|  |     I've never heard of NAT bridges.  They definitely will not use
    Digital's proprietary RBMS protocol, so DECmcc ELM will not be able to
    access them.
    Do NAT bridges have SNMP agents?  What MIBs do they support?  You'll
    have to look at the bridge documentation to find out.

    Hi Ed,
    
    I'm working with Pierre on the second part of the problem. 
    You're right, NAT bridges are only managed via SNMP Access Module.
    
    Our problem is how the ELM Functional Module (ie STP Listener process)
    works. It detects DEC bridges and VITAlink bridges, but not NAT bridges
    which are in the same topology (same Spanning Tree algorithm).
    
    Is the STP process auto-configuration principle based on Spanning Frames
    exchanged between all the bridges (DEC, VITALINK, NAT...) ? Which
    version (DEC STP or/and IEEE 802.1d) ?
    
    Regards,
    Renato

    No, the listener find bridges by listening for MOP SYSIDs.

	The question is can you ping the nat box from the system running
	DECmcc? If you can, then registration should be successful. Note
	that partial registration can occur if the SNMP AM cannot find an
	internet name for the specific device from the domain name server.
