DHCPOptionList Editing Rules
1.
Valid values: 3,6,12,15,26,28,33,40,41,42,43,66,67,120,121,249;
2.
The options in the DHCPOptionList parameter are separated by commas and no spaces between the
options, an example of a DHCPOptionList: '3,6,12,15,26,120,121';
3.
The order of options in DHCPOptionList is not important;
4.
Each of the options 12, 15, 40, 41, 42, 43, 66, 67, 120 can be requested and applied from only 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 nothing is specified in the DHCPOptionList, then the list of requested options will be default (subject
to clause 8);
8.
If the DHCPOptionList specifies the options (from step 4), which by default are requested from another
interface (on which the DHCPOptionList is empty), then the options will be requested from the first
interface, and on the second from the default list these options will be excluded *;
9.
If a list of options is specified for the interface in the DHCPOptionList, then only these options will be
requested;
10.
Option 1 in the DHCPOptionList can not be specified, it is requested and applied always and from all
interfaces regardless of other settings;
If any of the items is breached, then when applying the configuration, the 'Configuration not accepted' message
will be displayed. You can find out the configuration error if you enable the configd logs, then when applying the
configuration, the reason for which the configuration is not applied will be indicated in detail.
* Example for item 8:
Suppose the following list of options is specified for the Internet interface: Internet.Network.DHCPOptionList: '3,
6, 26, 28, 33, 121, 249, 12'
And for the managment interface nothing is specified: System.ManagementVLAN.DHCPOptionList: ""
then, according to unit 7, the default option list should be 3, 6, 12, 15, 26, 28, 33, 40, 41, 42, 43, 66, 67, 121, 249,
but since option 12 is explicitly specified on the Internet interface, it will be excluded from this list.
Finally the following lists will appear:
parameter value: Internet.Network.DHCPOptionList: '3, 6, 26, 28, 33, 121, 249, 12' requested list of options: 1, 3,
6, 26, 28, 33, 121, 249, 12 parameter value: System.ManagementVLAN.DHCPOptionList: ""
requested list of options: 1, 3, 6, 15, 26, 28, 33, 40, 41, 42, 43, 66, 67, 121, 249
After editing the DHCPOptionList, device reboot is recommended. Correct device operation is not
guaranteed until the device is rebooted.
