4. config.xml — If the option 60 filename, service tag-based, and model number-based files are not available, use the default
config.xml file.
NOTE: To set the workload profile along with other attributes using SCP, ensure that you run the SCP import job twice
to get the correct configuration changes.
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.
For iDRAC firmware 2.70.70.70 and later versions, 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: R630-config.xml)
• "config.xml"
• "<service tag>-config.json" (Example: CDVH7R1-config.json)
• "<model number)-config.json" (Example: R630-config.json)
• "config.json"

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 as part of acquiring IP address advertises vendor class identifier iDRAC. (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 XML 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
option vendor-class-identifier "iDRAC";
set vendor-string = option vendor-class-identifier;
option myname "-f system_config.xml -i 192.168.0.130 -u user -p password -n cifs -s 2 -d
0 -t 500";
where, -i is the location of the Remote File Share and –f is the file name in the string along with the credentials to the Remote File Share.
