Accepting Network Elements


(sorry for my bad english)

I have a little Problem when I want to accepting SMs.

With some SM i become this message:

"Error determining Element Type via SNMP. Element could not be added for Management"


"Element not accessible via Discovered Parent. Unable to configure the Element via Parent LUID Select"

Can anybody help me?

We use Prizm 3.1 and we need to manage over 1000 SM and 600 AP(100 CMM)

Thanks al lot
