1838.0. "Support Specialist" by NETRIX::"[email protected]" (Nancy Flavell) Wed Oct 18 1995 17:29

Am I in the correct place for asking about the following on a DEC 7000 with DEFPA 
controller?  The problem manifests itself as very slow nfs communications across
the fddi.  We also see in the kernel log file:

fta0: Ring initialized    (repeated for pages and pages)
fta0: MAC CRC Error        (repeated several times)
fta0: Duplicate token found

From uerf:

DEC OSF/1 V3.2B  (Rev. 214.61)
fta0: DEC DEFPA (PDQ) FDDI Interface
fta0: Firmware rev: 2.46

The customer says there are no nodes being added/removed from the ring.

Do I ask here correctly?  Any assistance would be appreciated.

    	FCS failure and Reinitialization received (ring init by this link)
    suggest that you have a hardware fialure, probably cabling or
    Concentrator if present.Or the controller itself.

Thank you for your analysis.  I will have the hardware checked at that site.
