633.0. "workgroup/backbone port down" by ODIXIE::RICHARDSON (Are we there yet??) Tue Jan 18 1994 08:58

    I've sure been putting my share of entries in here lately - but here
    goes another....
    
    I have a bridge90 that keeps giving "workgroup port down", "backbone
    port down" errors using Hubwatch for Windows software.  
    
    The Agent is V1.1, the Bridge is V3.1 firmware.  From the agent's point
    of view (console) the bridge has the correct MAC address and I can
    connect to it with no problem.  The bridge is working correctly and has
    been powered cycled since the agent was added (the entire hub was
    cycled with the agent and bridge in the hub).  They are in slot 7 and
    8.
    
    I did initialize the database and do an auto discovery and it finds the
    bridge along with all the other repeater 90T's in the hub.  Everything
    looks fine until the first time the bridge gets "polled" and I get the
    red light with the two errors mentioned above.  The thinwire port
    onethe bridge is connected to a DELNI which in turn is connected to the
    backbone and all the PC's on the repeaters in the hub can talk to the
    servers on the backbone so I really don't think that both the backbone
    and workgroup ports are down.
    
    So...I'm all out of ideas.  The HUBwatch version is 1.1.
    
    Any Suggestions?

633.1Couple of Things to TryLEVERS::DRAGONTue Jan 18 1994 09:1617
    
    Cindy,
    
    	A couple of things which you might try.
    
    1) Using the DECagent 90 V1.1 console see what the DECagent 90 says about
       the DECbridge's port status
    
    2) Perform a MOP connect to the DECbridge (from the DECagent 90) in 
       question and use its console command to see what the DECbridge says 
       about its port 1 and 2 status (SHOW PORT 1 and SHOW PORT 2). Also see 
       if you get any loopback diagnostic failure messages (pg 4-21 DECbridge 
       90 Owner's Manual) which may indicate configuration/cabling problems. 
       Also, do the DECbridge's LEDs indicate any problems?
    
    Hope this helps,
    Bob
633.2Common Problem?ALBANY::BARTLEYThu Jan 20 1994 09:4229
    I too have seen the same scenario as Cindy. I upgraded the DECagent 90
    to V1.1 and the DECbridge 90 to V3.1 and am running HUBwatch V1.1 on 
    a DECstation 333 (a little slow for HUBwatch).
    
    I connected to the bridge through the DECagent and showed both ports. 
    Disabled state:0 and Broken state:0 on both ports.
    
    Port 1: 08-00-2b-31-cb-64
    Port 2: 08-00-2b-71-cb-64
    
    I went back to the DECagent and did a Show Module. The agent showed the 
    bridge as having an address of 08-00-2b-32-67-87. Where it got this
    address I don't know. I changed the address in the agent and went back 
    to HUBwatch and got the same results. 
    
    Alarms were:
    
    Agent - (min) Threshold:SNMPOutGenErrs
    Bridge- (maj) Bridge Backbone Port is Down
    Bridge- (maj) Bridge Workgroup Port is Down
    Module2-(min) Threshold:DS90lDot3StMultiColl
    Module2-(min) Threshold:DS90lIllglMutlicast
    
    All LEDs Green (no errors).
    
    What are we doing wrong??

633.3Methinks the agent is confusedQUIVER::GAUDETThu Jan 20 1994 14:099
    That's very strange.  Can you remove and re-add the bridge, either at
    the agent's console or through HUBwatch?  I have no idea where the
    agent would be coming up with an obscure address for the bridge.
    
    Failing that, perhaps a bit more detail about your configuration would
    help us figure out what's going on.

    Someone here in the Office suggested to SET BRIDGE HUB_MANAGE DISABLE.
    I tried this, and no change.
