CHAPTER 2

TCP/IP MIB-II

The ELS10-26 supports the TCP/IP MIB-II, as defined by

Management Information Base for Network Management of TCP/
IP-based Internets MIB-II

, RFC 1213 (K. McCloghrie, editor), dated

March 1991. The MIB is divided into groups of parameters. The
individual groups are described in the subsections below. You may
want to refer to the actual TCP/IP MIB, since this document
paraphrases the standard MIB in order to provide ELS10-26-related
descriptions.

Note:

The access types of some of the TCP/IP MIB parameters have been
extended from Read-Only to Read-Write. However, unless
otherwise indicated, the access type of all parameters is as indicated
in the standard MIB.

The MIB tree prefix for reaching the TCP/IP MIB-II is:

1.3.6.1.2.1.

2.1 SYSTEM GROUP

system

{mib-2 1}

The TCP/IP System Group parameters are described below.

sysDescr

{system 1}

DisplayString Read-Only

A textual description of the ELS10-26 is Cabletron “moduleName”
Rev “FirmwareRevision” “LinkTimeandDate” i.e., Cabletron
ELS10-26 Rev xx:xx:xx 03/04/97--11:30:25

sysObjectID

{system 2}

Object Identifier Read-Only

The identifier of the variable used to identify the type of entity.
Cabletron’s MIB sysID parameter will have a value that indicates
that it is a bridge. So sysObjectID contains the object identifier of
