Integrated Dell Remote Access Controller 7 (iDRAC7) Version 1.50.50 User's Guide
DHCP Options
DHCPv4 allows a large number of 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.
option myname code 43 = text;
option myname "-l 10.35.175.88://xmlfiles –f dhcpProv.xml -u root -p calvin";
where, -l 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. In this example,
root and
calvin are the username
and password to the RFS.
The DHCP Option 60 identifies and associates a DHCP client with a particular vendor. Any DHCP server configured to take action based on a client’s vendor ID should have Option 60 and Option 43 configured. With Dell PowerEdge servers, the iDRAC identifies itself with vendor ID: iDRAC. Therefore, you must add a new ‘Vendor Class’ and create a ‘scope option’ under it for ‘code 60,’ and then enable the new scope option for the DHCP server.
