DELL CONFIDENTIAL – PRELIMINARY 8/9/16 - FOR PROOF ONLY
Preparations for Firmware Image Download from TFTP
When an image file is downloaded from TFTP, the following steps are
performed:
The switch downloads the Indirect Image File and extracts from it the
name of the image file.
NOTE:
If the size of the image name bigger than 160 octets only the first 160 octets
will be used.
If the image file version differs from the current image file version, then
the image file is loaded and the switch is rebooted.
Using DHCP and TFTP servers require the following preparations:
TFTP Server
Create a sub directory in the main directory. Place a software image
file in it.
Create an indirect file that contains a path and the name of the
software version (for example indirect-
x10xx
.txt that contains
x10xx
-version.ros).
Copy this file to the TFTP server’s main directory
DHCP Server
Configure the DHCP server with option 20 or 66. This is the IP
address of the TFTP server.
Configure the DHCP server with option 125. Enter the following
information:
A2-02-00-00 — Enterprise Number 674. It should be written from
right to left. 674=A2 02 00 00.
15 — Data Length (in hex)
01 — Sub option code
13 — Sub option length (in hex)
Conversion of the file name (in the above example: conversion of
indirect-
Astute
.txt
from ASCII to HEX is
69 6E 64 69 72 65 63 74 2D 41 73 74 75 74 65 2E 74 78 74.
The following is the complete hex string for the above Option 125
example:
