.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} 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 }} {{ var5 }} {{ var7 }} dhcp-options client-id 'foo-bar'
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} 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 }} {{ var5 }} {{ var7 }} dhcp-options host-name 'VyOS'
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcp-options vendor-class-id <vendor-id>
This option is used by some DHCP clients to identify the vendor type and
possibly the configuration of a DHCP client. The information is a string of
bytes whose contents are specific to the vendor and are not specified in a
standard.
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 }} {{ var5 }} {{ var7 }} dhcp-options vendor-class-id 'VyOS'
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} 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 }} {{ var5 }} {{ var7 }} dhcp-options no-default-route
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcp-options default-route-distance <distance>
Set the distance for the default gateway sent by the DHCP server.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcp-options default-route-distance 220
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcp-options reject <address>
Reject DHCP leases from a given address or range.
This is useful when a modem gives a local IP when first starting.
* **address** can be specified multiple times,
e.g. 192.168.100.1 and/or 192.168.100.0/24
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcp-options reject 192.168.100.0/24
.. cfgcmd:: set interfaces {{ var0 }} <interface> {{ var2 }} {{ var3 }}
{{ var5 }} {{ var6 }} dhcp-options user-class <string>
This option is used by some DHCP clients as a way for users to specify
identifying information to the client. This can be used in a similar way to
the vendor-class-identifier option, but the value of the option is specified
by the user, not the vendor.
Example:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} {{ var2 }} {{ var4 }} {{ var5 }} {{ var7 }} dhcp-options user-class VyOS
