MAC-Based IP Assignment
One way to use BMP mode most efficiently is to configure the DHCP server to assign a fixed IP address, Dell
Networking OS image, and configuration file based on the switch’s MAC address.
When this is done, the same IP address is assigned to the switch 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.
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.
