RFC1213-MIB (MIB-II)
Revisions
The following changes have been applied:
• The enumerations unknown(4) and dormant(5) have been added to ifOperStatus to reflect a change
to the ifTable introduced in RFC 1573.
• The SYNTAX of ifType has been changed to IANAifType, to reflect the change to the ifTable
introduced in RFC1573.
Definitions
The following definitions are imported for MIB-II:
• mgmt, NetworkAddress, IpAddress, Counter, Gauge, TimeTicks
• From RFC1155-SMI—OBJECT-TYPE
• From RFC-1212—TEXTUAL-CONVENTION
• From SNMPv2-TC—IANAifType
• From IANAifType-MIB;
Object Identifiers
This MIB module uses the extended OBJECT-TYPE macro as defined in [14]. MIB-II (same prefix as
MIB-I) mib-2 OBJECT IDENTIFIER ::= { mgmt 1 }.
Textual Conventions
DisplayString ::= OCTET STRING
This data type is used to model textual information taken from the NVT ASCII character set. By
convention, objects with this syntax are declared as having SIZE (0..255).
PhysAddress ::= OCTET STRING
This data type is used to model media addresses. For many types of media, this will be in a binary
representation. For example, an ethernet address would be represented as a string of 6 octets.
Groups in MIB-II
system OBJECT IDENTIFIER ::= { mib-2 1 }
interfaces OBJECT IDENTIFIER ::= { mib-2 2 }
at OBJECT IDENTIFIER ::= { mib-2 3 }
ip OBJECT IDENTIFIER ::= { mib-2 4 }
icmp OBJECT IDENTIFIER ::= { mib-2 5 }
tcp OBJECT IDENTIFIER ::= { mib-2 6 }
udp OBJECT IDENTIFIER ::= { mib-2 7 }
