– If either the image or the configuration download is successful, BMP does not request another
DHCP offer.
– If the image download is successful but the configuration download fails, the switch boots up with
the default configuration.
– If the image download fails, the switch does not try to download the configuration file and starts
sending requests for a new DHCP offer from a different server. The previously offered server is
blacklisted.
• If the offer contains only a boot image that cannot be downloaded, BMP requests another DHCP
offer.
• If you enable the reload-type config-download command and the configuration file in the offer
cannot be downloaded, the switch boots up and loads the startup configuration stored in local flash
memory.
DHCP Server IP Blacklist
If the process does not complete successfully, the DHCP server IP is blacklisted and the DHCP process is
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 is rejected.
File Server
Set up a file server and ensure connectivity.
You must configure the server that holds the boot and configuration files as the network source for the
switch. The switch recognizes HTTP, TFTP, FTP, and Flash URLs.
For example:
• tftp://serverip/filename
• tftp://hostname/filename
• ftp://user:passwd@serverip//mypath/filename
• ftp://user:passwd@hostname//mypath/filename
• http://serverip/filename
• http://hostname/filename
• flash://filename
• filename (Assumes TFTP)
When loading the Dell Networking OS image, if the Dell Networking OS image on the server is different
from the image on the local flash, the switch downloads the image from the server onto the local flash
and reloads using that image.
Next, the switch tries to load the configuration file. If the configuration file is not specified or if you
disable the config-download parameter, the switch loads the startup-config from the local flash.
Domain Name Server
Set up a DNS to determine the host name applied in the switch startup configuration when no
configuration file is retrieved from the DHCP server.
The DNS server is contacted only when no configuration file is contained in a DHCP server response and
the host name is not resolved from the network-config file on the switch. For more information, refer to
the Dell Networking OS Configuration Guide, the IPv4 Addressing chapter.
