3971.0. "datalink xmit error on set host/mop" by GADWAL::W_MCGAW () Fri May 23 1997 16:33

Hi,

I am working with a customer that is having problems with MOP on a VMS 
V7.1/OSI V7.1 node.  

We booted up the system after switching from a DE435 to a DE500-XA and the 
system came up correctly.  DECnet/OSI and LAT connections worked correctly 
but any set host/mop commands we try result in a Datalink Transmit Error.

The mop circuit (csmacd-0) is using the correct data link of csma-cd 
station csmacd-0 and the correct Communication Port is being mapped from 
the station entity.

A loop command from a terminal server hardware address or a Phase IV 
physical address fails with the same datalink transmit error too.  Running 
a trace while trying the set host/mop only gave a single entry in the trace 
which was a:

-----------+----+-----+-------+-------------------------------------------------
    Time   |Evnt|Data |MOP    |Data                                             
hh mm ss cc|    |Size |MsgType|                                                 
-----------+----+-----+-------+-------------------------------------------------
12:16:16.82|  Tx|    4|RqID   | 00 02 00

Each time we try the sethost/mop, the data field increments by one.

Does anyone have any ideas on what to look for?

Can anyone offer help with the problem in the base note?  This is related to an
IPMT case being worked on by the Printer Engineering group.
