Jumpstart Mode
Jumpstart (BMP) mode is the default boot mode configured for a new switch arriving from Dell
Networking. This mode obtains the Dell Networking OS image and configuration file from a network
source (DHCP server and file server).
DHCP Server/Configuration
You must first configure an external DHCP server before you can use Jumpstart mode on a switch.
Configure the DHCP server with the following parameters for each client switch. The DHCP server is
configured to assign an IP address to the switch and specify the files to download.
For more information, refer to the Dell Networking OS Configuration Guide, the Dynamic Host
Configuration Protocol chapter.
Configure one or more of the following parameters on the DHCP server:
• Boot File Name: The Dell Networking OS image to load on the switch. The boot filename is expected
to use Option 67 or the boot filename in the boot payload of the DHCP offer. If both are specified,
Option 67 is used.
• Configuration File Name: The configurations to apply to the switch. The configuration filename is
expected to use Option 209.
• File Server Address: The server where the Image and Configurations file are placed. The address is
assumed to be a TFTP address unless it is given as a URL. The switch supports TFTP, HTTP, and FTP
protocols, as well as files stored in Flash. If TFTP is used, you can add Option 66 or Option 150.
• Domain Name Server: (Optional.) The domain name server (DNS) to be contacted to resolve the
hostname through Option 6.
• IP Address: Dynamic IP address for the switch. This is used only for file transfers.
The DHCP option codes used are:
DHCP Option
Code
Description
6 Domain Name Server IP
66 TFTP Server name
67 Boot filename
150 TFTP server IP address
209 Configuration File
NOTE: The boot file name and configuration file name must be in the correct format. If it is not, the
switch is unable to download the file from the DHCP server and behaves as if the server could not
be reached. The discovery process continues, despite configured time-out, until you enter the stop
jump-start
command.
