-Create Sub-Interfaces
-=====================
-This command is used to add VLAN IDs to interfaces, also known as
-subinterfaces. The primary input to this command is the '*interface*'
-and '*subId*' (subinterface Id) parameters. If no additional VLAN ID is
-provide, the VLAN ID is assumed to be the '*subId*'. The VLAN ID and
-'*subId*' can be different, but this is not recommended.
-
-This command has several variations:
-
-- **create sub-interfaces <interface> <subId>** - Create a subinterface
- to process packets with a given 802.1q VLAN ID (same value as the
- '*subId*').
-- **create sub-interfaces <interface> <subId> default** - Adding the
- '*default*' parameter indicates that packets with VLAN IDs that do
- not match any other subinterfaces should be sent to this
- subinterface.
-- **create sub-interfaces <interface> <subId> untagged** - Adding the
- '*untagged*' parameter indicates that packets no VLAN IDs should be
- sent to this subinterface.
-- **create sub-interfaces <interface> <subId>-<subId>** - Create a
- range of subinterfaces to handle a range of VLAN IDs.
-- **create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any
- [exact-match]** - Use this command to specify the outer VLAN ID, to
- either be explicited or to make the VLAN ID different from the
- '*subId*'.
-- **create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any
- inner-dot1q <vlanId>|any [exact-match]** - Use this command to
- specify the outer VLAN ID and the innner VLAN ID.
-
-When '*dot1q*' or '*dot1ad*' is explictly entered, subinterfaces can be
-configured as either exact-match or non-exact match. Non-exact match is
-the CLI default. If '*exact-match*' is specified, packets must have the
-same number of VLAN tags as the configuration. For non-exact-match,
-packets must at least that number of tags. L3 (routed) interfaces must
-be configured as exact-match. L2 interfaces are typically configured as
-non-exact-match. If '*dot1q*' or '*dot1ad*' is NOT entered, then the
-default behavior is exact-match.
-
-Use the '*show interface*' command to display all subinterfaces.

-Summary/Usage
--------------
-
-.. code-block:: shell
-
- create sub-interfaces <interface> {<subId> [default|untagged]} | {<subId>-<subId>} | {<subId> dot1q|dot1ad <vlanId>|any [inner-dot1q <vlanId>|any] [exact-match]}.

-Examples
---------
-
-Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 11
-
-The previous example is shorthand and is equivalent to:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match
-
-Example of how to create a subinterface number that is different from the VLAN ID:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100
-
-Examples of how to create q-in-q and q-in-any subinterfaces:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
- vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
-
-Examples of how to create dot1ad interfaces:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11
- vpp# create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200
-
-Examples of '*exact-match*' versus non-exact match. A packet with outer VLAN 100 and inner VLAN 200 would match this interface, because the default is non-exact match:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100
-
-However, the same packet would NOT match this interface because '*exact-match*' is specified and only one VLAN is configured, but packet contains two VLANs:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match
-
-Example of how to created a subinterface to process untagged packets:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 5 untagged
-
-Example of how to created a subinterface to process any packet with a VLAN ID that does not match any other subinterface:
-
-.. code-block:: console
-
- vpp# create sub-interfaces GigabitEthernet2/0/0 7 default
-
-When subinterfaces are created, they are in the down state. Example of how to enable a newly created subinterface:
-
-.. code-block:: console
-
- vpp# set interface GigabitEthernet2/0/0.7 up
