Abstract

This memo defines a portion of the Management Information Base (MIB)

for use with network management protocols in the Internet community.

In particular, it describes objects used for managing DS1, E1, DS2

and E2 interfaces. This document is a companion document with

Definitions of Managed Objects for the DS0 (RFC 2494 [30]), DS3/E3

(RFC 2496 [28]), and the work in progress, SONET/SDH Interface Types.

This memo specifies a MIB module in a manner that is both compliant

to the SNMPv2 SMI, and semantically identical to the peer SNMPv1

definitions.
