LMS 2.6 device discovery?

I am trying to get everything discovered on the new lms2.6 server. I have gradually opened up the ip ranges for discovery but something is off. I am stuck at 272 Devices in the L2 map. When I look at Campus mgr home I see 342 devices discovered.

Thanks for any advice

Re: LMS 2.6 device discovery?

What is the status of these devices? Are all 342 reachable and known? If you click on the number 342 in Device Discovery you should see a list of the devices it picked up.

you can then see why there is a discrepancy, perhaps some devices are not reachable.

I did that and 14 are in an unreachable state. Most of those are firewall related issue that I am dealing with. So I am still puzzled about the remaining that are reachable but do not populate the map

Re: LMS 2.6 device discovery?

Here's what you can do to troubleshoot:

Start with 1 device that is missing from the map and is in the other list:

- Is it in a reachable state?

- Is it a supported device? Some devices can be snmp and cdp supported, but not supported by the app

- Are the snmp comm strings correct? Can you snmpwalk it from LMS?

- Is CDP enabled?

If all of the above are correct then:

- Add it as a seed device? Does it appear?

- Is it on the other side of a firewall? Remember firewall won't pass CDP (layer 2)

If it still doesn't work then you may want to enable debugs in CM
