Management Tools
Management Tools
You can use the following methods to manage an LS2020 network:
•
LS2020 network management. Use the LS2020 StreamView network management application
to perform most management functions. You can, however, use the CLI on one of the network
processors (NPs) or on a Sun SPARCstation to perform some management tasks, if the
configurator or network management system (NMS) is unavailable. The CLI is also a monitoring
tool, but it is not graphical.
•
Network management system. Use an external, SNMP-compatible NMS.
StreamView
The LS2020 self-management tools include the StreamView network management applications. These
applications provide configuration, monitoring, and topology mapping of the LS2020 network. The
following sections give a brief description of these tools.
LS2020 Configurator
The LS2020 configurator is a user-friendly graphical interface that reduces configuration tasks to the simple
click of a mouse button. As network administrator you can use the LS2020 configurator to manage a network
of LS2020 multiservice ATM switches. For more information on the configurator, see the LightStream 2020
Configuration Guide. If the configurator is unavailable to you, you can use the CLI commands in this
document to perform many management tasks.
LS2020 Monitor
The LS2020 monitor provides graphical displays of individual LS2020 systems, cards, and ports. In
most instances you will want to use it to monitor the network. However, if the monitor is unavailable
to you, you can use the CLI commands in this document to perform many monitoring tasks. For
more information on the LS2020 monitor, see the Monitoring a LightStream 2020 Switch chapter.
LS2020 Topology Map
The LS2020 topology map provides a graphical display of the physical topology of an LS2020
network. You can modify the LS2020 map by moving nodes, changing node or trunk labels,
grouping nodes into submaps, or deleting nodes or trunks. For more information on the LS2020
topology manager, see the Monitoring a LightStream 2020 Switch chapter.
Command Line Interface
The CLI is a simple, line-based interface that runs on an LS2020 switch or a Sun SPARCstation. You
can access the CLI by connecting a terminal to the console port on the console/modem assembly on
an LS2020 switch, by using Telnet to access the NP, or by running the CLI on a Sun SPARCstation.
You can use the CLI to change and display the settings of configuration attributes on a local switch.
It also enables you to make those changes in the NP’s run-time memory only or to run-time memory
and the switch’s hard disk. For more information on the CLI, see the Command Line Interface
chapter.
