    Hi,
    
    
    on my DECHub900 i start to play around with some FDDI components.
    I had no problems connecting 2 DECBridge900 via FDDI together (backplane 
    or FDDI-Cables). But when i try to connect a DECBridge900 to an
    DECConcentrator900 it only works externaly with FDDI-Cables. It dosent work
    on the DECHub900 backplane !
    
    What i have done:	set port A&B to backplane on the bridge, concentr.
    			create one FDDI channel in the LAN_Interc. window
    			connect the br and con to the FDDI-Channel
    
    What i hav seen:	DECBr900, FDDI Summary window, Status, 
    				CF State = isolated 
    			port a+b are grey (not green)	
    			UNA and DNA are 00-00-f8-00-00-00 ????
    
    			DECCon900 shows the same information
    
    One of my customers sees this strange FDDI-Addresses too 
    (00-00-f8-00-00-00) but he has a running FDDI connection via Backpl. !
    
    
    FW-Rev.	DECCon900 2.8, DECBridge900 1.4, DECHub900 3.1
    		HUBWatch (vms) 3.1.3, HUBWatch (WIN) X3.1.5 
    
    Is this a known problem ?
    Any ideas...
    Best regards, Andreas

|     The 00-00-f8-00-00-00 address means the UNA/DNA is unknown.  
    
    Your configuration consisting of a concentrator and bridge connected
    over the IMB should work (works for me).  Anything else that you can
    tell us ...

| 1896.2 | Just curious, what is the bridge Enet Address? | NETCAD::BATTERSBY | Tue Jan 17 1995 15:02 | 6 | |
|     Andreas, can you tell us what the MAC address of the bridge is?
    It's the 08-00-2B-...... address that's on the outside of the
    DECbridge box, or can be determined by looking at the bridge
    console.

    Hi,
    
    sorry for my slow response time, i was at customer site the last 2 days.
    
    Bill, thanks for explaning the XX-F8-XX address. I play a lot with the 
    HUB,Bridge and Concentrator. Set all FDDI port to the front panel.
    clear and create a new FDDI ring (IMB). Switch off and back on the
    whole equipment. Use another Bridge, but it doesn't work. 
    Maybe my concentrator is broken, but i can't check it because we have
    only one in Austria. (I already requested one from logistics) !
    
    Bob, the MAC Addresses from my 2 DECBridges900 are 08-00-2b-a6-5b-00
    and 08-00-2b-a6-8d-e8 !
    
    
    Thanks Andreas
