two server models to configure — PowerEdge R730s and PowerEdge R530s, use two SCP files, R730-
config.xml and R530-config.xml.
NOTE: On systems with iDRAC version 2.20.20.20 and later if the file name parameter is not present
in DHCP option 60, the iDRAC server configuration agent automatically generates the configuration
filename using the server Service Tag, model number, or the default filename — config.xml.
The iDRAC server configuration agent uses the rules in the following sequence to determine which SCP
file on the file share to apply for each iDRAC or PowerEdge server:
1. The filename specified in DHCP option 60.
2. <ServiceTag>-config.xml — If a filename is not specified in DHCP option 60, use the system Service
Tag to uniquely identify the SCP file for the system. For example, CDVH7R1-config.xml
3. <Model number>-config.xml — If the option 60 filename is not specified and the <Service Tag>-
config.xml file is not found, then use the system model number as the basis for the SCP file name to
use. For example, R520-config.xml.
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: 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.

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;
