1043.0. "Some questions about download hubs" by ALCALA::SOENGAS () Tue May 31 1994 04:31

    
    
    	Hi,
    
    	I am beginning to work with hubs and I have some basical questions:
    
    	VMS 5.5-2, UCX 3.1 ,Hubwatch 3.0
    
    	I have 5 hub900 multiswitch.
    
    	The first hub have one ip services module (deconcentrator 900mx)
    	The another hubs only have repearter 90c and repeaters 90fa and one
    	dec agent 90.
    
    	I install nduplus 1.0, and DCF010 all ok.
        The hubs have firmware versions old and there are modules on the
    	hubs that too have firmware old and I try to download the
    	new versions.
    
    	Questions???
    
    	1. If I need to download firmware sofware to the hub, I have
    	   configure bootp and tftp from UCX.  Then what is the
    	   use of SYS$COMMON:[SYSEXE]NDU$TFTP.EXE;1
    
    	2. If I need to configure bootp then how yo may obtain the hardware
    	   addres for the hub???
    
    	   ucx> set bootp 1.0.2.3/file=tftp_root:fichero.bin/hardware=??????
                            !
                            !
    			ip addres of hub 
    
    	3. On the hubs that don't have ip services module, that have
           decagent90.
    
    	  1. I configure from setup on the hub with a terminal the ip address
    	   and the community name(ip address 7.0.254.251,community name
    	   public).
    
    	   But when I try from host ucx> ping 7.0.254.251
                                              ip addres of hub
    	  
    					was unreachable
    	
    	   Yes, I understand that in this hub of this manner there are not
    	   any element that answer to ping(there are not ip services
    	   module).
    
    	   I prove the following after this:
    
    	      I put the Decagent 90 on module 6 of the hub
              and configure the Decagent 90 with Ip address 7.0.254.250
              and community public.
              I configure from setup on the hub with a terminal the ip
   	      addres and the community name(ip address 7.0.254.251,community 
              name public) and say that ip service module is in slot 6.
    	      All in band information oh course.
    	      
    	      The question is:
    
    	      It's possible download firmware revisions of hubs that only
    	      have decagent 90 and no ip services module.  If yes what
    	      are the steps in order to make this.
    
    
    					Best Regards,

I'll take a stab at these:

This file is the TFTP loader for DECndu.  If you invoke the VMS DOWNLOAD command
to load a device via its IP address, this is the image that runs to do the load.
According to our DECndu guru, you must disable any TFTP servers on your load
host before invoking DECndu.  If you do not, DECndu will get a bind error when
attempting to make the connection to the device and will exit.  However, the UCX
server may serve the requested file to the device anyway.  Unfortunately, all
the fancy block count and load in progress indicators are part of the
NDU$TFTP.EXE image, which will not be running due to the above bind error. 
Bottom line, don't configure UCX to be a TFTP server if you are loading via
DECndu.  This is all spelled out in the DECndu release notes.

You can't.  The hub does not have a hardware (MAC) address.

The DECagent 90 cannot be configured as an IP services module for the DEChub
900MS.

Yes, this is possible, but not trivial.  It requires that you setup both the hub
manager out-of-band serial interface and an external terminal server port (90TL
or 90M) as a SLIP port.  I am not familiar with all the details of setting up
the terminal server.  Maybe someone else can provide additional information.

Hope this was of some use.
