What object IDs (OIDs) does the Orion Platform poll for network topology information
Object IDs or OIDs are used to collect network Topology data. This article explains what types of network topology information the Orion Platform polls. Topology uses SNMP polling to retrieve CDP and LLDP data. Without these Layer 2 and Layer 3 data, Topology cannot map direct connections among discovered nodes. L2 OIDs L3 OID values.

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.

By default, SolarWinds Orion polls the following topology-related OIDs, as listed by type.
| POLLER TYPE NAME | OID NAME | OID VALUE |

| 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:
| ||
| 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. | ||
