2.1. The System Group

2.1. The System Group

-- the System group
--
-- a collection of objects common to all managed systems.

system   OBJECT IDENTIFIER ::= { mib-2 1 }

sysDescr OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..255))
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
            "A 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."
    ::= { system 1 }

sysObjectID OBJECT-TYPE
    SYNTAX      OBJECT IDENTIFIER
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
            "The 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'."
    ::= { system 2 }

sysUpTime OBJECT-TYPE
    SYNTAX      TimeTicks
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
            "The time (in hundredths of a second) since the network
            management portion of the system was last re-initialized."
    ::= { system 3 }

sysContact OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..255))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "The 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."
    ::= { system 4 }

sysName OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..255))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "An 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."
    ::= { system 5 }

sysLocation OBJECT-TYPE
    SYNTAX      DisplayString (SIZE (0..255))
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "The physical location of this node (e.g., `telephone
            closet, 3rd floor').  If the location is unknown, the value
            is the zero-length string."
    ::= { system 6 }

sysServices OBJECT-TYPE
    SYNTAX      INTEGER (0..127)
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
            "A value which indicates the set of services that this
            entity may potentially offers.  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."
    ::= { system 7 }

    STATUS     current
    DESCRIPTION
            "An authoritative identification of a capabilities statement
