One or more of the following parameters must be configured on the DHCP server.
• Boot File Name: The FTOS image to be loaded on the switch. The boot file name is expected to use
Option 67 or the boot filename in the boot payload of the DHCP offer. If both are specified, Option 67
will be used.
• Configuration File Name: The configurations to be applied to the switch. The configuration file name
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 and external USB memory. If TFTP is used, you can add
Option 66 or Option 150.
• Domain Name Server: (Optional.) The DNS server 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:
• 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
will be unable to download the file from the DHCP server, and will behave as if the server could not be
reached. The discovery process will continue, despite configured time-out, until the stop jump-start com-
mand is given.
