Shrinking the subnet

If you want to use multiple CineStations or have to access a WiFi network in the same subnet as your VRI device you might need to shrink the subnet mask from 255.255.0.0 to 255.255.255.0 or even smaller. For this how-to let’s assume your CineStation has the following configuration:

IP: 100.100.33.111
netmask: 255.255.0.0

XIP: 172.16.0.222
netmask: 255.255.0.0

To change the network settings of your CineStation let’s connect to the 1GbE interface and configure it accordingly. Use the IP 100.100.0.123 for your machines network 1GbE interface with a netmask of 255.255.0.0. If your 10GbE interface has two ports, I suggest you use one for 1GbE and one for 10GbE connection. Don’t connect them both at the same time to the same CineStation though.

The following command will change the netmask of the CineStations 10GbE interface to 255.255.255.0:

echo 'set eth.xnetmask "255.255.255.0"' | nc -G1 100.100.33.111 7115

You can verify the network configuration with the following command:
echo 'get eth' | nc -G1 100.100.33.111 7115

It should now look similar to this:

eth : {		\
	ip : "",	\
	netmask : "",	\
	broadcast : "",	\
	gateway : "",	\
	mtu : 1500,	\
	xip : "172.16.0.222",	\
	xnetmask : "255.255.255.0",	\
	xbroadcast : "172.16.255.255" 	\
}

You can now set the subnet mask of the 10GbE interface your macOS network configuration to 255.255.255.0

If you do not own that device, please don’t forget to reset it either through

echo 'set eth.xnetmask "255.255.0.0"' | nc -G1 100.100.33.111 7115

or a factor reset:
echo 'iload' | nc -G1 100.100.33.111 7115
