    The short answer is yes. The VNswitch 900EX Fast Ethernet ports can be
    manually configured or auto-negotiate to:
    	10Base-T Full Duplex
    	10Base-T Half Duplex
    	100Base-TX Full Duplex
    	100Base-TX Half Duplex
    
    During development I tested the VNswitch EX with the DE500-AA and I
    verified that it could auto-negotiate to all of the above modes in this
    configuration.

    Are you sure the the VNswitch is configured correctly. For example, is
    auto-negotiation enabled (this is the default state).  A more basic
    question is are you sure you have the correct type of cable? You need a
    cross-over cable when connecting the VNswitch Fast Ethernet ports to
    and end station. Also, is auto-negotiation enabled on the DE500-AA?
    
4313.2all seems goodPRSSOS::PEYRACHEJean-Yves Peyrache Country Support Group FranceThu Mar 27 1997 11:529
     thanks for your reply,
    
     unfortunatly DE500 and EX seems configured as well,
     cable works great as 10 Half and Full and 100 Half but no in 
     100 full.
     
     any ideas ?
