For iDRAC firmware 3.00.00.00 or later, JSON format Profile files are supported. The following file names will be used if the
Filename parameter is not present:
● <service tag>-config.xml, Example: CDVH7R1-config.xml
● <model number>-config.xml, Example: R640-config.xml
● config.xml
● <service tag>-config.json, Example:CDVH7R1-config.json
● <model number>-config.json, Example: R630-config.json
● config.json
NOTE: More information about HTTP can be found in the 14G Support for HTTP and HTTPS across IDRAC9 with Lifecycle
Controller Interfaces white paper at www.dell.com/support.
NOTE:
● Auto Config can only be enabled when DHCPv4 and the Enable IPV4 options are enabled.
● Auto Config and Auto Discovery features are mutually exclusive. Disable Auto Discovery for Auto Config to work.
● The Auto Config is disabled after a server has carried out an Auto Config operation.
If all the Dell PowerEdge servers in the DHCP server pool are of the same model type and number, then a single SCP file
(config.xml) is required. The config.xml file name is used as the default SCP file name. In addition to .xml file, .json
files can also be used with 14G systems. The file can be config.json.
The user can configure individual servers requiring different configuration files mapped using individual server Service Tags or
server models. In an environment that has different servers with specific requirements, different SCP file names can be used
to distinguish each server or server type. For example, if there are two server models to configure — PowerEdge R740s and
PowerEdge R540s, use two SCP files, R740-config.xml and R540-config.xml.
NOTE:
iDRAC server configuration agent automatically generates the configuration filename using the server Service Tag,
model number, or the default filename — config.xml.
NOTE: If none of these files are on the network share, then the server configuration profile import job is marked as failed
for file not found.
Auto Config sequence
1. Create or modify the SCP file that configures the attributes of Dell servers.
2. Place the SCP file in a share location that is accessible by the DHCP server and all the Dell servers that are assigned IP
address from the DHCP server.
3. Specify the SCP file location in vendor-option 43 field of DHCP server.
4. The iDRAC while acquiring IP address advertises vendor class identifier. (Option 60)
5. The DHCP server matches the vendor class to the vendor option in the dhcpd.conf file and sends the SCP file location
and, if specified the SCP file name to the iDRAC.
6. The iDRAC processes the SCP file and configures all the attributes listed in the file.
DHCP options
DHCPv4 allows many globally defined parameters to be passed to the DHCP clients. Each parameter is known as a DHCP
option. Each option is identified with an option tag, which is a 1-byte value. Option tags 0 and 255 are reserved for padding and
end of options, respectively. All other values are available for defining options.
The DHCP Option 43 is used to send information from the DHCP server to the DHCP client. The option is defined as a text
string. This text string is set to contain the values of the SCP filename, share location and the credentials to access the location.
For example,
option myname code 43 = text;
subnet 192.168.0.0 netmask 255.255.255.0 {
# default gateway
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
option nis-domain "domain.org";
option domain-name "domain.org";
option domain-name-servers 192.168.1.1;
option time-offset -18000; #Eastern Standard Time
