- * VLAN tag rewrite provides the ability to change the VLAN tags on a packet.
- * Existing tags can be popped, new tags can be pushed, and existing tags can
- * be swapped with new tags. The rewrite feature is attached to a subinterface
- * as input and output operations. The input operation is explicitly configured.
- * The output operation is the symmetric opposite and is automatically derived
- * from the input operation.
- *
- * <b>POP:</b> For pop operations, the subinterface encapsulation (the vlan
- * tags specified when it was created) must have at least the number of popped
- * tags. e.g. the \"pop 2\" operation would be rejected on a single-vlan interface.
- * The output tag-rewrite operation for pops is to push the specified number of
- * vlan tags onto the packet. The pushed tag values are the ones in the
- * subinterface encapsulation.
- *
- * <b>PUSH:</b> For push operations, the ethertype is also specified. The
- * output tag-rewrite operation for pushes is to pop the same number of tags
- * off the packet. If the packet doesn't have enough tags it is dropped.
- *
- *
- * @cliexpar
- * @parblock
- * By default a subinterface has no tag-rewrite. To return a subinterface to
- * this state use:

- * To pop vlan tags off packets received from a subinterface, use:
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 1}
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 2}
- *
- * To push one or two vlan tags onto packets received from an interface, use:
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1q 100}
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1ad 100 150}
- *
- * Tags can also be translated, which is basically a combination of a pop and push.
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-1 dot1ad 100}
- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-2 dot1ad 100 150}

- * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-1 dot1q 100 150}
