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.
