.. 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
