A spectrum Discovery Configuration is configured to only model Pingable models. The parameters are set as follows:
SNMP Community String set to a "bogus" value so no devices in the range will respond successfully to snmp queries.
Set to model to a specific container
All Modeling Option deselected
All Protocols deselected in the Protocol Options window
All Services deselected in the Network Service Options
Use ICMP first, then SNMP checked.
Use Route Tables unchecked
After running this Discovery Configuration, one of the Pingable models is resolved to the router port of one of the routers.
Release : Any
Component : Spectrum Discovery & Modeling
The discovery process is making use of Address registry, getting the router ips and matching with the pingable ip and its network mask.
If a match is found, it makes the connection.
Set the lockPort attribute id 0x133e8 on the router port to Yes. Setting the value to Yes tells the discovery process to not make a connection to this port model.
