We have LMS 3.1 installed on a server and are trying to discover/import network devices that we wish to manage. When I configure the Device Discovery parameters (CDP, IP address, SNMP community) and click Start Discovery the page just refreshes without finding anything. These parameters are the same as configured on the network devices. The network devices are ping-able from teh LMS server and there are no access lists/firewalls between them. Can anyone suggest what I may be doing wrong?
