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.
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.
