Not discovering devices

When I run a discovery the server will not find all the devices. It finds a few from each ap but not all of them.


Here are a few questions to help debug.

1. From the machine running CNS Server, can you ping the problematic devices ?
2. Are the SNMP community strings set the same on the devices and on CNS Server ?
3. Can you use a 3rd party tool (i.e. NetSNMP) to confirm that SNMP communication to the device is working without CNS Server ?

If the above do not provide useful information, check the “Events Log” in the CNS Server “Discover” section. Filter based on the problematic device (i.e. MAC) to see if there are any discovery-related messages.

Lastly, what version of ePMP and CNS Server are you using ?
