I run LMS 2.6. I am having an issue with end devices on some 4503's not being discovered. My 4506's run the same IOS and the same configuration and are listing all end devices. I checked cdp in the switches and all see their neighbors, but in Device manager in LMS, the cdp neighbor is blank. I checked snmp etc. Everything else in LMS is populating for these switches, just not end devices. I've run Data Collection few times. Still nothing.
Any suggestions or help would be appreciaed.
