Simple Network Management Protocol (SNMP)

Simple Network Management Protocol (SNMP) manages and monitors network ConnectPort LTS
devices. The SNMP architecture enables a network administrator to manage:
Nodes—servers, workstations, routers, switches, and hubs—on an IP network.
n
Network performance, such as finding and solving network problems, and planning for network
n
growth.
Digi devices support SNMP Versions 1 and 2.

About Simple Network Management Protocol (SNMP)

SNMP is a widely-used standard protocol that allows you to manage all device nodes on an IP
network, solve network problems, and improve network performance.
Most Digi devices support SNMP versions 1 and 2.
ConnectPort LTS supports SNMP versions 1, 2, and 3.
SNMP is easy to implement in extensive networks because the standard architecture allows you to
easily program new variables and drop in new devices into a network.
However, because device communication is UDP-based, the communication is not secure. If you
require secure communications with a device, use an alternate device interface. Also, SNMP does not
allow you to perform all the tasks available from the ConnectPort LTSweb or command line interfaces,
such as file management, uploading firmware, or backing up and restoring configurations. Compared
to the web or command-line interfaces, SNMP offers a limited set of management and configuration
options.

Management Information Bases (MIBs)

Accessing the SNMP interface requires a tool, such as a network management station. The
management station relies on an agent at a device to retrieve or update the information at the
device, including device configuration, status, and statistical information. This information is viewed as
a logical database, called a Management Information Base (MIB). MIB modules describe MIB variables
for a variety of device types and computer hardware and software components.
