True I should have specified more.  Routing table and IP Forwarding enabled

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

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

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
