432.0. "Online documentation for DEFEB, DEFCN?" by BSS::C_OUIMETTE (Holographic Interference Repository) Wed Dec 18 1991 19:42

    	Hello all,
    
        Now that SNMP is supported on the DEFEB/DEFCN boxes, is there any
    documentation online (updated user's guide, problem solving, technical
    guide) which describes configuring the new boxesfor IP? Specifically, the 
    use of BOOTP with DB6xx's? V1.1 f/w release notes, maybe? All pointers
    appreciated.
    
    						Thanks,

    The Release notes contain documentation on setting up the boxes.
    All you really need to do is assign it an IP address via Bootp
    or ELMS.  In addition you can set trap addresses and the
    default gateway via ELMS.  I think the commands are as follows:
    
    ELMS> SET device_name IP ADDR a.b.c.d
    ELMS> SET device_name DEFAULT GATEWAY a.b.c.d
    ELMS> ADD device_name TRAP ADDR a.b.c.d

432.2How the DB610's IP is implemented...BSS::C_OUIMETTEHolographic Interference RepositoryFri Dec 20 1991 11:0226
    	Thanks, Anil.
    
    For the rest of the community; I phoned Anil, and this is how the snmp
    agents in the DB610 work:
    
       Since the SNMP agents are always responders, and never initiators of
    SNMP messages (Unless they are sending traps, in which case the default
    gateway may be needed), they will always be answering SNMP requests from 
    NMS stations (preferably, MSU 8^)... The DB610 *always* remembers both 
    the Ethernet MAC source address & the IP Source address of the SNMP
    request, and simply sends puts it's reply into a ethernet packet with
    the above MAC address as the DESTINATION, and the above IP address as
    the IP destination. In this way, if the request came through a router
    (for instance, if subnetting's afoot), then the response will be sent
    back via the same router.
    
        I had my customer query the DB610 (after he put a manual ARP entry
    in), and the "ip address" query shows that the DB610 assumes a subnet
    mask based on the IP address class, in this case 255.255 for a class B
    address. But it apparently disregards the netmask when answering
    queries, as above.
    
    					Again, thanks Anil.
