| 33 | * @file |
| 34 | * @brief Ethernet VLAN Tag Rewrite. |
| 35 | * |
| 36 | * VLAN tag rewrite provides the ability to change the VLAN tags on a packet. |
| 37 | * Existing tags can be popped, new tags can be pushed, and existing tags can |
| 38 | * be swapped with new tags. The rewrite feature is attached to a subinterface |
| 39 | * as input and output operations. The input operation is explicitly configured. |
| 40 | * The output operation is the symmetric opposite and is automatically derived |
| 41 | * from the input operation. |

| 625 | * VLAN tag rewrite provides the ability to change the VLAN tags on a packet. |
| 626 | * Existing tags can be popped, new tags can be pushed, and existing tags can |
| 627 | * be swapped with new tags. The rewrite feature is attached to a subinterface |
| 628 | * as input and output operations. The input operation is explicitly configured. |
| 629 | * The output operation is the symmetric opposite and is automatically derived |
| 630 | * from the input operation. |
| 631 | * |
| 632 | * <b>POP:</b> For pop operations, the subinterface encapsulation (the vlan |
| 633 | * tags specified when it was created) must have at least the number of popped |
| 634 | * tags. e.g. the \"pop 2\" operation would be rejected on a single-vlan interface. |
| 635 | * The output tag-rewrite operation for pops is to push the specified number of |
| 636 | * vlan tags onto the packet. The pushed tag values are the ones in the |
| 637 | * subinterface encapsulation. |
| 638 | * |
| 639 | * <b>PUSH:</b> For push operations, the ethertype is also specified. The |
| 640 | * output tag-rewrite operation for pushes is to pop the same number of tags |
| 641 | * off the packet. If the packet doesn't have enough tags it is dropped. |
| 642 | * |
| 643 | * |
| 644 | * @cliexpar |
| 645 | * @parblock |
| 646 | * By default a subinterface has no tag-rewrite. To return a subinterface to |
| 647 | * this state use: |
| 648 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 disable} |
| 649 | * |
| 650 | * To pop vlan tags off packets received from a subinterface, use: |
| 651 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 1} |
| 652 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 pop 2} |
| 653 | * |
| 654 | * To push one or two vlan tags onto packets received from an interface, use: |
| 655 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1q 100} |
| 656 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 push dot1ad 100 150} |
| 657 | * |
| 658 | * Tags can also be translated, which is basically a combination of a pop and push. |
| 659 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-1 dot1ad 100} |
| 660 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-2 dot1ad 100 150} |
| 661 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 1-2 dot1q 100} |
| 662 | * @cliexcmd{set interface l2 tag-rewrite GigabitEthernet0/8/0.200 translate 2-1 dot1q 100 150} |
| 663 | * |
| 664 | * To display the VLAN Tag settings, show the associate bridge-domain: |
| 665 | * @cliexstart{show bridge-domain 200 detail} |
