+Set Interface Commands
+======================
+
+This section covers those commands that are related to setting an
+interface:
+
+-  `Set Interface IP Address <#set-interface-ip-address>`__
+-  `Set Interface L2 Bridge <#set-interface-l2-bridge>`__
+-  `Set Interface MTU <#set-interface-mtu>`__
+-  `Set Interface Promiscuous <#set-interface-promiscuous>`__
+-  `Set Interface State <#set-interface-state>`__
+
+.. note::
+
+   For a complete list of CLI Debug commands refer to the Debug CLI
+   section of the `Source Code
+   Documents <https://docs.fd.io/vpp/18.07/clicmd.html>`__ .
+
+Set Interface IP Address
+========================
+
+.. code:: console
+
+   set interface ip address [del] <*interface*> <*ip-addr*>/<*mask*> | [all]
+
+Add an IP Address to an interface or remove and IP Address from an
+interface. The IP Address can be an IPv4 or an IPv6 address. Interfaces
+may have multiple IPv4 and IPv6 addresses. There is no concept of
+primary vs. secondary interface addresses; they're just addresses.
+
+To display the addresses associated with a given interface, use the
+command **show interface address** <*interface*>.
+
+.. note::
+
+   The debug CLI does not enforce classful mask-width / addressing
+   constraints.
+
+Example Usage
+-------------
+
+An example of how to add an IPv4 address to an interface:
+
+.. code:: console
+
+   vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24
+
+An example of how to add an IPv6 address to an interface:
+
+.. code:: console
+
+   vpp# set interface ip address GigabitEthernet2/0/0 ::a:1:1:0:7/126
+
+To delete a specific interface ip address:
+
+.. code:: console
+
+   vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24 del
+
+To delete all interfaces addresses (IPv4 and IPv6):
+
+.. code:: console
+
+   vpp# set interface ip address GigabitEthernet2/0/0 del all
+
+Declaration and Implementation
+------------------------------
+
+**Declaration:** set_interface_ip_address_command
+(src/vnet/ip/ip46_cli.c line 216)
+
+**Implementation:** add_del_ip_address
+
+Set Interface L2 Bridge
+=======================
+
+.. code:: console
+
+    set interface l2 bridge <*interface*> <*bridge-domain-id*> [bvi|uu-fwd]
+    [shg]
+
+Use this command put an interface into Layer 2 bridge domain. If a
+bridge-domain with the provided bridge-domain-id does not exist, it will
+be created. Interfaces in a bridge-domain forward packets to other
+interfaces in the same bridge-domain based on destination mac address.
+To remove an interface from a the Layer 2 bridge domain, put the
+interface in a different mode, for example Layer 3 mode.
+
+Optionally, an interface can be added to a Layer 2 bridge-domain as a
+Bridged Virtual Interface (bvi). Only one interface in a Layer 2
+bridge-domain can be a bvi.
+
+Optionally, a split-horizon group can also be specified. This defaults
+to 0 if not specified.
+
+.. _example-usage-1:
+
+Example Usage
+-------------
+
+Example of how to configure a Layer 2 bridge-domain with three
+interfaces (where 200 is the bridge-domain-id):
+
+.. code:: console
+
+   vpp# set interface l2 bridge GigabitEthernet0/8/0.200 200
+
+This interface is added a BVI interface:
+
+.. code:: console
+
+   vpp# set interface l2 bridge GigabitEthernet0/9/0.200 200 bvi
+
+This interface also has a split-horizon group of 1 specified:
+
+.. code:: console
+
+   vpp# set interface l2 bridge GigabitEthernet0/a/0.200 200 1
+
+Example of how to remove an interface from a Layer2 bridge-domain:
+
+.. code:: console
+
+   vpp# set interface l3 GigabitEthernet0/a/0.200

+Declaration and Implementation

+
+**Declaration:** int_l2_bridge_cli (src/vnet/l2/l2_input.c line 949)
+
+**Implementation:** int_l2_bridge
+
+Set Interface MTU
+=================
+
+.. code:: shell
+
+   set interface mtu [packet|ip4|ip6|mpls] <value> <interface>
+
+Set Interface Promiscuous
+=========================
+
+.. code:: shell
+
+   set interface promiscuous [on|off] <interface>.
+
+.. _setintstate:
+
+Set Interface State
+===================
+
+This command is used to change the admin state (up/down) of an
+interface.
+
+If an interface is down, the optional *punt* flag can also be set. The
+*punt* flag implies the interface is disabled for forwarding but punt
+all traffic to slow-path. Use the *enable* flag to clear *punt* flag
+(interface is still down).
+
+.. code:: shell
+
+   set interface state <interface> [up|down|punt|enable].
+
+.. _example-usage-2:
+
+Example Usage
+-------------
+
+Example of how to configure the admin state of an interface to **up**:
+
+.. code:: console
+
+   vpp# set interface state GigabitEthernet2/0/0 up
+
+Example of how to configure the admin state of an interface to **down**:
+
+.. code:: console
+
+   vpp# set interface state GigabitEthernet2/0/0 down
