Once the SV1 is connected, packets coming into a switch port is re-directed to the SVI and onto the BD.
On entering the BD, the source MAC address is learned and the packet is bridged. In the opposite
direction, packets coming onto the BD from an EVC via the switch port are directed out the SVI.

Configuring SVI as Access Port

First you configure the switch port to add an access port SVI to a BD. After this you need to define the
associated VLAN interface.
The BD id does not have to match the VLAN id in the dot1q tag, but all packets on the BD must be tagged
Note
with that VLAN number. So an EVC could be configured in which the BD id matches the VLAN id.

Configuration Examples to add an Access Port SVI to a BD

This example shows how to add an Access Port SVI to a BD:

Only one SVI may be associated with a BD.
There is no EVC (i.e. service instance) configuration on an SVI.
All packets on the BD, including those from EVCs, should be tagged, with the VLAN tag specifying
the VLAN id of the SVI.
Only access port configurations are supported.
