This chapter describes the different types of SNMP-based network management tools, called StreamView^(TM), used for network operation. It also briefly discusses using SNMP for network management.

Network Management Tools

To manage your LightStream network using local management tools, you can connect to a local console port on the switch or telnet to the network processor. You can also manage the network by using a network management station (NMS) with a network connection to the switch. The NMS must be a Sun SPARCstation. Since the LightStream network uses SNMP as its management protocol, it is also compatible with a variety of SNMP-based management systems.

The following sections give a brief description of the LightStream network tools you can use to perform network management functions.

The Command Line Interface (CLI)

The command line interface (CLI) tool is a simple line-oriented interface that you can use to perform network operations for any switch in the network through Telnet. The CLI can also be loaded and run on a Sun SPARCstation in which case the CLI converts the CLI commands you enter into SNMP messages to be sent to the LightStream switches. From the CLI, you can perform a variety of network management functions, such as network monitoring, control, and troubleshooting. The CLI does not provide a graphical user interface.

The LightStream Configurator

You configure the LightStream network using a configuration program, called the configurator. Initially, you use the configurator to create configurations for all the LightStream switches in your network. You can then use the configurator to change existing configurations or to add new ones as your network grows. The configurator features a user-friendly graphical interface that, in many cases, reduces configuration tasks to clicking a mouse button. The configurator runs on a Sun SPARCstation.

LightStream Monitor

The LightStream monitor is a graphical interface that displays the status of individual LightStream switches, cards, and ports. When you open the monitor, it displays the front of the LightStream switch with bulkheads for the cards as they appear in the actual switch.

Management Functions for Lightstream Networks

Table 5-1 lists the network management tools and documents for you to use when performing these functions.

Using SNMP For Network Management

The LightStream network uses SNMP as its management protocol and is compatible with a variety of SNMP-based management systems. The LightStream software contains an SNMP agent that interacts with your network management tools. You can manage your network with a minimal knowledge of SNMP. If you are familiar with SNMP, you can also use low-level CLI commands such as getsnmp and setsnmp to monitor and manage your LightStream network.

The SNMP agent is called the Master Management Agent (MMA) and runs on the network processor. It is the focal point for all requests, responses, and trap messages that go to and from network management software. The MMA is a MIB manager and provides access to the MIB for external users (SNMP-compatible NMSes) and internal users (the CLI within a LightStream switch). The MMA manages the LightStream MIB and provides a single interface to all data internal to the LightStream switch.

For details on the LightStream MIB, see the LightStream 2020 CLI Reference Manual
