MAC-Based IP assignment
One way to use the 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 will be 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.
option config-file "ftp://user:passwd@10.20.4.1//home/user/
S5000-1.conf";
FTP URL with IP address
option config-file "http://myserver/S5000-1.conf";
HTTP URL with hostname
(requires DNS)
option config-file "tftp://10.10.4.1/S5000-1.conf";
TFTP URL with IP address
option config-file "flash://S5000-1.conf";
Flash path relative to /f10/flash
directory
