4096.0. "A Bridge Too Far???" by JUNG::GALVIN (Mic, from chicaaaaaaago!) Tue Nov 17 1992 08:18

    	Couple Questions About Bridges
    
    Hi.  I have 2 questions regarding the BRIDGE AM.  1.)  Is the DECbridge
    600 supported?  If so, is there something special that needs to be done
    to register it?  All I did was give it the ethernet address, and it
    didn't get registered...  I can see it with NCP and it says it's
    reachable...
    
    2.) Is it an oversight that the BRIDGE AM was not included in the
    MCC_STARTUP_BMS.COM file?  I had to include it...  I had to enroll the
    BRIDGE AM everytime I started up the IMPM and something didn't look
    right, so I looked at this file to see how the AMs got setup and there
    was no BRIDGE.
    
    Thanks in advance.

    Shouldn't be anything special to register it.  You can see if it's
    reachable with the following two commands:

    MCC> test bridge <address>
    MCC> show station <address> all status

    If those commands both work, there shouldn't be any reason why you
    can't register it.

    MCC> register bridge <name> address <address>

    If you are having trouble, please post the errors you are getting.

    Um, it was a product marketing decision. :-)  The Bridge AM is no
    longer part of the DECmcc BMS package, you need to obtain the DECmcc
    ELM AM package to get the Bridge AM now.
4096.2I've got EMS V2.2JUNG::GALVINMic, from chicaaaaaaago!Tue Nov 17 1992 10:3315
    Ed,
    	I'm confused by your reply to the second part of my basenote...  I
    guess I should've stated that I'm working with EMS V2.2.  I have the
    ELM AM, however, I didn't *think* I was doing anything with it... Are
    you telling me that the icon I get in the toolbox comes from ELM?  
    	Also, that still doesn't explain why the BRIDGE_AM.EXE file is in
    MCC_STARTUP_BMS.COM....NOT! or does it?  
    
    confused...
    
    /Mic
    
    BTW, the error message I'm getting from the DECbridge 600 is that it's
    partially registered....thanks for your help so far!
    
4096.3ELM in EMS but not BMSTOOK::MINTZLKG2-2 near pole X3, cube 6072, dtn 226-5033Tue Nov 17 1992 10:388
Well, yes actually.

The bridge icon (and corresponding AM) is provided by the ELM kit.

The ELM kit is part of the EMS package, but not part of the BMS
package, and thus is not included in the BMS startup procedure.

4096.5DECnet V Router...?JUNG::GALVINMic, from chicaaaaaaago!Tue Nov 17 1992 13:2432
    Regarding the basenote, 4096, I have done some more research on the
    DECbridge 600.  Apparently, the customer has set it up as a Phase V
    Router.
    
    From NCP, I can see it's DECnet address, 1.501, however, I can't get
    any information on it, ie:  NCP TELL 'node' SHOW EXEC CHAR;  I suppose
    I need to run NCL?  And be on a DECnet Phase V node?
    
    Anyway, here's my current dilemma...  I tried to register this guy,
    using the BRIDGE AM, no luck...  I come up with partial registration...
    can't access node, (something along those lines).
    
    Next, I tried to register it as a DNA5 global entity, however, when you
    use the IMPM, the line for the ethernet address is inaccessible!  A
    bug?
    
    Next, I tried to register using FCL,
    
    FCL> REGISTER NODE 'nodename' ADDRESS=08-00-2B...
    
    I get a similar error message, regarding unable to access entity...
    
    Just for chance, I tried using the STATION AM, using the hw as well as
    the ethernet address...same results, and I event tried the DNA4
    AM...obviously same results...  Any ideas?
    
    thanks,

4096.6DECbridge 600 or DECnis 600 ?CHRISB::BRIENENNetwork Management Applications!Tue Nov 17 1992 16:003
Are you sure the beast is a DECbridge 600?

Could it be a DECnis ???
4096.7DECnis, yeah that's the ticket...JUNG::GALVINMic, from chicaaaaaaago!Wed Nov 18 1992 10:0712
    � Could it be a DECnis???
    
    BINGO!
    
