SNMP Interface
MIB Tables
MIB Tables
Related objects are normally grouped together to form a table. For example, the interface table
(“ifTable” “1.3.6.1.2.1.2.2”) contains information about each interface of the device. Objects in this
table are accessed by adding a dot-number to the object name or identifier to select the desired interface.
In this table the interface description object is “ifDesc” “1.3.6.1.2.1.2.2.1.2”, so the description of the
tenth interface is contained in “ifDescr.10” “1.3.6.1.2.1.2.2.1.2.10”.
