SNMP MIB Objects

Overview
This appendix describes the Management Information Base (MIB) objects that
are supported by the DSU/CSU.
The DSU/CSU supports the following MIBs:
H MIB II – Defines the general objects for use in Transmission Control
Protocol/Internet Protocol (TCP/IP) internets and provides general
information about the DSU/CSU.
H DS1/E1 MIB – Defines objects for managing DS1 interfaces and supports the
network and DTE Drop/Insert (DSX-1) interfaces on the DSU/CSU.
H RS-232-like MIB – Defines objects for managing RS-232-type interfaces and
supports synchronous data ports (PORTs 1– 2) and management
communication (COM) port on the DSU/CSU.
H Generic-Interface MIB Extension – An extension to MIB II that defines
additional objects for control of generic interfaces in MIB II. It supports control
of tests on the DTE Drop/Insert (DSX-1) and synchronous data interfaces
that are not supported by other MIBs.
H Enterprise MIB – Defines objects unique to devices like the Model 3162.
MIB II (RFC 1213)
The objects defined by MIB II are organized into 10 different groups. The
DSU/CSU implements only those groups where the semantics of the group are
applicable to the implementation of a DSU/CSU. The MIB II object groups
supported or not supported by the 3100 Series devices are as follows:
System
Group
Supported.
Interface
Group
Supported for the network interface, the DTE Drop/Insert
(DSX-1) interface, the synchronous data ports, and the COM
port. Interface statistics (counters) apply to the COM port
when it is defined as the SNMP management link.
