Link-Local Ip Addresses - Polycom SoundStructure C16 Design Manual

Network Management
By default the system name is set to "SoundStructure System" as shown in the
next figure.
The system name is used to easily identify units and can be set with the Sound-
Structure Studio as shown in the previous figure by entering the name and
pressing the Apply button or by using the sys_name API command as shown
below.
set sys_name "Room 475B"
the system will respond with the command acknowledgement
val sys_name "Room 475B"
Now the system name has been set to "Room 475B" and that's how it will be
identified during the next time Connect to Devices is selected. Save the project
to disk with the File Save or File Save As option from SoundStructure Studio
to save the file to disk and also when working online to force the SoundStruc-
ture device to store the system name permanently.

Link-Local IP Addresses

SoundStructure devices configured for DHCP and running version 1.3 or later
firmware will default to the link-local IP address of 169.254.1.1 when there are
no DHCP servers available to provide an IP address when the SoundStructure
device powers up. The link local addressing makes it possible to connect to a
computer directly to a SoundStructure device with either a straight-through or
crossover Ethernet cable without either having to set a static IP address or
having a DHCP server available.
