Jumpstart Mode
Jumpstart (BMP) mode is the default boot mode congured for a new switch arriving from Dell Networking. This mode obtains the Dell
Networking OS image and conguration le from a network source (DHCP server and le server).
DHCP Server/Conguration
You must rst congure an external DHCP server before you can use Jumpstart mode on a switch. Congure the DHCP server with the
following parameters for each client switch. The DHCP server is congured to assign an IP address to the switch and specify the les to
download.
For more information, refer to the Dell Networking OS Conguration Guide, the Dynamic Host Conguration Protocol chapter.
Congure 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 lename is expected to use Option 67 or the boot
lename in the boot payload of the DHCP oer. If both are specied, Option 67 is used.
• Conguration File Name: The congurations to apply to the switch. The conguration lename is expected to use Option 209.
• File Server Address: The server where the Image and Congurations le 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 les 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 le transfers.
The DHCP option codes used are:
DHCP Option
Code
Description
6 Domain Name Server IP
66 TFTP Server name
67 Boot lename
150 TFTP server IP address
209 Conguration File
NOTE: The boot le name and conguration le name must be in the correct format. If it is not, the switch is unable to download
the le from the DHCP server and behaves as if the server could not be reached. The discovery process continues, despite
congured time-out, until you enter the stop jump-start command.
