Generic and Common Textual Conventions (TCs)

Appendix B in "Guidelines for Authors and Reviewers of MIB Documents [RFC4181, BCP111]", lists an initial set of Commonly used Textual Conventions. This web page is intended to keep that list up-to-date with the most commonly used TCs. If you have any suggestions for changes or additions, pls send an email to the OPS AD maintaining this page, Benoit Claise bclaise@….

The following TCs are defined in SNMPv2-TC [RFC2579]: 


   DisplayString               OCTET STRING (SIZE (0..255))
   PhysAddress                 OCTET STRING
   MacAddress                  OCTET STRING (SIZE (6))
   TruthValue                  enumerated INTEGER
   TestAndIncr                 INTEGER (0..2147483647)
   AutonomousType              OBJECT IDENTIFIER
   VariablePointer             OBJECT IDENTIFIER
   RowPointer                  OBJECT IDENTIFIER
   RowStatus                   enumerated INTEGER
   TimeStamp                   TimeTicks
   TimeInterval                INTEGER (0..2147483647)
   DateAndTime                 OCTET STRING (SIZE (8 | 11))
   StorageType                 enumerated INTEGER
   TDomain                     OBJECT IDENTIFIER
   TAddress                    OCTET STRING (SIZE (1..255))

   Note 1.  InstancePointer is obsolete and MUST NOT be used.

   Note 2.  DisplayString does not support internationalized text.
            It MUST NOT be used for objects that are required to
            hold internationalized text (which is always the case
            if the object is intended for use by humans [RFC2277]).
            Designers SHOULD consider using SnmpAdminString,
            Utf8String, or LongUtf8String for such objects.

   Note 3.  TDomain and TAddress SHOULD NOT be used in new MIB
            modules.  The TransportDomain, TransportAddressType, and
            TransportAddress TCs (defined in TRANSPORT-ADDRESS-MIB
            [RFC3419]) SHOULD be used instead.

   InetPortNumber              Unsigned32 (0..65535)
   InetAutonomousSystemNumber  Unsigned32
   InetScopeType               enumerated INTEGER

   PerfCurrentCount            Gauge32
   PerfIntervalCount           Gauge32
   PerfTotalCount              Gauge32
