VLANs for Q-in-Q:
In this section must be indicated which of the VLANs will be the ones used in interfaces
QinQ Access, that is, which of the VLANs accepted by the equipment will be sent on
another network through the use of the double tagging. FIGURE 25 shows an example.
•
#.
Indicates the position in the table.
•
VID.
Indicates that the VLAN VID will be sent with double tagging.
•
Name.
A mnemonic descriptive field available to users.
The VID identifiers that are configured for the Q-in-Q function will be used in the
S-Tag, and will therefore be those indicated by the ethernet backbone provider
(usually a third party).
The system does not support that the same VID identifier is in use simultaneously as
a local VLAN and as a reserved VLAN for Q-in-Q. In the case of simultaneity, the use
as a local VLAN is a priority and would not be considered for the operation of Q-in-Q.
