870.0. "NDU errors on remote DEMFA" by BRAT::BUKOWSKI () Mon Feb 22 1993 20:45

    I am not able to find the firmware version of my DEMFA's.  I have
    NDU installed on a 6420 with only one Network interconnect, and I 
    am issuing the following command:
    
    $ Download show dev 08-00-2B-27-DA-45
                             ^
                             |
                       Ethernet Address of the remote DEMFA
    
    
    This results in a NDU read error and a device timeout error.  What
    is wrong?  How else can I obtain this information.  Also, If I can
    not read the devices remotely, how am I supposed to upgrade them?
    
    Any help appreciated!
    Thanks,
    Mike

down show dev fxa0:

I think that's right.  You can't see the firmware revision of remote DEMFAs
using NDU.  (Though if you can trace the MOP SYSID packets, the firmware
revision is included at parameter 101)

870.2only good for RBMSQUIVER::PARISEAULuc PariseauTue Feb 23 1993 09:465
	The 'show dev' command in NDU issues an RBMS request frame to the
	device.  If the product doesn't speak RBMS, the request will timeout.

    Oh ya.  I saw the Note: within the VMS help that mentioned the FDDI
    controller 400 wouldn't respond, becuase it didn't use RBMS, but I
    didn't know that the 400 was actually a DEMFA, untill I did a "download
    list".
    
    Ok. What about the firware upgrade?  How will I be able to do the
    upgrades?   Will I be forced to install NDU on every system with a
    DEMFA?
    
    Another question:  From what I hear DECndu will soon be unsupported as
    we move to a replacement application.  What is this replacement called,
    when will it be available, and what will it require.  Oh, and will 
    remote upgrades work from source nodes using FDDI controllers as
    Network Interfaces?
    
    Thanks,
