Hello,
I am building CiscoWorks LMS 3.2 from scratch and my two Call Managers come up as unreachable devices. I've done some searches and found plenty of Cisco documentation speaking about CDP settings for Call Manager but nothing that tells me where to view it or change it. Can someone tell me what menus I should be looking at in Call Manager in order to verify the SNMP settings?
Any other reason CiscoWorks would be unable to reach these CMs?
Thanks,
Mike

if the CallManager is marked "unreachable" it is not a problem with CDP. CDP is necessary to find the hardware - this step passed (because it is listed). The next thing that must work is SNMP reachabiliy and this fails. So either the Call Manager has no SNMP community configured or LMS does not know the correct community to use.
If both are ok, access-lists or firewalls are typically blocking SNMP traffic.
here is the documentation for the Call Manager that covers this
Simple Network Management Protocol Configuration
see the section Configuring SNMP Security
