cisco 2621 T1 dlci problem....

[markm123]

I am starting a small isp and I currently have a cisco 2621 with a wic-1dsu-t1 card in it, I just got the card today and I have been using a netopia R5300 that my provider let me borrow until the wic came in. Heres my problem, on the R5300 everything works great, on the cisco no matter what frame-relay setup I use the DLCI will not come active, the debug for the lmi shows lmi traffic but shows the DLCI status as 0x0, everything I read on this shows its on the providers end, but when i plug the netopia back in everything works again. I have tried Interface only, sub-int, inverse-arp and maping configs from several pages of cisco docs (Im officially cross-eyed). if anyone has any suggestions please Help, Im at a loss now.

Thanks,
Mark Maimbourg

If you type show frame-relay pvc does it show the PVC status as Active, Inactive or Deleted?

 

[markm123]

shows it as inactive, is it possible that I have a bad wic?

 

[techkiwi]

A couple of pointers (and bear in mind I'm no expert, so may have missed something really obvious!).

If the PVC is showing as Inactive this indicates that your connection to the Frame-Relay switch is working but you're not talking through to the router at the other end. Has the telco changed something?

What type of router is at the other end? Maybe it is using Cisco encapsulation so you could try encapsulation frame-relay cisco.

From Release 11.2 onwards, Cisco routers can autosense which LMI type the FR switch is using, so maybe to eliminate this as a possibility remove the frame-relay lmi-type ansi command. But as your PVC is Inactive this would seem to be unnecessary (if it showed as Deleted then you would suspect some error between your router and the FR switch). If you do suspect a problem here, type the command show frame-relay lmi and take note of the status messages sent and received. Wait about 20 seconds and then try again. The status messages sent and received should increment by 1 every 10 seconds.

I'm not familiar with the 2621 or the wic-1dsu-t1. But looking at your config you seem to have the controller installed in slot 1/0, yet you're configuring serial 0/0. Can you clarify what slot you are using and the physical type of interface (a T1 controller or a serial interface)?

Like I say I'm no expert. But maybe there's somebody else out there who can add to what I've said.

Sorry, as far as the t1 controller goes that is a pri module that im currently not using. As far as the encapsulation my isp assures me its ansi. As far as the lmi stats, they are working correctly thats why im so puzzled, the vendor i purchased the wic from is overnighting me another one so I can see if its a bad Wic..

Thanks for your response I will let you know how it goes..
