Exclude Devices from Discovery

  • To prevent discovery of certain object types, create an auto-discovery rule with a low ordering number that ignores the system object IDs that you do not want discovered. Do not include an IP address range in this rule. By giving this auto-discovery rule a low ordering number, the discovery process quickly passes by the objects that match this rule.
  • The Ignored by Rule setting for an IP address range or a system object ID range affects that auto-discovery rule only. The devices included in an ignored range are available to be included in another auto-discovery rule.

Note Some networks use routing protocols such as Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) to provide router redundancy. When routers are configured in an router redundancy group (RRG), as they are when using HSRP, the routers configured in the RRG share a protected IP address (one active and one standby). NNMi does not support the discovery and management of multiple RRGs configured with the same protected IP address. Each RRG must have a unique protected IP address.
