Extra DHCP Options

DHCP options can be configured using extra-dhcp-options option in the following Neutron command. This support is available from R1.10 onwards.
neutron port-create net1 --extra-dhcp-opts list=true opt_name='dhcp_option_name',opt_value='value'
Example : neutron port-create net1 --extra-dhcp-opts list=true opt_name='interface-mtu',opt_value='9000' to set the MTU option to 9000
The following table lists the DHCP options, their options names and expected values to be used in the --extra-dhcp-opts option. The opt_name field can have either the DHCP code or the DHCP name specified below for the corresponding code.
From R2.21, an additional field (dhcp-option-value-bytes) is added to DhcpOptionType to take the option value in bytes (in decimal). This value can be set using VNC API and can be used with options having option value as a String (see below). The bytes that need to be sent for the DHCP option can be set in this field, space separated and in decimal. For example, to send value 1 followed by TEST in option 43, set dhcp-option-value-bytes for option 43 to "01 84 69 83 84" (84, 69, 83 and 84 being ascii for TEST). For options where dhcp-option-value-bytes is used, it takes higher precedence than dhcp-option-value.
