get more info and I'll try using different lmi-types. I
seem
to remember trying ansi, but I'll give it another go and I'll document all
of the show frame map/pvc/etc in case it doesn't work again. Am I correct
in assuming that the LMI is set only at the interface level and the
subinterfaces will get it from the interface?

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Well, the sub-interfaces do not need the LMI, it is only used to report the information about the dlci's to the interfaceactually I have turned off the keepalives in a lab environment and still pass traffic to a frame switch.keepalives =LMI for CiscoThe other thing is to be sure of the type of FrameRelay encapsulationCisco or RFC1490Cisco routers default to CiscoThis is set at the dlci level Terry Vore At 02:59 PM 1/17/2002 -0500, you wrote: >Thanks everyone for all the input...

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Yes, the LMI is set at the interface level. However, since you're using 12.0 the router should auto-detect the LMI type.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Are you positive you have the DLCI assignments the same as in the 3COM router you replaced? What do 'show frame map' and 'show frame pvc' look like? Do you have any PVCs that are UNUSED/INACTIVE? On the remote side that is UP/DOWN, do you see any incoming packets at all or does it think the interface is up simply because DTR is high? What does show interface show on the remote side? Equal numbers of LMI enquiries sent compared to stats received? Thanks, John >>> "Bob Timmons" 1/17/02 10:35:42 AM >>> On S5/1 I get UP/UP.
