Um, I might be off base here, but EVERY TCP/IP device has a routing
table.

        Have you tried configuring one of your 5024s to actually disable
the routing capability?  I would be curious to see if that would get rid
of the routing table information.

Subject: [nv-l] Switch Analyzer and Layer 3 switches    



        Greetings all, 
        
        The subject is ominous but here is my situation. 
        
        We haev some Alcatel 5024's. These devices by default have some
built in routing capabilites. As such they contain a routing table where
populated or not it is still there, however these devices are trully
only being used as a layer2 switch; but Switch Analyzer is not
recognizing them as such. The reason I found out from Magnum is that One
of the means by which netview determines a device to be a router is if
it contains a routing table. Well the moment it finds the table ont hese
devices it calls it a router and switch analyzer will not attempt to do
any layer2 discovery on it. 
        My question is, is there a way to override Netviews discovery
and force these devices to show as layer2 devices only? In the
oid_to_type this particular device is listed as a HB (Hub Bridge) with
no mention of G(gateway). 
        
        Thanks 
        Chris Petrina
