Configuring Additional File Transfer Functions

Configuring a Router as a Server

The following example a router to send a copy of the file gs7-k.9.17in Flash memory in response to a TFTP Read Request. The client router must reside on a network specified by access list 1. Thus, in the example, the any clients on network 172.16.101.0 are permitted access to the file.

Server# configure terminal

Enter configuration commands, one per line. End with CTRL/Z

Server(config)# tftp-server flash gs7-k.9.17 1

Server(config)# access-list 1 permit 172.16.101.0 0.0.0.255

Server(config)# end

Server# copy running-config startup-config

[ok]

Server#

Configuring the Client Router

Configure the client router to first load a system image from the server. As a backup, configure the client router to then load its own ROM image if the load from a server fails. To configure the client router, use the following commands beginning in privileged EXEC mode:

	Command	Purpose
Step 1
	configure terminal	Enters global configuration mode from the terminal.
Step 2
	no boot system	Removes all previous boot system statements from
		the configuration file.
Step 3
	boot system [tftp] filename [ip-address]	Specifies that the client router load a system image
		from the server.
Step 4
	boot system rom	Specifies that the client router loads its own ROM
		image if the load from a server fails.
Step 5
	config-register value	Sets the configuration register to enable the client
		router to load a system image from a network server.
Step 6
	end	Exits global configuration mode.
Step 7
	copy running-config startup-config	Saves the configuration file to your startup
		configuration.
Step 8
	reload	Reloads the router to make your changes take effect.
Step 9
		(Router reboots.)
Step 10
	show version	Verifies that the client router booted the correct image
		from the TFTP server.

Caution Using the no boot system command, as in the following example, will invalidate all other boot system commands currently in the client router system configuration. Before proceeding, determine whether the system configuration stored in the client router should first be saved (uploaded) to a TFTP file server so you have a backup copy.
