Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Simple Network Management Protocol

Network management stations use simple network management protocol (SNMP) to retrieve and modify software configurations for managed objects on an agent in network devices. A managed object is a datum of management information.

The SNMP agent in a managed device maintains the data for managed objects in management information bases (MIBs). Managed objects are identified by their object identifiers (OIDs). A remote SNMP agent performs an SNMP walk on the OIDs stored in MIBs on the local switch to view and retrieve information.

OS10 supports standard and private SNMP MIBs, including all get requests. MIBs are hierarchically structured and use object identifiers to access managed objects. For a list of MIBs supported in the OS10 version running on a switch, see the OS10 Release Notes for the release.

OS10 supports different security models and levels in SNMP communication between SNMP managers and agents. Each security model refers to an SNMP version used in SNMP messages. SNMP versions provide different levels of security, such as user authentication and message encryption.
