No problem!
1.Configure Read/Write and read only SNMP community strings on all of your devices.
2. Create a user name and password with level 15 privledges in either your AAA server or all of your devices and limit its sessions to originate from only your Ciscoworks server.
3. Create or allow ACLs on each device so that information from each device can reach the ciscoworks server. The specific ports are listed at the begining of the installation guide.
4. Configure the default credentials on your Ciscoworks server to match #1 and #2.
5. Enter in the devices into Common Services.
6. I would suggest that you enable automanage devices from the DCR in all of your applications.
