    Want to see your cisco CDP?

          It's a fun project to build and run a CDP Neighbor report and get the output into Excel format.  I just ran one earlier this week for a Manager, to show how many CDP relationships there are.  The number was 3744, and it was a user-friendly and tightly efficient page that showed every device and its relationships to all other CDP neighbors.

           

          Write me if you're interested in the Python scripting to generate the full network's list of all CDP neighbors/interfaces/relationships and I'll post it.

           

           

           

           

          You can also add CDP Neighbor as a Widget into all your NPM Node views by adding this Custom SWQL into a resource added onto your NPM page:

           

          SELECT I.InterfaceName AS [Local Interface], CDP.IPAddress AS [IP Address], DeviceId AS Device, DevicePort AS [Remote Interface], (SELECT N2.DetailsURL from Orion.Nodes N2 JOIN Orion.NodeIPAddresses NIP ON (N2.NodeID = NIP.NodeID) WHERE NIP.IPAddress = CDP.IPAddress) AS [_LinkFor_Device]

          FROM Orion.NodeCdpEntry CDP

          JOIN Orion.Nodes N ON (N.NodeID = CDP.NodeID)

          LEFT OUTER JOIN Orion.NPM.Interfaces I ON ((CDP.NodeID = I.NodeID) AND (CDP.IfIndex = I.Index))

          WHERE (CDP.NodeID = ${NodeID}) AND (N.IPAddress <> CDP.IPAddress)

           

           

          The output looks like this (on a Distribution switch with several hundred CDP neighbors):

           

           

           

          A single, smaller Access Switch, with only fifteen AP's on it, and a couple of uplinks or downlinks, is a simpler view:

            Here's a fun script for getting this information:
