SNMP Version 2c: SNMP v2c also uses Community Name Authentication. It is compat-
ible with SNMP v1 and expands the functions of SNMP v1.
SNMP Version 3: Based on SNMP v1 and SNMP v2c, SNMP v3 greatly enhances the
security and manageability of SNMP. It adopts VACM (View-Based Access Control
Model) and USM (User-Based Security Model) Authentication. You can confi gure
the Authentication and Encryption functions. The Authentication function is used to
limit the access of an illegal user by authenticating the sender of SNMP packets. The
Encryption function is used to encrypt the SNMP packets transmitted between the
SNMP Management Station and SNMP Agent. The combination of Authentication
and Encryption creates more reliable communications between SNMP Management
stations and SNMP Agents.
MIB Introduction
To uniquely identify the Management Objects of a device in SNMP messages, SNMP
adopts a hierarchical architecture to identify the Managed Objects. It uses a tree format
with each tree node representing a Managed Object, as shown in the following fi gure
below. This allows Objects to be identifi ed within the unique path starting from the
root and indentifi ed by a string of numbers. The number string is the Object Identifi er
of the Managed Object. In the following fi gure, the OID of Managed Object B is {1.2.1.1}.
While the OID of Managed Object A is {1.2.1.1.5}.
