According to the table, options 1, 3, 6, 26, 28, 33, 121, 249 can be requested by DHCP clients for each
subinterface. Accordingly, these options will be individually applied for each subinterface. Options 12, 15, 40, 41,
42, 43, 66, 67, 120 can be requested and used only for one DHCP client, since they are system-wide, that is, they
do not lead to the network interface configuration.
The requested options list configuration can be changed and it is stored like all other settings in the
configuration file:
/etс/config/cfg.yaml.
By default, the option lists are not specified (the configuration contains
the following DHCPOptionList entry: ""), this means that the options are requested and applied according to the
table above.
