SNMP Management Capabilities
The DSU/CSU supports SNMP Version 1, and has the capability of being
managed by any industry-standard SNMP manager and accessed using SNMP
protocol by external SNMP managers.

Management Information Base (MIB) Support

The following MIBs are supported:
MIB II (RFC 1213 and RFC 1573) – Defines the general objects for use with
a network management protocol in TCP/IP internets and provides general
information about the DSU/CSU. MIB II is backward-compatible with MIB I.
Ethernet-like MIB (RFC 1643) – Defines objects for managing Ethernet-like
interfaces (e.g., 10BaseT).
RS-232-Like MIB (RFC 1659) – Defines objects for managing RS-232-type
interfaces and supports the V.35 synchronous data port on the DSU/CSU.
Enterprise MIB – Supports configuration, status, statistics, and tests on the
DS1 network interface.
DS1/E1 MIB (RFC1406) – Defines objects for managing DS1 interfaces and
supports the network interface on the DSU/CSU. DS1 Near End Group and
DS1 Fractional Group are supported.
Generic-Interface Extension MIB (RFC 1229) (Generic Interface Test
table only) – Provides extensions to the generic interface group defined in
MIB II.
