5. User s M anual of VDSL 2 Switch The Managed Switch supports multiple VLAN tags and can therefore be used in MAN applications as a provider bridge aggregating traffic from numerous independent customer LANs into the MAN Metro Access Network space One of the purposes of the provider bridge is to recognize and use VLAN tags so that the VLANs in the MAN space can be used independent of the customers VLANs This is accomplished by adding a VLAN tag with a MAN related VID for frames entering the MAN When leaving the MAN the tag is stripped and the original VLAN tag with the customer related VID is again available This provides a tunneling mechanism to connect remote costumer VLANs through a common MAN space without interfering with the VLAN tags All tags use Ether Type 0x8100 or 0x88A8 where 0x8100 is used for customer tags and 0x88A8 are used for service provider tags In cases where a given service VLAN only has two member ports on the switch the learning can be disabled for the particular VLAN and can therefore rely on flooding as the forwarding mechanism between the two ports This way the MAC table requirements is reduced 4 4 5 1 Q in Q Port Setting The QinQ VLAN QinQ Port Setting screen in Figure 4 4 8 appears QinQ VLAN Enable y Figure 4 4 8 Q in Q Port Setting interface The page includes the following fields 79 User s M anual of VDSL 2 Switch Object Description
