Architecture

Figure E-1 shows how the Remote NMCS attaches to an external interface such as Telnet, and processes basic text based commands to
the CiM database manager. The database manager is responsible for resolving GET and SET actions to Local and Remote objects.

Command Set Introduction

The following sections outline the basic command set supported in this version of the CIM NMCS protocol.
E.4.1

Telnet Interface

Telnet interface into the NMCS system must be on port 7023, which has been reserved for this protocol by the IANA.
The login process requires a name and password, which are defined by the systems administrator of the controlling equipment. This name and
password is usually associated to the name and password of an administrator account.
E.4.2

Basic Protocol

All bytes within a command are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return (cr) and Line
Feed (lf) characters are considered printable.
