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. NOTE: OS10 does not support SNMP SET operations. Configuration notes All Dell EMC PowerSwitches except MX-Series, S4200-Series, S5200 Series, and Z9332F-ON: ● SNMP server is supported in non-default (data) VRFs. Dell EMC PowerSwitch S4200-ON Series: ● SNMP server is supported in non-default (data) VRFs. SNMP security models and levels OS10 supports SNMP security models v1, v2c, and v3. The supported security levels are no authentication, authentication, and privacy. You specify the SNMP security model and level when you configure SNMP groups and users. Each security model corresponds to an SNMP version that provides different security levels: ● SNMPv1 provides no user authentication or privacy protection (encryption). SNMP messages are sent in plain text. ● SNMPv2c provides no user authentication or encryption. SNMP messages are sent in plain text. ● SNMPv3 provides user-configured security levels for user authentication and encryption of SNMP messages: ○ No user password or message encryption ○ User authentication only ○ User authentication and message encryption The supported characters for SNMP user password are ● A-Z ● a-z ● 0-9 MIBs OS10 supports the following standard and Dell EMC enterprise MIBs.
