How To Use the Network Control Language (NCL) Commands To Manage a Router

Introducing NCL

Introducing NCL

This chapter describes how to use the Network Control Language Interpreter (NCL). NCL is an easy-to-access command-line control interface with capabilities such as the following.

Restart (“boot”) the router.

Set two levels of passwords to control access to the router through the console and via Telnet.

Set the date and time kept by the router.

Perform link-layer and network-layer tests of remote nodes on the extended network.

Use an upper-layer IP router service to make a virtual terminal connection to a remote node on the extended network.

Enable or disable specific software entities and services within the router, such as routing services, and logical network connections, such as circuits.

Use the IP router and the SNMP agent to access application-specific bridging and routing tables from a local or remote router.

Access the router’s management information base (MIB) for detailed information about router operations. Reset MIB variables.

Use the IP router and the Simple Network Management Protocol (SNMP) agent to access either the standard Internet MIB (as defined in Internet RFC 1156) or the vendor-specific MIB of any remote node with a standard SNMP/MIB implementation.

Download the router’s configuration or operating code from a remote computer or router, or store its configuration or operating code on a remote computer or router.

Display the router’s current configuration.

Direct the output of any display command to a printer or a file rather than to the console. This file can be on the local PC used as the console, or on a remote computer or router.

Access the configuration editor, the event log, statistics screens, or quick configuration without returning to the Main menu.
