  2. Under DHCP Services in the left sidebar, select the applicable Kea DHCP server.
  3. On the Action or Row ... menu, select either Manage DHCPv4 options or Manage DHCPv6 options.

    To delete an option, hover over it, and then select the trash can icon that appears to the right of the input field.

  5. Select Save.

Viewing custom DHCP options

At any time, you can check which custom DHCP options are defined on an ISC Kea DHCP server, so you can manage them accordingly.

To view the defined custom DHCP options:

  1. Locate the Kea DHCP server in the Service management data grid.
  2. Use either the Action or Row ... menu to select either Manage custom DHCPv4 options or Manage custom DHCPv6 options.
  3. Use the Vendor class dropdown to filter the list of custom options.

The dialog displays a list of all the custom DHCP options defined on the server. From here, you can edit custom options and remove them, if necessary.

Adding custom DHCP options

You can add custom DHCP options to your ISC Kea DHCP server to tailor it to your needs. Once you define a custom option, you can set its value in the Manage DHCPv4 options or Manage DHCPv6 options tasks, respectively. Refer to the section above for instructions on managing standard DHCP options.

  1. Locate the Kea DHCP server in the Service management data grid.
  2. Use either the Action or Row ... menu to select either Manage custom DHCPv4 options or Manage custom DHCPv6 options.

  4. Enter the desired ID number for the option. An error will be displayed if that ID is not available or invalid.
    Note: All options from 1–120 are predefined.
  5. Enter a name for the option.
  6. Select a type in the dropdown, e.g., string, hexadecimal, boolean, IP address, number (8-bit, 16-bit, or 32-bit).
  7. If the Type is IP address, select the Array checkbox if the option is an array.
  8. Select Add, and then Save.

You can now manage the custom option's value from the Manage DHCP options dialog.
