Carrier Access SNMP manual Local and Remote Snmp Management, Snmp Overview

14.3 SNMP Management

The Access Bank II SNMP provides:

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

•Application Support for Simple Network Management Protocol (SNMP) and Telnet, per RFC 1902 through 1907. Management Information Base (MIB), per RFC 1573.

•Transport Support for Transport Control Protocol (TCP) and User Datagram Protocol (UDP), per RFC 1213.

•Internet Support for Internet Protocol (IP) version 4, Internet Control Message Protocol (ICMP), Address Resolution Protocol (ARP), and Reverse ARP (RARP), per RFC 1213.

•Managed Object Support for T1 interfaces, per RFC 1406. Serial RS-232 and V.35 inter- faces for SNMPv2, per RFC 1659.

14.3.1Local 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 14-1.

14.3.2 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
