Configuring Additional File Transfer Functions

Configuring a Router as a Server

Caution For full functionality, the software image sent to the client must be the same type as the ROM software installed on the client router. For example, if the server has X.25 software, and the client does not have X.25 software in ROM, the client will not have X.25 capabilities after booting from the server’s image in Flash memory.

Configuring the Server

To specify TFTP server operation, use the following commands in configuration mode:

	Command	Purpose
Step 1
	configure terminal	Enters global configuration mode from the terminal.
Step 2
	tftp-server flash [partition-number:]filename1	Specifies the system image to send in response to
	[alias filename2] [access-list-number]	Read Requests. You can enter multiple lines to
	or	specify multiple images.
	tftp-server flash device:filename (Cisco 7000 family
	only)
	or
	tftp-server flash
	[device:][partition-number:]filename
	(Cisco 1600 series and Cisco 3600 series only)
	or
	tftp-server rom alias filename1 [access-list-number]
Step 3
	end	Exits configuration mode.
Step 4
	copy running-config startup-config	Saves the configuration file to your startup
		configuration.

The TFTP session can sometimes fail. TFTP generates the following special characters to help you determine why a TFTP session fails:

•An “E” character indicates that the TFTP server received an erroneous packet.

•An “O” character indicates that the TFTP server received an out-of-sequence packet.

•A period (.) indicates a timeout.

For diagnosing any undue delay in the transfer, the output is useful. For troubleshooting procedures, refer to the Internetwork Troubleshooting Guide publication.

In the following example, the system can use TFTP to send copies of the Flash memory file version-10.3in response to a TFTP Read Request for that file. The requesting host is checked against access list 22.

tftp-server flash version-10.3 22

In the following example, the system can use TFTP to send a copy of the ROM image gs3-k.101in response to a TFTP Read Request for the gs3-k.101file:

tftp-server rom alias gs3-k.101
