Question : HP Procurve Manager SNMP Discovery

I've installed HP Procurve Manager software, but most of my devices have not been discovered and when I go to Network Map it says "A Network Map does not exist because, Topology Discovery has not run"

I've specified the subnet as IP 192.168.1.0 mask 255.255.255.0.

Answer : HP Procurve Manager SNMP Discovery

Is this a 'lite' version of OpenView?
If so, have you configured autodiscovery?
You may also need to manually add your local router as a seed.