    That's what it is.  Have you had any experience with it Chris?  If so,
    how do I register/manage/alarm....pray tell!  I'm on the edge of my
    seat... 8^).
    
    thanks,

4096.8ENUF::CAUDILLKelly - NaCM Tech Support - 264-3320Wed Nov 18 1992 11:172
    The DECNIS should be registered as a Node 5.  Then when you open it you
    will see the normal router-type stuff and some bridge stuff too.
4096.9I'm getting there...JUNG::GALVINMic, from chicaaaaaaago!Wed Nov 18 1992 15:077
    Hi.  What about if the DECnis has been setup as a Phase IV Router? 
    When I tried using the DNA5 AM, I believe I get a partial
    registration...  btw, if the icon comes up with a '.', does that simply
    mean we're talking Phase V jargon???  smile.  Thanks in advance.

The routing  algorithm  in  use has nothing at all to do with the management
protocol.

>     Hi.  What about if the DECnis has been setup as a Phase IV Router? 

It is  still  a  Phase  Vnode,  even  if  it is running the Phase IV routing
algorithm.

Make sure  you  can talk to it (using the synonym which is what DNA5 AM will
be trying to use).  Try using NCL to it.

The times  I  have  seen  this  are  because  the synonym information is not
usable (DECdns problems, etc.).

    Or, if you are not using DNS, maybe the node isn't defined in the local
    NCP database.  If NCL doesn't work either, I usually go with the
    following (even though it doesn't make sense) because sometimes NCL's
    error messages are not as meaningful as they could be:
    
    	ncp> tel <the-decnis> show exe
    
    Now, this error message is definitely going to fail because ncp cannot
    be used to talk to a DECNIS.  But it is the actual error that is
    important.  If you get:
    
    	%NCP-F-CONNEC, unable to connect to listener
    	-SYSTEM-F-UNREACHABLE, remote node is not currently reachable
    
    then you've got a network problem or maybe the DECNIS is defined with
    the wrong DECnet Phase IV address (or running with a different address
    than it is defined with).
    
    If you get:
    
    	%NCP-F-CONNEC, unable to connect to listener
    	-SYSTEM-F-NOSUCHNODE, remote node is unknown
    
    then the name isn't defined
    
    But if you get:
    
    	%NCP-F-CONNEC, unable to connect to listener
    	-SYSTEM-F-REJECT, connect to network object rejected
    
    Then you probably have the DECNIS defined in NCP properly and therefore
    the problem is in MCC somewhere.
4096.12DECnis access mucho slow...JUNG::GALVINMic, from chicaaaaaaago!Fri Nov 20 1992 17:2916
    Kelly,
    	Hi.  I got the  Network Object Rejected message, earlier, now I'm
    ok...FM, I guess?  I do have a question with accessing the DECnis using
    the DNA5 AM, how come it's so sloooooooooooooow!
    	I click on the DECnis icon, from the IMPM, go get coffee, walk
    about 10 minutes, and viol�, the child entities finally come on the
    screen...!
    	My configuration is EMS V2.2, VMS5.5-1, 36MG of Memory on a 3400,
    yeah I know...the CPU's too slow...but THAT slow?  I don't have any
    ALARMS polling, I don't have any EXPORTER jobs running, no HISTORICAL
    stuff....just barebones IMPM...any ideas?
    	A MONITOR SYSTEM *does* show CPU 100% flat out, but come on the
    DECnis is in the next roommmmmmmm!

4096.13seperate logical link for each operationENUF::CAUDILLKelly - NaCM Tech Support - office(ha!)=254-3320 - lab=264-1267Mon Nov 23 1992 09:0618
    I'm only another poor, dumb user, but my guess is this...
    
    From a terminal window, before you double click the DECNIS the first time, 
    do an NCP> ZERO NODE <the decnis> COUNTERS.  Then double click the DECNIS
    icon.  When it finally comes up, go back to the terminal window and do
    an NCP> SHOW NODE <the decnis> COUNTERS.  Check out how many connections 
    have been sent to the DECNIS during the elapse time.  
    
    My guess is that MCC is creating, using, and tearing down a seperate
    logical link for each of some long list of operations it does when you
    first open something.  For a very fast system and a lightly loaded
    router both being on the same lightly loaded LAN, this might not be
    completely terrible.  But it still amounts to sending aproaching three
    times the number of messages.  
    
    As to why MCC consume all the CPU time when you do this, who knows.
    But, don't feel too bad, it does the same thing to me and I'm using a
    VXT 2000 and a VAX 7000-610 with 128Mb and no other users.
4096.14Time for a changeRACER::daveAhh, but fortunately, I have the key to escape reality.Mon Nov 23 1992 13:481
Of course, all this changes with version 1.2-a of MCC.
