    Hi,
    
    COuld we use DECmcc ELM AM to disable/enable the spanning on LB200 (I
    mean turn-off the spanning other than change it from auto-select to IEE
    802.1)?
    
    If not, how could we do it (using MOP, etc..)?
    
    
    Thanks

Why on earth would you ever want to disable spanning tree ??? This could have disastrous effects on your network. I don't believe that any of our bridges would support this. *Robert | |||||

    No you can not turn off the STP on the LB200.
    
    re .1
    
    The GIGAswitch is essentially a 100Mb bridge. V2.0 includes an SNMP
    object, gigaStpPortSpanningTreeEnable, that allows the user to turn off 
    spanning tree.  There is a discussion of the pros/cons in the 
    SCHOOL::GIGASWITCH conf (I don't have the entry #).    
    
    V2.8 of the DEC ELAN Vendor MIB includes an object,
    ebrIfSpanTurnOffStatus, that can be used on DEC bridges that support
    this version of the MIB.  I beleive this functionality is planned for the 
    DECbridge 900.
