Listen Ports

On the Control Subnet, the number of listen ports on the LAN changes. There are an additional 100 listen ports.

Crestron utilizes listen ports 64,000 to 64,099 as the range which can be changed. Listen ports are used for

Crestron conﬁguration changes for Crestron devices on the Control Subnet and dynamically open and close.

Control Subnet Example

IP Addressing

Automatic Mode (Default)

In order to eliminate routing conﬂicts between the Control Subnet and the LAN, the Control Subnet IP address is

automatically set based on the LAN-side Ethernet conﬁguration. Refer to the table below for more information on

Control Subnet IP addressing in automatic mode.

LAN Control Subnet

Class A Class B (172.22.0.0/16)

Class B Class A (10.0.0.0/8)

Class C Class B (172.22.0.0/16)

Manual Mode

There is usually no need to change the Automatic Settings and there is no conﬂict. If necessary, the user can set

the routing preﬁx for the Control Subnet manually. This should only be done if the LAN contains a network that

conﬂicts with the Control Subnet.

NOTE: If the routing preﬁx is set on the Control Subnet any reserved leases are erased and the control system no

longer checks for routing conﬂicts between the LAN and the control system. It is important that the user is familiar

with this procedure before proceeding.
