You have total control over which Nodes are discovered by configuring a Discovery Seed for each Node. To define a Discovery Seed, you provide one of the following sets of information:
hostname ( not case-sensitive) and Tenant
IP address and Tenant
NNMi uses the Discovery Seed to make initial contact. Discovery seeds are only relevant during initial discovery. NNMi requests each Node's current Management Address (the address from which the node's SNMP Agent responds) and uses that IP address for all communication after initial discovery. You can configure discovery seeds three ways,
Dynamic discovery process continues over time. When things change in your network management domain, Spiral Discovery automatically updates information according to a schedule that you set. The topology maps always reflect accurate and timely information about any changes within your network.
