• Boot File Name: The Dell Networking OS 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. 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:

• Domain Name Server IP: 6

• TFTP Server name: 66

• Boot filename: 67

• TFTP server IP address: 150

• Configuration File: 209

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 and the configured time-out is ignored until you enter the

stop jump-start command.

If a configuration cannot be downloaded, the following system messages are logged:

00:02:02:%STKUNIT0-M:CP %JUMPSTART-2-JUMPSTART_DOWNLOAD_ERROR: The config file down-

load failed due to unreachable server ip or invalid URL.

00:02:02:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_RELEASE: DHCP RELEASE sent on Te 0/10

After 10 minutes of rediscovery attempts, the server IP address is blacklisted as shown in the system log:

00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/

47.

00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Ma 0/0.

00:05:45:%STKUNIT0-M:CP %JUMPSTART-5-DHCP_OFFER_REJECTED: Server IP address

10.11.197.39 was previously rejected.

00:05:59:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/0.

00:05:59:%STKUNIT0-M:CP %JUMPSTART-5-JUMPSTART_DISCOVER: DHCP DISCOVER sent on Te 0/1.
