− Set: An SNMP manager performs this operation to set values of one or more objects
in the MIB of the SNMP agent of the AP.
8.1.3 SNMP protocol version
The AP is compatible with SNMP V1 and SNMP V2C and adopts the community
authentication mechanism. Community name is used to define the relationship between an
SNMP agent and an SNMP manager. If the community name contained in an SNMP packet is
rejected by a device, the packet is discarded. A community name functions as a password to
control SNMP agent access attempts of SNMP managers.
SNMP V2C is compatible with SNMP V1 and provides more functions than SNMP V1.
Compared with SNMP V1, SNMP V2C supports more operations (GetBulk and InformRequest)
and data types (such as Counter64), and provides more error codes for better distinguishing
errors.
8.1.4 MIB introduction
An MIB adopts a tree structure. The nodes of the tree indicate managed objects. A path
consisting of digits and starting from the root can be used to uniquely identify a node. This
path is calling an object identifier (OID). The following figure shows the structure of an MIB.
In the figure, the OID of A is 1.3.6.1.2.1.1, whereas the OID of B is 1.3.6.1.2.1.2.
