4-4 Cisco 2524 and Cisco 2525 Router User Guide
Configuring the Router
The results of the show running-config and show startup-config commands will be
different if you have made changes to the configuration but have not yet written them to
NVRAM.
To make your changes permanent, enter the copy running-config startup-config
command at the enable prompt:
Router# copy running-config startup-config
********
The router is now configured and will boot with the configuration you entered.
Using AutoInstall
The AutoInstall process is designed to configure the router automatically after connection
to your WAN. In order for AutoInstall to work properly, a Transmission Control
Protocol/Internet Protocol (TCP/IP) host on your network must be preconfigured to provide
the required configuration files. The TCP/IP host may exist anywhere on the network as
long as the following two conditions are maintained:
1 The host must be on the remote side of the router’s synchronous serial connection to the
WAN.
2 User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host
must be enabled.
This functionality is coordinated by your system administrator at the site where the TCP/IP
host is located. You should not attempt to use AutoInstall unless the required files have been
provided on the TCP/IP host. For Cisco IOS Release 11.0 and earlier releases, refer to the
publication Router Products Configuration Guide for additional information. For
Cisco IOS Release 11.1 and later releases, refer to the publication Configuration
Fundamentals Configuration Guide.
Note AutoInstall works on synchronous serial connections only. The 2-wire
switched 56-kbps DSU/CSU module operates on switched 56-kbps circuits only; therefore,
you cannot use it for AutoInstall.
