CISCO-QINQ-VLAN-MIB
AI MIB Summary
The CISCO-QINQ-VLAN-MIB enables the configuration and monitoring of IEEE 802.1QinQ tunneling interfaces on Cisco devices, specifically tracking the mapping and translation of customer edge (CE) VLANs to provider edge (PE) metro tags. It facilitates the management of double-tagged Ethernet frame traffic by exposing metrics related to QinQ interface status, VLAN ID assignments, and tag manipulation logic for service provider network segmentation.
This MIB defines configuration and monitoring capabilities relating to 802.1QinQ interfaces. QinQ interfaces are capable of terminating QinQ traffic and translating QinQ tags.
IEEE 802.1Q VLAN specification provides for an option to tag Ethernet frames with two VLAN tags:
- An inner tag that specifies the customer's VLAN ID. This tag
is called the 'CE VLAN'.
- An outer tag that specifies the service provider's VLAN ID.
This tag is called the 'metro tag', or the 'PE VLAN'.
The combination of inner and outer VLAN tags is used to uniquely identify a particular customer's service flow.

relating to 802.1QinQ interfaces. QinQ interfaces are capable
of terminating QinQ traffic and translating QinQ tags.

Ethernet frames with two VLAN tags:
- An inner tag that specifies the customer's VLAN ID. This tag
is called the 'CE VLAN'.
- An outer tag that specifies the service provider's VLAN ID.
This tag is called the 'metro tag', or the 'PE VLAN'.

identify a particular customer's service flow. MODULE-IDENTITY .1.3.6.1.4.1.9.9.445 |

cqvTerminationTableThis table contains attributes pertaining to QinQ
terminated interfaces.
The ifIndex in the INDEX clause identifies the interface
that terminates QinQ traffic.
A management application can create a conceptual row in this
table by setting the cqvTerminationRowStatus to
'createAndWait' or 'createAndGo'.
A conceptual row in this table cannot be modified while
cqvTerminationRowStatus is set to 'active'. SEQUENCE OF CqvTerminationEntry .1.3.6.1.4.1.9.9.445.1.1.1 |

cqvTranslation OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.445.1.2 |
cqvTranslationTableThis table defines the translations performed on QinQ capable
interfaces.
The ifIndex in the INDEX clause identifies the QinQ interface.
A QinQ interface performs the following translations:
- Double Tagged to Single Tagged - the inner and outer tags of
the frames internal to the switch are replaced with a single
trunk VLAN tag when the outgoing frame is transmitted.
- Double Tagged to Double Tagged - the outer tag of the frames
internal to the switch are replaced with an outer trunk
VLAN tag when the outgoing frame is transmitted. The inner
tag remains unchanged in the transmitted frame.
The following picture illustrates QinQ translations.

Switch

| | Frames | > | Tagged Frames |
| +-| +

Also, the QinQ interface sets the IEEE 802.1P prioritization
bits (P bits) in the outgoing frames by copying the P bits
either from the internal frame's outer or inner VLAN tag.
A management application can create a conceptual row in this
table by setting the cqvTranslationRowStatus to
'createAndWait' or 'createAndGo'.
A conceptual row in this table cannot be modified while
cqvTranslationRowStatus is set to 'active'. SEQUENCE OF CqvTranslationEntry .1.3.6.1.4.1.9.9.445.1.2.1 |
