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.
