Abstract

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing DS1 Interfaces -- including both T1 and E1 (a.k.a., CEPT 2 Mbit/s) links.

Abstract

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

for use with network management protocols in TCP/IP-based internets.

In particular, it defines objects for managing DS1 Interfaces --

including both T1 and E1 (a.k.a., CEPT 2 Mbit/s) links.

This document entirely replaces RFC 1232, which contains a

fundamental error: many objects are encoded as Counters that must be

encoded as INTEGERs or Gauges. The magnitude of the change required

is sufficient that virtually every object changed. Therefore, the

MIB documented in RFC 1232 should not be implemented.
