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
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:
• DHCP Server Option 43 - You can manually configure the DHCP server
on your network to send BSC IP addresses to BSAPs using DHCP vendor-
specific option 43.
In DHCP requests sent from the BSAP, the BSAP uses option 60 Vendor class
identifier with a value of BlueSecure.AP1500 to identify itself to the DHCP
server.
Refer to the documentation supplied with your DHCP server when configuring
vendor-specific option 43
