Introduction
Standard MIBs supported
The standard MIBs supported in Digi Cellular Family devices are:
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.
CHARACTER-MIB (RFC 1658)
RS-232-MIB (RFC 1659).
Digi enterprise MIBs supported
In addition to the standard MIBs, Digi devices use several Digi enterprise MIBs,
including:
DIGI-DEVICE-INFO.mib: for handling device information. This MIB gives
access to elements like the firmware revision, device name, IP network
information, memory, and CPU statistics.
DIGI-SERIAL-ALARM-TRAPS.mib: for handling alarms sent as SNMP traps.
Additional SNMP resources
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 www.rfceditor.org, 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 208.
