What object IDs (OIDs) does the Orion Platform poll for network topology information

Table of contents

Overview

This article references the object IDs (OIDs) used to collect network Topology data.  It also explains what types of network topology information the Orion Platform polls.  


Note: All data is gathered on the rediscovery interval. The IP address information is gathered from all nodes.  

Environment

  • SolarWinds Orion Platform Version 2011.2 and higher

Detail

By default, SolarWinds Orion polls the following topology-related OIDs, as listed by type.

Description
N.Topology.Snmp.Layer2 dot1dTpFdbTable 1.3.6.1.2.1.17.4.3
A table that contains information about unicast entries for which the bridge has forwarding and/or filtering information. This information is used by the transparent bridging function in determining how to propagate a received frame.
N.Topology.Snmp.Layer2 dot1dBasePortTable 1.3.6.1.2.1.17.1.4
A table that contains generic information about every port that is associated with this bridge. Transparent, source-route, and srt ports are included.
N.Topology.Snmp.Layer2 dot1qVlanCurrentTable 1.3.6.1.2.1.17.7.1.4.2
A table containing current configuration information for each VLAN currently configured into the device by (local or network) management, or dynamically created as a result of GVRP requests received.
N.Topology.Snmp.Layer2 vmMembershipSummaryTable 1.3.6.1.4.1.9.9.68.1.2.1
A summary of VLAN membership of non-trunk bridge ports. This is a convenience table for retrieving VLAN membership information.

A row is created for a VLAN if:
  1. the VLAN exists, or
  2. a port is assigned to a non-existent VLAN.
VLAN membership can only be modified via the vmMembershipTable.
N.Topology.Snmp.Layer3 ipNetToMediaTable 1.3.6.1.2.1.4.22
The IPv4 Address Translation table used for mapping from IPv4 addresses to physical addresses.

This table has been deprecated, as a new IP version-neutral table has been added. It is loosely replaced by the ipNetToPhysicalTable.

Node details poller for devices which support RFC1213-MIB and IF-MIB utilized in node rediscovery Poller utilizes GET-REQUEST to gather basic details about node using OIDs:
  • sysObjectID = 1.3.6.1.2.1.1.2.0
  • sysDescription = 1.3.6.1.2.1.1.1.0
  • sysName = 1.3.6.1.2.1.1.5.0
  • sysLocation = 1.3.6.1.2.1.1.6.0
  • sysContact = 1.3.6.1.2.1.1.4.0
Poller is able to recover if some of OIDs mentioned above are missing. OID sysObjectID is the only one that is required. Poller utilizes GetSubtree request to gather all MAC addresses from device using OID: interfacesMAC = 1.3.6.1.2.1.2.2.1.6
