2516.0. "Does DB90FL support ELMS?" by MOLAR::BRIENEN (Open Network Management Group) Thu Jul 13 1995 18:06

    I was under the impression that the DECbridge 90 (along with the LB100,
    LB150, LB200, and DB 5xx/6xx) supported the "old" ELMS protocol.
    
    Recently a customer reported that the DECbridge 90FL was manageable
    with ccr, but elms didn't seem to work.
    
    Does the DECbridge 90FL support the ELMS protocol?

2516.1not ELMS, but ELM AM?NAC::FORRESTThu Jul 13 1995 18:406
    Chris, I think the DECbridge 90 came out after ELMS reached
    end-of-development-life. I think support was included in the DECmcc ELM
    Access Module. Anyway, the DECbridge 90 does speak what I call the RBMS
    protocol. That is what the DECagent 90 uses to SNMP proxy for it.

2516.2Not Supported under ELMS or ELM-AMMSDOA::REEDJohn Reed @CBO = Network ServicesFri Jul 14 1995 00:5013
    Watch out for the 90FL using the ELAM.    
    
    You can partially use POLYCENTER Network Manager to see STATUS and
    COUNTERS, but not Characteristics of the DB90FL.   The DB90 seems
    to behave nicely under ELAM.   When  you register the 90FL, it will
    time out with an obscure error about being interrupted in the middle of
    the process.   But it will show up, and you can look at counters and
    status usng the FCL, (but not the ICPM).   If you are looking for
    graphical representation of the device stick with HUBwatch....
    
    If  you want the alarms, and counter data, he ELAM will work.

2516.3PDM elmsMOLAR::BRIENENOpen Network Management GroupTue Jul 18 1995 20:3923
    Thanks for the feedback!
    
    The application I'm currently working with is the elms command line
    that ships with POLYCENTER DECnet Manager (PDM), which layers on top of
    POLYCENTER Netview (PNV). This elms was ported from MSU, and is running
    on Digital Unix and NT.
    
    It seems to work fine with the DB90s (DEWGB) we have on the local
    ZKO LAN, but the customer (and DEC support person who has a test
    LAN with DB90s and 90FLs) can't get elms working to them. Connecting
    to them via ccr works fine. 
    
    Since the Bridge Topology code in PDM uses either ELMS or SNMP (mib II
    and bridge mib) to query for interface/spanning tree information, the
    90's never correctly appear on their bridge map.
    
    From Jack's response, the DB90/90FL should at least be supporting the
    mini-ELMS protocol for the DECagent90, so the problem must lie some-
    where else.
