DHCPOptionList rules editing
1. Valid values: 3,6,12,15,26,28,33, 42,43,66,67,120,121,249;
2. Options in DHCPOptionList parameter are comma-separated without space between them, for example,
DHCPOptionList: "3,6,12,15,26,120,121";
3. Sequence order of options in DHCPOptionList does not matter;
4. Each option (options 12, 15, 42, 43, 66, 67, 120) may be requested and applied only from one interface;
5. Options 1, 3, 6, 26, 28, 33, 121, 249 may be requested by dhcp clients for each subinterface;
6. Options 66 and 67 must be specified on the same interface;
7. If DHCPOptionList is empty, list of options requested by default will be used (take into account section
8);
8. If options specified in DHCPOptionList (see rule 4) are requested from another interface where
DHCPOptionList is empty, these options will be requested from the first interface and will be excluded
from the second interface of the default option list*;
9. If option list is specified for interface in DHCPOptionList, these options will be requested only;
10. Option 1 can not be specified in DHCPOptionList. This option is always requested and applied from all
interfaces regardless of other settings.
If any of the paragraphs is violated, you will see message "Configuration not accepted" after an attempt to
apply configuration. You can find an error if
configd
logs are enabled. In this case, when applying configuration
is unsuccessful you can view the reason why in details.

Example for section 8:
For example, the option list is specified for Internet interface as follows:
Internet.Network.DHCPOptionList: Internet.Network.DHCPOptionList: "3, 6, 26, 28, 33, 121, 249, 12"
For Management interface, nothing is specified: System.ManagementVLAN.DHCPOptionList: ""
If nothing is specified, the default option list including options 3, 6, 12, 15, 26, 28, 33, 42, 43, 66, 67, 121,
249 should be requested according to rule 7 but option 12 will be excluded because of it is specified in
Internet interface.
In the result, option list would be as follows:
Parameter value: Internet.Network.DHCPOptionList: "3, 6, 26, 28, 33, 121, 249, 12" Requested option list:
1, 3, 6, 26, 28, 33, 121, 249, 12. Parameter value: System.ManagementVLAN.DHCPOptionList: ""
Requested option list: 1, 3, 6, 15, 26, 28, 33, 42, 43, 66, 67, 121, 249
We do not recommend this method
Reboot the device after editing DHCPOptionList. Before rebooting, proper device operation is not
guaranteed.
