A typical example of SNMP in use is when one or more administrative computers, called managers, have the task of
monitoring or managing a group of hosts or devices on a computer network. Each managed system executes, at all times, a
software component called an agent which reports information via SNMP to the manager.
SNMP agents expose management data on the managed systems as variables. The protocol also permits active management
tasks, such as modifying and applying a new configuration through remote modification of these variables. The variables
accessible via SNMP are organized in hierarchies. These hierarchies, and other metadata (such as type and description of the
variable), are described by Management Information Bases (MIBs).
The device supports several public MIBs and one private MIB for the SNMP agent.
The supported MIBs are as follows:
MIB-II (RFC 1213, Include IPv6)
IF-MIB
IP-MIB
TCP-MIB
UDP-MIB
SMIv1 and SMIv2
SNMPv2-TM and SNMPv2-MIB

Scenario Application Timing
There are two application scenarios of SNMP Network Management Systems (NMS). Local NMS is in the Intranet and
manages all devices that support the SNMP protocol in the Intranet. Another one is the Remote NMS to manage devices
whose WAN interfaces are connected together by using a switch or a router with UDP forwarding. If you want to manage
