option (DHCP server)


Hierarchy Level


Configure one or more user-defined options that are not included in the Junos default implementation of the DHCP server. For example, if a client requests a DHCP option that is not included in the DHCP server, you can create a user-defined option that enables the server to respond to the client’s request.


  • id-number—Any whole number. The ID number is used to index the option and must be unique across a DHCP server.

  • option-type—Any of the following types: byte, byte-stream, flag, integer, ip-address, short, string, unsigned-integer, unsigned-short.

  • array—An option can include an array of values.

  • option-value—Value associated with an option. The option value must be compatible with the option type (for example, an On or Off value for a flag type).
