SNMPv2-MIB
AI MIB Summary
The SNMPv2-MIB defines the core system-level objects and standard counters for SNMP entities, enabling the monitoring of device uptime, system contact, location, and interface statistics across all compliant network hardware and software. It serves as the foundational data structure for retrieving basic operational metrics such as system description, OID tree traversal, and standard counter values required for network management protocols.

system OBJECT IDENTIFIER .1.3.6.1.2.1.1 |
sysDescrA textual description of the entity. This value should include the full name and version identification of the system's hardware type, software operating-system, and networking software.ro DisplayString .1.3.6.1.2.1.1.1 |
sysObjectIDThe vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determining `what kind of box' is being managed. For example, if vendor `Flintstones, Inc.' was assigned the subtree 1.3.6.1.4.1.424242, it could assign the identifier 1.3.6.1.4.1.424242.1.1 to its `Fred Router'.ro OBJECT IDENTIFIER .1.3.6.1.2.1.1.2 |
sysUpTimeThe time (in hundredths of a second) since the network management portion of the system was last re-initialized.ro TimeTicks (SNMPv2-SMI) .1.3.6.1.2.1.1.3 |
sysContactThe textual identification of the contact person for this managed node, together with information on how to contact this person. If no contact information is known, the value is the zero-length string.rw DisplayString .1.3.6.1.2.1.1.4 |
sysNameAn administratively-assigned name for this managed node. By convention, this is the node's fully-qualified domain name. If the name is unknown, the value is the zero-length string.rw DisplayString .1.3.6.1.2.1.1.5 |
sysLocationThe physical location of this node (e.g., 'telephone closet, 3rd floor'). If the location is unknown, the value is the zero-length string.rw DisplayString .1.3.6.1.2.1.1.6 |
sysServicesA value which indicates the set of services that this entity may potentially offer. The value is a sum. This sum initially takes the value zero. Then, for each layer, L, in the range 1 through 7, that this node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node which performs only routing functions would have a value of 4 (2^(3-1)). In contrast, a node which is a host offering application services would have a value of 72 (2^(4-1) + 2^(7-1)). Note that in the context of the Internet suite of protocols, values should be calculated accordingly: layer functionality 1 physical (e.g., repeaters) 2 datalink/subnetwork (e.g., bridges) 3 internet (e.g., supports the IP) 4 end-to-end (e.g., supports the TCP) 7 applications (e.g., supports the SMTP) For systems including OSI protocols, layers 5 and 6 may also be counted.ro INTEGER .1.3.6.1.2.1.1.7 |
sysORLastChangeThe value of sysUpTime at the time of the most recent change in state or value of any instance of sysORID.ro TimeStamp (SNMPv2-TC) .1.3.6.1.2.1.1.8 |
sysORTableThe (conceptual) table listing the capabilities of the local SNMP application acting as a command responder with respect to various MIB modules. SNMP entities having dynamically-configurable support of MIB modules will have a dynamically-varying number of conceptual rows. SEQUENCE OF SysOREntry .1.3.6.1.2.1.1.9 |
sysOREntryAn entry (conceptual row) in the sysORTable. SysOREntry .1.3.6.1.2.1.1.9.1 |
sysORIndexThe auxiliary variable used for identifying instances of the columnar objects in the sysORTable. INTEGER .1.3.6.1.2.1.1.9.1.1 |
sysORIDAn authoritative identification of a capabilities statement with respect to various MIB modules supported by the local SNMP application acting as a command responder.ro OBJECT IDENTIFIER .1.3.6.1.2.1.1.9.1.2 |
sysORDescrA textual description of the capabilities identified by the corresponding instance of sysORID.ro DisplayString (SNMPv2-TC) .1.3.6.1.2.1.1.9.1.3 |
sysORUpTimeThe value of sysUpTime at the time this conceptual row was last instantiated.ro TimeStamp (SNMPv2-TC) .1.3.6.1.2.1.1.9.1.4 |
snmp OBJECT IDENTIFIER .1.3.6.1.2.1.11 |
snmpInPktsThe total number of messages delivered to the SNMP entity from the transport service.ro Counter32 .1.3.6.1.2.1.11.1 |
snmpOutPktsThe total number of SNMP Messages which were passed from the SNMP protocol entity to the transport service.roobsolete Counter32 .1.3.6.1.2.1.11.2 |
snmpInBadVersionsThe total number of SNMP messages which were delivered to the SNMP entity and were for an unsupported SNMP version.ro Counter32 .1.3.6.1.2.1.11.3 |
snmpInBadCommunityNamesThe total number of community-based SNMP messages (for example, SNMPv1) delivered to the SNMP entity which used an SNMP community name not known to said entity. Also, implementations which authenticate community-based SNMP messages using check(s) in addition to matching the community name (for example, by also checking whether the message originated from a transport address allowed to use a specified community name) MAY include in this value the number of messages which failed the additional check(s). It is strongly RECOMMENDED that the documentation for any security model which is used to authenticate community-based SNMP messages specify the precise conditions that contribute to this value.ro Counter32 .1.3.6.1.2.1.11.4 |
snmpInBadCommunityUsesThe total number of community-based SNMP messages (for example, SNMPv1) delivered to the SNMP entity which represented an SNMP operation that was not allowed for the SNMP community named in the message. The precise conditions under which this counter is incremented (if at all) depend on how the SNMP entity implements its access control mechanism and how its applications interact with that access control mechanism. It is strongly RECOMMENDED that the documentation for any access control mechanism which is used to control access to and visibility of MIB instrumentation specify the precise conditions that contribute to this value.ro Counter32 .1.3.6.1.2.1.11.5 |

snmpEnableAuthenTrapsIndicates whether the SNMP entity is permitted to generate authenticationFailure traps. The value of this object overrides any configuration information; as such, it provides a means whereby all authenticationFailure traps may be disabled. Note that it is strongly recommended that this object be stored in non-volatile memory so that it remains constant across re-initializations of the network management system.rw Enumeration .1.3.6.1.2.1.11.30 |
snmpSilentDropsThe total number of Confirmed Class PDUs (such as GetRequest-PDUs, GetNextRequest-PDUs, GetBulkRequest-PDUs, SetRequest-PDUs, and InformRequest-PDUs) delivered to the SNMP entity which were silently dropped because the size of a reply containing an alternate Response Class PDU (such as a Response-PDU) with an empty variable-bindings field was greater than either a local constraint or the maximum message size associated with the originator of the request.ro Counter32 .1.3.6.1.2.1.11.31 |
snmpProxyDropsThe total number of Confirmed Class PDUs (such as GetRequest-PDUs, GetNextRequest-PDUs, GetBulkRequest-PDUs, SetRequest-PDUs, and InformRequest-PDUs) delivered to the SNMP entity which were silently dropped because the transmission of the (possibly translated) message to a proxy target failed in a manner (other than a time-out) such that no Response Class PDU (such as a Response-PDU) could be returned.ro Counter32 .1.3.6.1.2.1.11.32 |
