Security Models

Registration Procedure(s)

  • Standards Action

Reference

  • RFC 3411: An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks

Note

The SnmpSecurityModel TEXTUAL-CONVENTION values managed by IANA are in the range from 0 to 255 inclusive, and are reserved for standards- track Security Models. If this range should in the future prove insufficient, an enterprise number can be allocated to obtain an additional 255 possible values.

There are several values of securityModel defined for use with SNMP or reserved for use with supporting MIB objects. They are as follows:

Available Formats

Value Description Reference
0 reserved for 'any' RFC 3411
1 reserved for SNMPv1 RFC 3411
2 reserved for SNMPv2c RFC 3411
3 User-Based Security Model (USM) RFC 3411
4 Transport Security Model (TSM) RFC 5591
5-255 Unassigned

Message Processing Models

Registration Procedure(s)

  • Standards Action

Reference

  • RFC 3411: An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks

Note

The SnmpMessageProcessingModel TEXTUAL-CONVENTION values managed by IANA are in the range 0 to 255, inclusive. Each value uniquely identifies a standards-track Message Processing Model of the Message Processing Subsystem within a SNMP Management Architecture.

Should this range prove insufficient in the future, an enterprise number may be obtained for the standards committee to get an additional 256 possible values.

Available Formats

Value Description Reference
0 reserved for SNMPv1 RFC 3411
1 reserved for SNMPv2c RFC 3411
2 reserved for SNMPv2u and SNMPv2* RFC 3411
3 reserved for SNMPv3 RFC 3411
4-255 Unassigned
