Chapter 1. Introduction

This header information contains a virtual circuit address known as a DLCI (data link connection identifier). The header informa- tion also contains bits used for network congestion control.

Frame relay virtual circuits may be defined as permanent (PVC) or switched (SVC). PVCs have the same DLCI for a given path each time a user protocol session is established. The network service provider assigns these DLCIs at subscription time. SVCs, on the other hand, have DLCIs dynamically assigned each time a user protocol session is established. The CPE equipment must request a call and the DLCI is assigned by the network switching equipment. This DLCI is valid until the call is disconnected and may be assigned a different value each time a call is requested.

SNMP MANAGEMENT

SNMP management capability is provided in-band with support for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), and ADTRAN Enterprise MIB. MIB files are available from ADTRAN in the support section of the ADTRAN Web page at www.adtran.com. TELNET capability is also supported. For non-TCP/IP environments, VT 100 and front panel operation are supported.

The IQ Probe's embedded SNMP feature allows the unit to be accessed and controlled by a network manager in-band at the DTE or DCE interface, out-of-band at the control port via SLIP or async PPP, or using a LAN connection.

The term SNMP broadly refers to the message protocols used to exchange information between the network and the managed devices, as well as to the structure of network management data bases. The three basic components of SNMP follow:

Network Manager

Control program that collects, controls, and presents data pertinent to the operation or management of the network devices. It resides on a network management station.
