Hey Everyone -
I am running LMS 3.0 and having some trouble getting new devices added to my system. In the inital setup I was able to successfully add 3 devices from one range of IP addresses. I just added a few more IP addresses, made sure they all had public ro / private rw strings, and ran the device discovery. They are not being discovered though. Does anyone have any ideas as to why the original 3 devices were picked up right away through device discovery, but now I can't seem to get it to recognize anything else?
Also, the devices are 2 x 2950 and 1 x 3560 switches. I have 3 of the same devices already setup.
Thanks in advance for the help!

Device Discovery requires CDP, ILMI, or ELMI to find neighbors. If you do not have those protocols running between your seed devices (including those already in DCR) and these new devices, then discovery will not find them.
If CDP is running, you can enable devdiscovery debugging under Campus Manager > Admin > Debugging Options > Device Discovery, re-run the discovery, and the discovery.log will have more information.
According to this, there are three seed devices, 10.0.07, 10.0.0.6, and 10.0.0.8. Each device on;y has each other as a CDP neighbor, so there are no other devices for discovery to find. Your missing devices must be neighbors of one of these three devices for discovery to find them.
The 3 devices already in LMS are all in the same physical location. The other 3 devices I am trying to add are on the same network, but in different physical locations...as in, a completely different state in the USA.
10.0.32.2 & 10.0.32.3 are neighbors.
192.168.16.2 is a single switch.
What do I need to do to get them added?
I have all the IP Ranges set in Discovery Settings. To add the devices as a seed device do I just need to upload a text file with each device's IP Address in it?
