Security Models

Registration Procedure(s)

             Standards Action


Reference
        [RFC 3411]

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:

4     Transport Security Model (TSM)  [RFC 5591]

Message Processing Models

Registration Procedure(s)

             Standards Action


Reference
        [RFC 3411]

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.
