Search for network addresses

SolarWinds NCM can search the entire database (Nodes table, IP Address table, ARP tables, BridgePorts and MAC Forwarding tables, Interfaces) for specific network addresses.

For the best results, add all switches and routers to SolarWinds NCM, and always update your inventory prior to a search, especially when searching for a MAC address.

How does NCM find addresses?

During node inventory, the following tables are populated in the Orion platform database:

Table

Description

Nodes Table Stores a list of all nodes managed by SolarWinds NCM, along with the declared node properties.
IP Addresses Table Stores a list of IP addresses mapped to interface and node IDs.
Interfaces Table Stores a list of interfaces, interface indices, interface types, and interface descriptions mapped to node IDs.
Bridge Ports Table Stores a list of bridge ports, spanning tree status, spanning tree state, VLAN type, and VLAN ID mapped to node IDs.
MAC Forwarding Table Stores a list of MAC addresses, ports, and how the address was mapped to node IDs.
ARP Tables Stores a list of data returned from ARP tables and mapped back to node IDs. This information includes interface index, interface ID, MAC address, IP address, and whether the IP address is static or dynamic.

When you search for an IP address, a hostname, or a MAC address, SolarWinds NCM searches these tables for the value and returns all matches.

Where appropriate, returned values include a ranking which reflects how often a MAC address appears in the ARP table for a given port.

If you are searching for a MAC address that is part of a VLAN, the results may incorrectly display a rank of 0 for the address.

If you are only managing switches with SolarWinds NCM, IP addresses will not be returned by the search.

Find IP addresses

  1. Click My Dashboards > Configs > Config Summary.
  2. Under Search NCM, type the address pattern you want to find.

    For example, 10.199.[2-12].[10-200], searches for nodes 10-100 in the subnets 10.199.3.0 through 10.199.12.0.

  3. Click Search.

Find MAC addresses

You may need to search all of your configuration files, for example, to see if a MAC address is included in any black lists.

  1. Click My Dashboards > Configs > Config Summary.
  2. Under Search NCM, type the pattern you want to find.
  3. Click Search.

Find hostnames

If you network supports DNS, you can search for NCM nodes by hostname.

  1. Click My Dashboards > Configs > Config Summary.
  2. Under Search NCM, type the pattern you want to find. SolarWinds NCM automatically searches on the string in any part of the current property value(s) in the database.
  3. Click Search.
