System Object

The following table describes the standard SNMP Get support for the system group which is a collection of objects common to all managed systems.

MIB Object Object ID: 1.3.6.1.2.1.1 + Description
sysDescr .1 Textual description of the entity. This value includes the full name and version identification of the system's hardware type, software operating-system, and networking software.
sysObjectID .2 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 1.3.6.1.4.1.4242, it could assign the identifier 1.3.6.1.4.1.4242.1.1 to its Fred Router.
sysUpTime .3 Time (in hundredths of a second) since the network management portion of the system was last re-initialized.
sysContact .4 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.
sysName .5 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.
sysLocation .6 Physical location of this node (for example, telephone closet, 3rd floor). If the location is unknown, the value is the zero-length string.
sysServices .7 Value which indicates the set of services that this entity may potentially offer. The value is a sum which 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)). See the following table for how this value is calculated.
sysORLastChange .8 Value of sysUpTime at the time of the most recent change in state or value of any instance of sysORID.
layer functionality
1 physical (for example, repeaters)
2 datalink/subnetwork (for example, bridges)
3 internet (for example, supports IP)
4 end-to-end (for example, supports TCP)
7 applications (for example., supports SMTP)
For systems including OSI protocols, layers 5 and 6 may also be counted.

Object Resource Information Object

The following table describes the standard SNMP Get support for the object resource information which is a collection of objects which describe the SNMPv2 entity's (statistically and dynamically configurable) support of various MIB modules.

MIB Object Object ID: 1.3.6.1.2.1.1.9 + Description
sysORID .2 Authoritative identification of a capabilities statement with respect to various MIB modules supported by the local SNMPv2 entity acting in an agent role
sysORDescr .3 Textual description of the capabilities identified by the corresponding instance of sysORID.
sysORUpTime .4 Value of sysUpTime at the time this conceptual row was last instantiated.
