(AMI/B8ZS, D4/ESF), and to enable detection of standard D4/ESF inband loop codes by the integral CSUs. In the remote software control mode, you can use SNMP, CLI, or GUI management terminals.

1.7.2 SNMP Management

The Access Bank II SNMP:

•Supports Simple Network Management Protocol version 2 (SNMPv2) through its Ether- net 10Base-T port.

•Complies with RFC standards for for SNMPv2, Ethernet, Internet, TCP/IP, and MIB-II network management, and T1 and RS-232 interfaces.

•Has built-in SNMPv2 Agent software providing network statistics, information retrieval and update, trap thresholds, and automatic transmission of trap data to Network Manage- ment Stations.

1.7.2.1Local and Remote SNMP Management

The Access Bank II SNMP provides SNMP management through its Ethernet 10Base-T port. Remote SNMP management is possible over either of the T1 lines within a V.35 user data segment, as shown in Figure 1-1.

1.7.2.2 SNMP Overview

SNMP is a complete, but simple, mechanism for network management. It works by exchanging infor- mation between a Manager and an Agent. In this case, the Agent is inside the Access Bank II/SNMP. The Manager is a Network Management Station (NMS), which is a computer with SNMP manage- ment software such as HP OpenView® or Sun NetManager®.

The Agent stores the information in a Management Information Base (MIB), which contains items such as the current status of the network interface, performance statistics, and alarms.

In general, SNMP is not concerned with controlling every feature of the many different network objects. However, SNMP is flexible enough that it can support a wide variety of private enterprise objects with predefined MIB data structures. The Access Bank II/SNMP uses the Bellcore® standard MIB for T1 interfaces.

Manager operations include simple “get” and “set” commands to retrieve and update MIB data in the
