IBM SC30-3681-08 Accessing Conguration Files From a Remote Host or Router, Example 1 test.cfg

Using the Boot CONFIG Process

2.Con®gure IP so that the device can reach each host with the archived con®guration. TheProtocol Con®guration and Monitoring Referenceexplains the IP con®guration commands.

v The source IP address for TFTP transfers is the device ID. This ID, by default, is

a con®gured IP address for one of the device's network interfaces. To change the router ID, use the set router ID command at the IP Config> prompt.

vAll TFTP data transfers are 512 bytes long. A data transfer of less than 512 bytes indicates an end to the transfer. A protocol, client, or remote host error generates an error packet which terminates the transfer.

vDownload con®guration ®les into the same type of router from which you are uploading the ®le.

Note: This implementation of TFTP does not allow you to copy to other routers.

Every TFTP transfer has a client and server UDP port number. When a client node generates an initial request to the server, an unused UDP port number on the client node is randomly selected as the client port. The server port is the UDP port number 69 (decimal). If a TFTP server is running on the server, it listens on UDP port 69. When the server receives a request from the network, a UDP port number currently unused on the server is randomly selected as the host port. The ®le transfers then occur on these two UDP ports.

Accessing Con®guration Files From a Remote Host or Router

To access con®guration ®les from a remote host or router:

1.At the Boot config> prompt, type copy and press Enter.

2.At the source filename [CONFIG]? prompt, specify the remote IP address and the pathname.

This is the TFTP host or another router with the ®le in its IBD.

3.At the destination filename [Config]? prompt, press Enter.

By pressing Enter you are accepting the default ®lename, CONFIG. For example:

Boot config>copy

source filename[CONFIG]?128.185.210.125:loads/configs/vl-28.cfg destination filename [CONFIG]?

COPYing from "128.185.210.125:loads/configs/vl-28.cfg" to "CONFIG"

COPY succeeded

Filename De®nitions for IBD

Each ®le orimage stored on the IBD must have a unique loadname associated with it. The ®le name for the IBD can contain the complete path name in addition to the ®le name.

Example 1: test.cfg

Example 2: /usr/loads/test.ldc

The following example shows how to store a ®le to the IBD at theBoot config> prompt:

Example: copy 128.185.210.125:/usr/config/test.cfg ibd/test.cfg
