¦ Standard VLAN¦ Smart VLAN¦ Mux VLAN ¦ Super VLAN ¦ QinQ VLAN¦ VLAN Stacking

29Internal Use

Smart VLAN Smart VLAN

qThe Smart VLAN is applied in residential area to provide access to the Internet. With this technology, multiple downstream ports and one or multiple upstream port can be grouped into a Smart VLAN. Meanwhile, the system creates internal mapping between the upstream port and downstream ports to isolate Layer 2 subscribers.

In this networking, the SCU provides GE/FE ports to connect to the MA5600 (or MA5300) frames in subtending. Two types of slave frames are available:

•MA5600 frame. It uses the SCU as the main control board to provide Ethernet uplink ports.

•MA5300 frame. It uses the ESM as the main control board to provide Ethernet uplink ports.
