SNMP Versions and
Supported MIB
to report the events whenever the device encounters any abnormalities such as
new device found and restart.
To uniquely identify the management variables of a device in SNMP messages,
SNMP adopts the hierarchical naming scheme to identify the managed objects. It
is like a tree. A tree node represents a managed object, as shown in the figure
below. Thus the object can be identified with the unique path starting from the
root.

The MIB (Management Information Base) is used to describe the hierarchical
architecture of the tree and it is the set defined by the standard variables of the
monitored network device. In the above figure, the managed object B can be
uniquely specified by a string of numbers {1.2.1.1}. The number string is the
Object Identifier of the managed object.
The current SNMP Agent of the Switch supports SNMP V1, V2C and V3. The MIBs
supported are listed in the following table.
