Use the QinQ subtab to provision the IEEE 802.1QinQ VLAN tags on the GE_XP or 10GE_XP cards.
QinQ tags expand the VLAN capability by tagging the tagged packets to produce a “double-tagged” Ethernet frame. For service providers the expanded VLAN allows specific services to be provided on specific VLANs for specific customers, while other types of services can be provided to other customers on other VLANs.

Sets the port where you want to provision QinQ.
|
|
Sets the QinQ mode. The options are:
• |
Selective —Allows you to specify the mapping between CVLANs and SVLANs. See the Selective Mode area described later in this table. |
• |
Transparent —Allows you to specify a single SVLAN. See the Transparent Mode area later in this table. |
|
|
Sets the bridge protocol data unit (BPDU) modes. The options are:
• |
Drop —Discards incoming packets with the MAC address on the BPDU list. |
• |
Tunnel —Transports packets with MAC addresses on the BPDU list. |

Click Add Row to add rows to this area to set the CVLAN and SVLAN mapping. To delete a row, highlight the row and click Remove Row(s). To remove multiple rows, press Ctrl and click the desired rows before clicking Remove Row(s).
|
|
|
|
Choose the SVLAN from the drop-down list.
|
|
Sets the operation mode. The options are:
• |
Add —Appends a new .1Q tag with a specific SVLAN ID to all the incoming Ethernet frames tagged with CVLAN ID. |
• |
Translate —Translates the incoming VLAN ID of the incoming Ethernet frames tagged with CVLAN ID. The CVLAN ID is translated into an SVLAN ID. After this translation, the .1Q tag of the frame is SVLAN. |
• |
Double Add —(GE_XPE and 10GE_XPE cards only) Adds an inner and an outer SVLAN to double tagged packets only. CVLAN settings are not required. |
• |
Translate Add —(GE_XPE and 10GE_XPE cards only) CVLAN gets translated to inner SVLAN and the SVLAN is added. If a double tagged selective operation is present on a port, no other selective operation can be present. |
|
|
Displayed only when the Operation field is set to Double Add or Translate.
• |
If Double Add is chosen in the Operation field, the incoming frame must be untagged and the card will first add the inner SVLAN and then the SVLAN. |
• |
If Translate Add is chosen in the Operation field, the incoming frame must be tagged and the card will translate the CVLAN tag with the Inner SVLAN and then will add the SVLAN. |
|
|
Choose the SVLAN from the drop-down list.

Cancels any changes to the QinQ protection and returns it to its last-saved settings.
