Is anyone running a 3620 router, with an NM-2FE2W carrier module, with a WIC-2T using Frame-Relay?
I have been asked to look at a possible hardware issue with these components, and have seen one of the serial ports up, and the other bouncing.
The circuits have been tested and are fine.
I have put the router in a lab using HDLC encapsulation, and can get both serial ports to work. I have even put a WIC-1T in the spare slot to ensure that the WIC-2T is not faulty. All three interfaces work.
When I configure the router for Frame-Relay encapsulation, the WIC-1T interface is fine and traffic passes over the link.
The WIC-2T interface comes up when enabled, but drops after 30 seconds (3 keepalives).
By debugging the Frame-Relay LMI I see that the router is not receiving LMI status messages from the FR switch. The FR switch (another 3620) is sending the messages, and is receiving enquiries from the DTE.
eg (taken before the DTE drops the link)
00:16:14: Serial0/0(out): StEnq, myseq 3, yourseen 0, DTE up
From the description you have given this is NOT a hardware issue.
Try dropping the clockrate on the dce to 64k for a test, I know it should support higher speeds but I suspect this is part of the problem if it work we can then work out why the higher speeds didnt work
In the 2nd NM wic slot do you have any WIC's installed ??
