Broadcasts: If the unit is set up for DHCP, it will send out the necessary broadcasts
in order to obtain a valid IP address. Also, the unit will occasionally send out an
ARP request. All other communications are unicast.
The amount of traffic generated by, or routed to the Crestron system all depends
on the customized program that has been uploaded, and the amount of
connections that are made.
One of the features of the Crestron Control Processor is that it has a built-in Web
server. This Web server is used for serving up pages that communicate directly
with the processor. These pages contain HTML, as well as Java or ActiveX objects.
Static or DHCP?
Because of the many uses of the Crestron Control System (Server, IP to RS232
Gateway, NAT Router), and the fact that many diverse clients connect to the
processor over IP, it may be desired to configure the systems for static IP
addresses (as would a web server, or a router).
Crestron Control Systems also provide DHCP support with the following
configurations:
DHCP + Dynamic DNS (Windows 2000)
The DHCP Scope has to include the following options:
- 003 – Router
- 006 – DNS Servers
- 015 – Domain Name
The DHCP Scope should have the following settings enabled:
- Always dynamically update all nodes
- Enable updating of nodes that don’t support dynamic DNS
The DNS Server should have the following setting enabled:
- Handle Dynamic Updates
DHCP + WINS + DNS (Windows 2000 or Windows NT 4)
The DHCP Scope has to include the following options:
- 003 – Router
- 006 – DNS Servers
- 015 – Domain Name
- 044 – WINS/NBNS Servers
- 040 – WINS/NBT Node Type (Set value to ‘0x2’)
The DNS Server should have the following setting enabled:
- Enable WINS Resolution (Windows NT 4.0)
- Enable WINS Forward Lookup (Windows 2000)
