4864.0. "Access Module of Function or Both?" by SKULLY::COMPTON (Dorie) Mon Apr 12 1993 16:31

    Are there some guidelines that can be used as to when you want to write
    an Access Module and when would you want to write a Function Module?
     
    It seems that if I had a CMIP and/or SNMP Access Module then I should
    just need to write Function Modules, but there are examples like the
    bridge access module that does SNMP and the circuit access module...
     
        Could someone please help clarify? 
     
     			Thanks.

4864.1	What is it you'd like to do ?	MOLAR::ROBERTS	Keith Roberts - Network Management Applications	`Mon Apr 12 1993 18:13`	14
	Typically an Access Module allows the DECmcc 'access' to a specific technology. The AM converts management requests from DECmcc to the appropriate protocol and back again. The AM also (optionally) gathers Event data and pumps it into MCC. Functional Modules talk to other FMs or AMs (not to technology specific things). The FM adds 'functionality' to the system .. like Alarms, Historian, Exportor, and the Performance Analyzer. Making sense? So .. what is it you'd like to build ? /keith
4864.2	more information on AM vs FM	KAJUN::NELSON		`Tue Apr 13 1993 09:56`	21
	Just an additional note to -.1... As Keith said - usually - AMs are technology-specific and FMs are more generic. However, you can also look at it with a slightly different view: An FM might make sense if you want to supply a value-added service such that the application may have to make several calls for information to satisfy the user request. These calls may be to a single or to multiple devices or may be to other application services. The user makes a single request and the FM orchestrates the gathering of information to satisfy the request. This FM may be . technology-specific . generic in the sense that it may apply to any technology, but only one per request, . may require information from mulitple technologies to satisfy a single user request. ...kjn
4864.3	Bridge AM speaks ELM protocol.	MOLAR::MOLAR::BRIENEN	Network Management Applications!	`Tue Apr 13 1993 14:54`	11

The Bridge AM only speaks the Extended LAN Management protocol, not SNMP. Some of our bridge Agents (e.g. DECbridge 6xx) speak both SNMP and ELM.
