3239.0. "Ethernet AM and DOS(TCP/IP) problem!!!" by ZPOVC::RAMARAJ () Wed Jun 24 1992 06:05

    Is there something different in Pathwork for DOS(TCP/IP)?
    
    The Ethernet AM can never register a PC running TCP/IP!!!.
    I tried it on the latest DOS(TCP/IP) V2.0 and still have the problem.
    
    With DECnet on the PC, and using the aa-00-04-00-xx-xx address, its ok.
    
    Has anyone succesfully registered a PC running our Pathworks TCPIP s/w.

3239.1Ethernet physical address is differentCUJO::HILLDan Hill-Net.Mgt.-Customer ResidentThu Jun 25 1992 02:4324
    Try using the original Ethernet physical address for the controller.
    
    If it is a DEC controller, then the address will look like this:
    08-00-2B-xx-xx-xx.  This is the address the controller broadcasts
    before you start up DECnet Phase IV.
     
    FYI:
    As soon as you start up DECnet Phase IV, a new address based on the
    DECnet address (say 3.8) is calculated thusly:
    
    3*1024+8=3080  
    3080, converted to hex is 0C-08.
    
    Swapping the hex pairs, then adding the normal DECnet prefix
    results in AA-00-04-00-08-0C.  This becomes the new physical 
    address for the node.  
    
    Any time you start DECnet first, this is what happens.  If TCP/IP
    is started before DECnet, you should see only 08-00-2B-xx-xx-xx.
    
    By the way, Phase V DECnet will not change the physical address
    any longer.
