IBM SC30-3681-08 manual Using the Trivial File Transfer Protocol Tftp

Using the Boot CONFIG Process

constructs a BOOTP reply and adds the client's IP address, along with the location of the Boot server and boot ®lename. If a match does not occur, the packet is dropped.

To add a BOOTP server to the router's con®guration, enter the following command at the IP con®guration prompt:

IP Config> add BOOTP-SERVER [IP address of server]

You can con®gure multiple servers. In addition, if you know only the network number of the server, or if multiple servers reside on the same network segment, you can con®gure a broadcast address for the server using theenable directed-broadcastcommand at the IP config> prompt.

Using the Trivial File Transfer Protocol (TFTP)

TFTP is a ®le transfer protocol that runs over the Internet UDP protocol. This implementation provides multiple, simultaneous TFTP ®le transfers between a router's nonvolatile con®guration memory, Integrated Boot Device (IBD), and remote hosts.

TFTP allows you to:

vStore a con®guration ®le from a router to a server

vCopy a con®guration ®le from a server to a router

vCopy a con®guration or load ®le to an IBD.

TFTP transfers involve a client node and a server node. The client node generates

a TFTP request onto the network. The router acts as a client node by generating TFTP requests from the router console using the Boot Config> process copy

command.

Note: The tftp command and the copy command have the same function but the syntax is different.

The client can transfer a copy of the con®guration ®le stored in con®guration memory, or any ®le stored in the IBD.

The server is any device (for example, a personal computer (PC), router, or workstation) that receives and services the TFTP requests. When the router acts as a server, transfers are transparent to the user. Use the ELS subsystem tftp message log to view the transfer in progress.

Note: A ®le server or router is not allowed tocopy any ®le into another router's nonvolatile con®g memory or IBD. To write to the router, use thecopy command at the destination's local Boot config> prompt.

Before using the copy command, note that:

vThe device con®guration must include the IP protocol and have at least one con®gured IP address. Also, the router must not be operating in CONFIG-Only mode.

vWhen a device's con®guration memory is empty (i.e., initially installing the device, corrupted SRAM), you must set the following parameters to restore the device's con®guration.

1. Set the device's host name.
