FIGURE 17-1 Example Two Topology
This section covers some basic network configuration required to allow the
Access Points to use the Alcatel Discovery Protocol to discover the Alcatel
Mobility Controller.
1. In this example, configure an IP helper address on the Layer-3 switch on
the same subnet as the Access Points with the IP address of the Alcatel
Mobility Controller. Additionally, configure an IP helper address on the Layer-3
switch for the DHCP server that serves the subnet of the APs.
