SNMP Monitoring

Simple Network Management Protocol (SNMP) is an application-layer protocol for monitoring and managing network devices across the network and receive notifications (SNMP traps).

Note: Validation Responder Appliance supports SNMPv3.

SNMP's client-server architecture has the three following components:

  1. SNMP Manager: Acts as "Client".

  2. SNMP Agent: Acts as "Server".

  3. Management Information Base (MIB): Acts as server’s "Data base".

When the SNMP Manager (client) send a query to the SNMP Agent (server), then the agent uses the MIB data base to provide the response for that query. Refer to Net-SNMP tutorial for SNMPv3 for basic details about SMNPv3.

Each object in the MIB is associated with an object identifier (OID), which is an unique identifiers to classify objects defined in MIB files for each managed device. For example: sysUpTimeInstance (1.3.6.1.2.1.1.3.0).

For SNMP MIBs data, refer to MIBs Supported by VRA for SNMP Monitoring.
