Ping Sweep and Discovery in LMS 4.1

Hello Community,

we are running CiscoPrime LMS 4.1 and I have a problem with PingSweep in Device Discovery.

Our company's branches connect to the main site through GETVPN. Discovery through CDP, Routing Table and ARP cannot be used based on the document written by Joseph Clarke (https://supportforums.cisco.com/docs/DOC-9005) and which is extemely helpful.

So the only available option is PingSweep.

The loopback interfaces of all the remote GETVPN devices are in the same IP range, so this was configured in Module Settings --> Ping Sweep in the Discovery.

Unfortunately none of the devices get discovered, even though there is icmp connectivity from the server to the loopbacks.

What could be the problem and how can we further troubleshoot?

Thanks in advance,

Katerina

Ping Sweep and Discovery in LMS 4.1

I would like to update the post...

The problem was that in Discovery Settings --> Filter Settings I had excluded the IP addresses, which indicated the connected between our routers and the ISP CPE. As a result the Discovery did find the routers in question, but "rejected" them because one of the interface IPs was found in the "exclude filter".

Everything is working fine now.
