Deploying BSAPs on the Same Layer-2 Subnet as the BSC

If the BSAPs are on the same subnet as the home BlueSecure Controller as shown 

in Figure 3, you can run a DHCP server on the BSC to manage IP address 

assignment to BSAPs. In this scenario, the BlueSecure Controller must be the only 

DHCP server for the subnet.
Alternatively, you can configure the BlueSecure Controller to run a DHCP relay 

agent to relay DHCP communications between the BSAPs and a DHCP server on 

your network.

When you run a DHCP server or a DHCP relay agent on the BSC to assign IP 

addresses to BSAPs on the managed side, the BSC will also pass its IP address to 

the BSAPs automatically using vendor-specific option 43. In this way, the BSAPs 

will learn the home BSC to which they should connect.
See the 

BlueSecure Controller Setup and Administration Guide

 for detailed DHCP 

server and DHCP relay agent configuration procedures.
In this deployment scenario, simply connect and power on the BSAPs. They will 

automatically discover and communicate with their home BSC.

Deploying BSAPs with Layer-3 Connectivity to the BSC

You can also deploy BSAPs on a routed network with Layer-3 connectivity to the 

BSC as shown in Figure 4.
In this deployment scenario, you must ensure that each BSAP is able to 

communicate with the BSC across the routed network by verifying that:
• there are no NAT devices between the BSAPs and the BSC
• Protocol 97 and TCP/UDP Port 33333 traffic is allowed between the BSAPs 

and the BSC

Each BSAP will receive its IP address from your existing network DHCP server.
The BSAP also needs the IP address of the home BSC to which it will connect and 

from which it will obtain its software image and configuration. You can provide 

the home BSC IP address to a BSAP using one of the following methods:
