Mib Listing - D-Link D-View 5.1 User Manual

D-View 5.1 User's Guide
When the management console needs to modify the value of a particular MIB object, it
sends a SET request to the device SNMP agent and the numerical representation of the
target MIB object followed by the new value.
For example, if the management console wants to assign a new name to a device, it
sends a SET request to the device SNMP agent followed by the numerical
representation of the sysName MIB object, which is 1.3.6.1.2.1.1.5.0. This is then
followed by the corresponding value of the new name. The agent uses the provided
values to search for the specified MIB object in the device and then sets its value
accordingly.

MIB Listing

Normally, related MIB objects are listed in a group called Object Group. Each group
contains an Object ID, Syntax, Access Right, Status, and Description. The following
describes each term:
♦ Object ID – This is the numeric representation of the MIB object in the tree.
♦ Syntax – This specifies the object type (that is, integer, string, counter, etc.).
♦ Access Right – This specifies the access right of the MIB object.
♦ Status – This provides information about the status of the MIB object. It can be
mandatory, optional, obsolete, or deprecated. Mandatory means that the object
must be implemented (standard MIBs always have this status), optional means
that the object may be implemented, obsolete indicates the object is no longer
supported, and deprecated indicates the object is soon to be phased out.
♦ Description – This usually describes the function of the MIB object.
Here is a sample of a standard MIB-II listing:
Object Group: system
MIB sysUpTime
OBJECT-ID (1.3.6.1.2.1.1.3.0)
SYNTAX TimeTicks
ACCESS read-only
STATUS mandatory
DESCRIPTION The time (in hundredths of a second) since the network management
portion of the system was last re-initialized.
