3386.0. "PORTswitch900FP config. problem" by STU03::RUEGGEN () Thu Mar 21 1996 04:48

    Hello,
    
    I have a problem with a Portswitch900FP configuration.
    
    Portswitch900FP in DEChub900. All ports are in group 1 and 
    thinwire connection is to port 1-2.
    DEChub900 also contains DECrepeater90T. Four VAX 4500 are connected
    to this repeater.
    LWL connection via port 1 to other Portswitch900FP in a DEChub900. 
    Port 2 is redundancy for port 1.
    LWL connection from port 3 to LWL-AUI transceiver in Lanbridge150. This
    then connects to a LAN-segment.
     
    Machine on this LAN-segment connected via port 3 tries to access either 
    VAX 4500 over DECnet or LAT. Connection establishment takes up to 2 minutes
    or times out. If this machine connects via port 3 and then port 1 to
    other DEChub900 there is no problem.
    
    Connectivity via port 1 from other DEChub900 to those VAX 4500 works O.K.
    
    If I install a DEFAR into the HUB and take the LWL from 900FP port 3
    to this device the problem disappears.
    
    Is there a misconfiguration here ?
    
    Thank you for any help

    Hello Uli,
    
    Is it possible that your problem has something to do with illegal
    repeater redundancy. I have asked a question about repeater redundancy
    in note #3387.
