   dhcp-options client-id <description>

  :rfc:`2131` states: The client MAY choose to explicitly provide the identifier
  through the 'client identifier' option. If the client supplies a 'client
  identifier', the client MUST use the same 'client identifier' in all
  subsequent messages, and the server MUST use that identifier to identify the
  client.

  Example:

  .. code-block:: none

    set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} dhcp-options client-id 'foo-bar'

.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
  dhcp-options host-name <hostname>

  Instead of sending the real system hostname to the DHCP server, overwrite the
  host-name with this given-value.

  Example:

  .. code-block:: none

    set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} dhcp-options host-name 'VyOS'

.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
  dhcp-options vendor-class-id <vendor-id>

  The vendor-class-id option can be used to request a specific class of vendor
  options from the server.

  Example:

  .. code-block:: none

    set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} dhcp-options vendor-class-id 'VyOS'

.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
  dhcp-options no-default-route

  Only request an address from the DHCP server but do not request a default
  gateway.

  Example:

  .. code-block:: none

    set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} dhcp-options no-default-route
