- * Create vlan subinterfaces
+ * This command is used to add VLAN IDs to interfaces, also known as subinterfaces.
+ * The primary input to this command is the '<em>interface</em>' and '<em>subId</em>'
+ * (subinterface Id) parameters. If no additional VLAN ID is provide, the VLAN ID is
+ * assumed to be the '<em>subId</em>'. The VLAN ID and '<em>subId</em>' can be different,
+ * but this is not recommended.
+ *
+ * This command has several variations:
+ * - <b>create sub-interfaces <interface> <subId></b> - Create a subinterface to
+ * process packets with a given 802.1q VLAN ID (same value as the '<em>subId</em>').
+ *
+ * - <b>create sub-interfaces <interface> <subId> default</b> - Adding the
+ * '<em>default</em>' parameter indicates that packets with VLAN IDs that do not
+ * match any other subinterfaces should be sent to this subinterface.
+ *
+ * - <b>create sub-interfaces <interface> <subId> untagged</b> - Adding the
+ * '<em>untagged</em>' parameter indicates that packets no VLAN IDs should be sent
+ * to this subinterface.
+ *
+ * - <b>create sub-interfaces <interface> <subId>-<subId></b> - Create a range of
+ * subinterfaces to handle a range of VLAN IDs.
+ *
+ * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any [exact-match]</b> -
+ * Use this command to specify the outer VLAN ID, to either be explicited or to make the
+ * VLAN ID different from the '<em>subId</em>'.
+ *
+ * - <b>create sub-interfaces <interface> <subId> dot1q|dot1ad <vlanId>|any inner-dot1q
+ * <vlanId>|any [exact-match]</b> - Use this command to specify the outer VLAN ID and
+ * the innner VLAN ID.
+ *
+ * When '<em>dot1q</em>' or '<em>dot1ad</em>' is explictly entered, subinterfaces
+ * can be configured as either exact-match or non-exact match. Non-exact match is the CLI
+ * default. If '<em>exact-match</em>' 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 '<em>dot1q</em>' or '<em>dot1ad</em>' is NOT
+ * entered, then the default behavior is exact-match.
+ *
+ * Use the '<em>show interface</em>' command to display all subinterfaces.
*
* @cliexpar
- * @cliexstart{create sub-interfaces}
+ * @parblock
+ * Example of how to create a VLAN subinterface 11 to process packets on 802.1q VLAN ID 11:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11}
*
- * To create a vlan subinterface 11 to process packets on 802.1q VLAN id 11, use:
+ * The previous example is shorthand and is equivalent to:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 11 exact-match}
*
- * vpp# create sub GigabitEthernet2/0/0 11
*
- * This shorthand is equivalent to:
- * vpp# create sub GigabitEthernet2/0/0 11 dot1q 11 exact-match
+ * Example of how to create a subinterface number that is different from the VLAN ID:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100}
*
- * You can specify a subinterface number that is different from the vlan id:
- * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100
*
- * You can create qinq and q-in-any interfaces:
- * vpp# create sub GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200
- * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any
+ * Examples of how to create q-in-q and q-in-any subinterfaces:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1q 100 inner-dot1q 200}
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q any}
*
- * You can also create dot1ad interfaces:
- * vpp# create sub GigabitEthernet2/0/0 11 dot1ad 11
- * vpp# create sub GigabitEthernet2/0/0 12 dot1q 100 inner-dot1q 200
+ * Examples of how to create dot1ad interfaces:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 11 dot1ad 11}
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 12 dot1ad 100 inner-dot1q 200}
*
- * 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.
*
- * For example, a packet with outer vlan 100 and inner 200 would match this interface:
- * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100
+ * Examples of '<em>exact-match</em>' 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:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100}
*
- * but would not match this interface:
- * vpp# create sub GigabitEthernet2/0/0 5 dot1q 100 exact-match
+ * However, the same packet would NOT match this interface because '<em>exact-match</em>'
+ * is specified and only one VLAN is configured, but packet contains two VLANs:
+ * @cliexcmd{create sub-interfaces GigabitEthernet2/0/0 5 dot1q 100 exact-match}
*
- * There are two special subinterfaces that can be configured. Subinterface untagged has no vlan tags:
- * vpp# create sub GigabitEthernet2/0/0 5 untagged
*
- * The subinterface default matches any packet that does not match any other subinterface:
- * vpp# create sub GigabitEthernet2/0/0 7 default
- * @cliexend
+ * Example of how to created a subinterface to process untagged packets:
+ * @cliexcmd{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:
+ * @cliexcmd{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:
+ * @cliexcmd{set interface GigabitEthernet2/0/0.7 up}
