I am trying to write a query that will tell me all the devices on a particular network device as well as a report that will tell me where a host is on the network (Interface and network device its attached to).
I do nightly inventory grabs on all my network gear...I grab the ARP table as well as the bridge/mac table. We have a layer 3 core network with layer 2 access switches off these cores. The ARP table can give me the IP addresses from the core switches but not on the access switches and it shows the interface as the layer 3 vlan..not the actual interface its on.
The bridge/mac table gives me interface level information about mac addresses and where they are connected but I dont have IP info to match it up to.
I tried to do a SQL join on these two tables in order to get the info I need but the interface indexes don't seem to match up....so I don't see a way to do this type of report.
Can someone help me please!
