    subnet discovery: what devices are supported?

    familyofcrowes

      When using subnet discovery, I find that I can pull the table from my "routers" but not my layer 3 switches.  We summarize our tables so I need to pull subnets from each of my 4507's or 3560's to get the sites "none summarized" routing table.  BUT, each time I do this I get zero subnets returned from the layer 3 switches.

          Hi Napoleon,

           

          you can check if your L3 switches respond to these OIDs:

          1 - ISO assigned OIDs

          1.3 - ISO Identified Organization

          1.3.6 - US Department of Defense

          1.3.6.1 - OID assignments from 1.3.6.1 - Internet

          1.3.6.1.2 - IETF Management

          1.3.6.1.2.1 - SNMP MIB-2

          1.3.6.1.2.1.4 - ip

          1.3.6.1.2.1.4.1 - ipForwarding

          1.3.6.1.2.1.4.1 - ipRouteTable

           

          if so, please send us SNMP walk (use my email) and we will reproduce behavior in our lab.
