Snmp - D-Link DES-3250TG User Manual

SNMP

The Simple Network Management Protocol (SNMP) is an OSI
layer 7 (the application layer) protocol for remotely monitoring
and configuring network devices. SNMP enables network
management stations to read and modify the settings of
gateways, routers, switches, and other network devices. SNMP
can be used to perform many of the same functions as a
directly connected console, or can be used within an integrated
network management software package such as DView or HP
OpenView.
SNMP performs the following functions:
•
Sending and receiving SNMP packets through the IP
protocol.
•
Collecting information about the status and current
configuration of network devices.
•
Modifying the configuration of network devices.
The DES-3250TG has a software program called an 'agent' that
processes SNMP requests, but the user program that makes
the requests and collects the responses runs on a management
station (a designated computer on the network). The SNMP
agent and the user program both use the UDP/IP protocol to
exchange packets.
Authentication
The authentication protocol ensures that both the router SNMP
agent and the remote user SNMP application program discard
packets from unauthorized
accomplished using 'community strings', which function like
passwords. The remote user SNMP application and the router
SNMP must use the same community string.
