users with limited knowledge of device programming.
Not all actions in the web interface have direct equivalents in RCI.

SNMP
Use SNMP to manage and monitor network devices. SNMP architecture allows you to:
n
Manage nodes on an IP network, including servers, workstations, routers, switches and hubs
n
Manage network performance, find and solve network problems, and plan for network growth
SNMP is easy to implement in extensive networks. You can program new variables and drop in new
devices in a network. SNMP is widely used. It is a standard interface that integrates well with network
management stations in an enterprise environment.
However, because device communication is UDP-based, the communication is not secure. If you
require more secure communications with a device, use an alternate device interface. SNMP does not
allow you to perform certain tasks 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/search/rfc_search.php
, 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. You can also display the text of the Digi enterprise
MIBs. The product page for each product on the Digi website provides a link to the Digi-provided MIBs
for that product. See
Simple Network Management Protocol (SNMP)
for a list of supported MIBs.

Supported standard MIBs
The standard MIBs supported in Digi ConnectPort X Family are as follows:
n
MIB-II (RFC 1213) This is a MIB for managing a TCP/IP network. It is an update of the original
MIB, now called MIB-I. MIB-II contains variable definitions that describe the most basic
information needed to manage a TCP/IP network. These variable definitions are organized into
several groups, such as groups for managing the system, network interfaces, address
translation, transmission media, and various protocols, including IP, ICMP, TCP, UDP, EGP, and
SNMP.
n
CHARACTER-MIB (RFC 1658).
n
RS-232-MIB (RFC 1659).
n
Digi-SMI MIB (Structure of Management Information).
