25.9.6 DHCP BMC Hostname
The BMC allows setting a DHCP Hostname using the Set/Get LAN Configuration Parameters command.
x DHCP Hostname can be set regardless of the IP Address source configured on the BMC. But this parameter will
only be used if the IP Address source is set to DHCP.
x When Byte 2 is set to “Update in progress”, all the 16 Block Data Bytes (Bytes 3 – 18) must be present in the
request.
