TFTP

The IOS images and configuration files can be transferred to and from the routers by using the
TFTP protocol.

The write network or copy running-config tftp command saves the configuration file on a
TFTP server. These commands perform the same function. You must then enter the IP address
of the TFTP server and the filename, as shown in Example 3-9. The configure network or copy
tftp running-config command copies the configuration file from the TFTP server. The file is
copied into active RAM memory.

Example 3-9

The copy tftp running-config Command

R2#copy tftp running-config
Address or name of remote host []? 1.1.1.1
Source filename []? router-config1
Destination filename [running-config]?

IOS image files can also be transferred to and from a TFTP server. You must enter the IP address
and filenames when using the copy flash tftp command, as shown in Example 3-10. The copy
flash tftp command copies from the flash file system to the TFTP server. The copy tftp flash
command copies the IOS image from the TFTP server and places it in the flash file system.

Example 3-10 copy Commands Used to Copy IOS from Flash to the TFTP Server or Vice Versa

r4#copy flash tftp
Source filename []? mc3810
Address or name of remote host []? 1.1.1.1
Destination filename [mc3810]?

r4#copy tftp flash
Address or name of remote host []? 1.1.1.1
Source filename []? mc3810
Destination filename [mc3810]?

Configuration File Manipulation
The router configuration can reside in several locations: NVRAM, DRAM, terminal, or on a
TFTP server. When the router is booted, the configuration stored in NVRAM is the startup
configuration. After the router is booted, the configuration is placed in DRAM. When users
