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 [IMG] CSV Value Description Reference 0 reserved for 'any' [RFC3411] 1 reserved for SNMPv1 [RFC3411] 2 reserved for SNMPv2c [RFC3411] 3 User-Based Security Model (USM) [RFC3411] 4 Transport Security Model (TSM) [RFC5591] 5-255 Unassigned Message Processing Models Registration Procedure(s) Standards Action Reference [RFC3411] 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.
