DUIDRawData=

Specifies the DHCP DUID value as a single newline-terminated, hexadecimal string, with each byte separated by ":". The DUID that is sent is composed of the DUID type specified by DUIDType= and the value configured here.

The DUID value specified here overrides the DUID that systemd-networkd generates using the machine-id from the /etc/machine-id file. To configure DUID per-network, see systemd.network (5). The configured DHCP DUID should conform to the specification in RFC 3315 [2] , RFC 6355 [3] . To configure IAID, see systemd.network(5).

Example 1. A DUIDType=vendor with a custom value

DUIDType=vendor
DUIDRawData=00:00:ab:11:f9:2a:c2:77:29:f9:5c:00

This specifies a 14 byte DUID, with the type DUID-EN ("00:02"), enterprise number 43793 ("00:00:ab:11"), and identifier value "f9:2a:c2:77:29:f9:5c:00".
