Understanding Hierarchical Deployment

An AP with more than one wired port) can be connected to the downlink wired port of
another AP (Ethernet X). An AP with a single Ethernet port (like AP-90 or AP-100 Series
access points) can be provisioned to use Ethernet bridging, so that Ethernet 0 port is
converted to a downlink wired port.
You can also form an AP network by connecting the downlink port of an AP to other APs.
Only one AP in the network uses its downlink port to connect to the other APs. This AP
(called the root AP) acts as the wired device for the network, provides DHCP service and an
L3 connection to the ISP uplink with NAT. The root AP is always the master of the
SCALANCE W network. In a single Ethernet port platform deployment, the root AP must be
configured to use the 3G uplink.
A typical hierarchical deployment consists of the following:
● A direct wired ISP connection or a wireless uplink.
● One or more DHCP pools for private VLANs.
● One downlink port configured on a private VLAN without authentication for connecting to
slave APs. Ensure that the downlink port configured in a private VLAN is not used for any
wired client connection. Other downlink ports can be used for connecting to the wired
clients.
The following figure illustrates a hierarchical deployment scenario:
