DESCRIPTION
|
|
"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."

DESCRIPTION
|
|
"This textual convention is an extension of the VlanId
|
|
convention. The VlanId convention defines a greater than zero
|
|
value to identify a VLAN ID in the managed system. The
|
|
CqvVlanIdOrZero convention defines the additional value of
|
|
zero. The value zero is object specific and must therefore be
|
|
defined as part of the description of any object that uses this
|
|
syntax. An example of the usage of zero might include
|
|
situations where the VLAN ID is unknown."

"This 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.
