2016-05-03 Standards Action 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: 0 reserved for 'any' 1 reserved for SNMPv1 2 reserved for SNMPv2c 3 User-Based Security Model (USM) 4 Transport Security Model (TSM) 5-255 Unassigned Standards Action 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. 0 reserved for SNMPv1 1 reserved for SNMPv2c 2 reserved for SNMPv2u and SNMPv2* 3 reserved for SNMPv3 4-255 Unassigned Unassigned 1-127 Specification Required 128-255 Enterprise-specific IANA does not assign 0 Reserved 1 IPv4 address 2 IPv6 address 3 MAC address 4 administratively assigned text 5 administratively assigned octets 6 local engine 7-127 Unassigned 128-255 Enterprise-specific Standards Action IETF standard protocols for SNMPv3 authentication and privacy The MIB module defined in defines this OBJECT-IDENTITY as registration points. 0 Reserved 1 usmNoAuthProtocol - no authentication 2 usmHMACMD5AuthProtocol - HMAC-MD5-96 3 usmHMACSHAAuthProtocol - HMAC-SHA-96 4 usmHMAC128SHA224AuthProtocol 5 usmHMAC192SHA256AuthProtocol 6 usmHMAC256SHA384AuthProtocol 7 usmHMAC384SHA512AuthProtocol Standards Action IETF standard protocols for SNMPv3 authentication and privacy The MIB module defined in defines this OBJECT-IDENTITY as registration points. 0 Reserved 1 usmNoPrivProtocol - no privacy 2 usmDESPrivProtocol - CBC-DES 3 Reserved 4 usmAesCfb128Protocol - AES-CFB-128 Specification Required Unassigned Each domain is assigned a MIB-defined OID under snmpDomains. udp snmpUDPDomain clns snmpCLNSDomain cons snmpCONSDomain ddp snmpDDPDomain ipx snmpIPXDomain prxy rfc1157Domain ssh snmpSSHDomain tls snmpTLSTCPDomain dtls snmpDTLSUDPDomain
