Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring
network devices. The SNMP architecture enables a network administrator to manage nodes--
servers, workstations, routers, switches, hubs, etc.--on an IP network; manage network
performance, find and solve network problems, and plan for network growth. Digi devices support
SNMP Versions 1 and 2.
SNMP is easy to implement in extensive networks. Programming new variables and “dropping in”
new devices in a network are easy. SNMP is widely used. It is a standard interface that integrates
well with network management stations in an enterprise environment. While its capabilities are
limited to device monitoring and display of statistics in Digi devices, read/write capabilities are
expected to be added to Digi devices in future releases.
However, because device communication is UDP-based, the communication is not secure. If more
secure communications with a device are required, use an alternate device interface. SNMP does
not allow for certain task that can be performed from the web interface, such as file management,
uploading firmware, or backing up and restoring configurations. Compared to the web or
command-line interfaces, SNMP is limited in its ability to set specific parameters, such as set port
profile, is not possible.
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.
A variety of resources about SNMP are available, including reference books, overviews, and other
files on the Internet. For an overview of the SNMP interface and the components of MIB-II, go to
http://www.rfc-editor.org/rfcsearch.html, and search for MIB-II. From the results, locate the text
file describing the SNMP interface, titled Management Information Base for Network
Management of TCP/IP-based internets: MIB-II. The text of the Digi enterprise MIBs can also be
displayed.
For additional discussion of using SNMP as a device monitoring interface, see "Monitoring
Capabilities from SNMP" on page 209.
