Service Manual

• IP Address — dynamic IP address for the system. Use this IP address for file transfers only.
The following lists the DHCP option codes.
DHCP Option
Codes
Description
6 Domain Name Server IP
60 Vendor class identifier
61 Class identifier
66 TFTP Server name
67 Boot filename
150 TFTP server IP address
209 Configuration file
230 User port stacking
NOTE: BMP eventually exits when a timeout occurs.
In the following scenarios, BMP requests a different DHCP offer.
• If the offer contains only a boot image that cannot be downloaded, BMP requests another DHCP offer.
• If you enable the reload-type config-scr-download enable command and the configuration file
in the offer cannot be downloaded, BMP requests another DHCP offer.
DHCP Server IP Blacklist
If the process does not complete successfully, the DHCP server IP is blacklisted and the BMP process re-
initiates.
A DHCP server IP is maintained in the blacklist for 10 minutes. If a DHCP offer is received from the blacklisted
DHCP server, the offer is rejected until the IP is alive in the blacklist (10 minutes).
MAC-Based Configuration
To configure the DHCP server to assign a fixed IP address, Dell Networking OS image, and configuration file
based on the system’s MAC address, use BMP mode.
Using BMP, the same IP address is assigned to the system even on repetitive reloads and the same
configuration file is retrieved when using the DNS server or the network-config file to determine the
hostname.
The assigned IP address is only used to retrieve the files from the file server. It is discarded after the files are
retrieved.
