Frame-relay switch (2610 with NM-8A/S)

Unanswered Question
Jul 2nd, 2009

I recently bought a FR switch on eBay however when I connect it with another router's WIC-1T interface both ports show "down/down"... I tried different clock rates, sync/async modes and different encapsulations but no help. The cable I use is normal DCE-DTE cable. The cable works fine when I connect two WIC-1T cards together. The FR switch does show me 8 Serial interfaces in show run... Any ideas? Thanks!

I have this problem too.

I believe that the NM-8A/S defaults to async operation and the WIC-1T is sync. First I would make sure that the NM-8A/S is really set to operate in sync mode. And I believe that in sync mode the card is limited in the speed that it can support. So I would configure a very low clock rate.
