Chapter 5 SNMP Agent
5.1 Summary
SNMP is a network management standard based on TCP/IP protocol and is a
standard protocol for managing network nodes (such as servers, workstations,
routers, switches, etc.) in IP networks.SNMP can enable network administrators to
improve network management efficiency, timely discover and solve network
problems and plan network growth.The network administrator can also receive the
notification message of network node and the alarm event report through SNMP to
learn the problems of the network.
The communication string contains two main types of commands: the GET
command, the SET command.The GET command reads data from the device, which
is usually an operational parameter, such as the connection state, interface name,
and so on.
The most common default communication strings are public (read only) and private
(read/write), along with many vendor private default communication strings.Almost
all network devices running SNMP can find some form of default communication
string.
This device only supports using the GET command from the security aspect, and
only supports the use of public communication strings.
