1796.0. "MIB Questions" by ROM01::LILLI () Tue Nov 12 1991 06:42

I suppose to integrate a private MIB as a MIB extension within the DEC SNMP
Access Module.

The questions are:

1) will I develop an agent that is able to manage only the objects I define?

2) will I develop an agent that is able to manage all the objects in the MIB
(the standard objects and mine)?

3) can I integrate the agent for my objects with an existing one?

4) will I have two agents available on a server one for my objects ( developed
by me) and another one for the standard MIB?

In the case my view is on all the MIB objects (mine and standard ones) and I
have more than one agent, how can the Access Module contact the right agent?
RFC 1157 defines port 161 and 162 for SNMP requests.

    Ok, These questions are basic to agent development. I will assume that
    the development platform is VMS or Ultrix. I will also look somewhat
    forward in time rather than what is immediately available today.
    
    Digital has developed some new technology called the Common Agent which
    will shortly be included in both the VMS and OSF1 (aka Ultrix)
    operating systems. The VMS common agent is being developed by the
    VMS systems management group (send mail to Maribeth Marcello) and
    the OSF1 common agent is being developed by OSG (send mail to
    DECWET::Fries). For OSF1, all you need supply is a management object
    module for your MIB extensions and have it included. The basic
    common agent provides MIB II basic support. There are some
    restrictions about how you link a MOM to the agent. For VMS, the
    MIB II support is not currently in the kit, so you would need to
    negotiate that with Maribeth and her people.
    
    If you choose to go with what is immediately available. You need
    to on Ultrix provide an agent with both MIB II and your extensions.
    I caution you to check within OSG and make sure that your
    implementation will not collide with what they are also currently
    doing.
    
    I highly recommend you taking the common agent route. 
    
    If you are going for a Unix implementation, I would suggest getting
    in touch with Brian Handspicker and Steve Wong in the EMA architecture
    group and work with them on your proposal.
