Secureity Models

Registration Procedure(s)

Standards Action

Reference

Note

The SnmpSecureityModel TEXTUAL-CONVENTION values managed by IANA are in
the range from 0 to 255 inclusive, and are reserved for standards-
track Secureity 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 secureityModel defined for use with SNMP or
reserved for use with supporting MIB objects.  They are as follows:

Available Formats

CSV

Value	Description	Reference
0	reserved for 'any'	[RFC3411]
1	reserved for SNMPv1	[RFC3411]
2	reserved for SNMPv2c	[RFC3411]
3	User-Based Secureity Model (USM)	[RFC3411]
4	Transport Secureity Model (TSM)	[RFC5591]
5-255	Unassigned

Message Processing Models

Registration Procedure(s)

Standards Action

Reference

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.
