prerequisite/steps/configuration to add node to NNMi 9.20 (on device side from networking team)
We have few devices which are not discovered in NNMi 9.20 , can anyone guide me what configuration/steps we need to do on device so that we can add device to NNMi.
I am aware about how to add it to NNM but not sure about the steps from networking side.
I am not able to run snmpwalk from NNMi server.

in order to do more than just a ping, you have to enable SNMP on the devices. The read community is needed and it should not be "public". Perhaps you want or you have to add a manager entry, which allows only the NNMi server ip address to communicate with the device via SNMP.
As the commands are different for each vendor I can share some Cisco IOS stuff, which might be helpful:
access-list 55 permit host <ip of the NNMi server>
access-list 55 deny any
snmp-server community myspecialreadcom RO 55
snmp-server contact <contact information>
snmp-server location <location information - can be used for Node Group filtering>
snmp-server enable traps
no snmp-server enable traps snmp authentication
snmp-server host <ip of the NNMi server> public
! public for sending SNMP trap is ok!
HTH and kind regards
