Bare Metal Provisioning 2.0 | 257
Following is an example of a configuration of the DHCP server included on the most popular Linux
distributions. The dhcpd.conf file shows assignment of a fixed IP address and configuration file based on
the MAC address of the switch.
DHCP Retry Mechanism
BMP will request a different DHCP offer in the following scenarios:
• If the command
reload-type config-download is enabled, the DHCP offer specifies both the boot image
and the configuration file, and either download is successful, BMP will not request another DHCP
offer.
• If the offer contains only a boot image that cannot be downloaded, BMP will request another DHCP
offer.
• If the command
reload-type config-download is enabled and the configuration file in the offer cannot be
downloaded, BMP will request another DHCP offer.
DHCP Server IP Blacklist
If the process does not complete successfully, the DHCP server IP will be blacklisted and the DHCP
process will be re-initiated. A DHCP server is maintained in the blacklist for ten minutes. If a DHCP offer
is received from the blacklisted DHCP server, the offer will be rejected.
