3. The IP address, boot image filename, and configuration filename are reserved for the system and
provided in the DHCP reply (one-file read method). The system receives its IP address, subnet
mask, DHCP server IP, TFTP server address, DNS server IP, bootfile name, and configuration file-
name from the DHCP server.
4. If a DHCP offer has neither an image path or configuration file path, it is considered an invalid
BMP DHCP offer and is ignored. The first DHCP offers the following to choose:
• IP address
• Dell
Networking OS image
• Configuration file or preconfiguration script
• IP address and Dell Networking OS image or
• IP address and configuration file or preconfiguration script

a filename field is specified in the DHCP offer, the filename can be 128 bytes. The
name can be a fully qualified URL or it can be a filename only.

image to the version currently loaded on the chassis.
