Another useful tool is the button labeled ''iPerf." This is a built-in throughput test for all of the zones in the system. When
iPerf is selected, the system will run a test across all zones that measures the available throughput to each of the zones,
as shown in Fig. 168. The results appear as: green, meaning good throughput; yellow, meaning marginal but still accept-
able; and red, meaning not good enough to support necessary audio streaming. The result to be concerned about is red . If
a zone result is red, the solutions are to move the zone to a better location, wire it directly to the network, try 5 GHz com-
munication as opposed to 2.4, see section 4.1 zones page 20, or add an additional Gateway for additional Wi-Fi coverage .

6.5 Advanced Network Management

A popular practice is to prioritize home network traffic by creating VLANs (Virtual Local Area Networks) to provide better
performance for streaming audio and video. This work should only be done by a network administrator. The practice uses
configurable network switches that allow specific ports to be grouped for their specific VLAN communication. Each of the
VLANs are considered broadcast domains. The concept of broadcast domains is very important to proper communication
among the components of the Nuvo Player Portfolio System. For all zones to communicate properly they must be on the
same broadcast domain. Make sure that the switch ports being used for the Nuvo Player Portfolio System are operating on
the same VLAN.
Another potential issue with zone communication can be the way in which port security has been configured. Since the
components of the system are continually sending packets of information back and forth, it is important that the switch
ports being used are open to all network traffic. If they are not, this will impede the necessary communication across the
entire system.
On any managed switch, speed and duplex must be set on the ports being used by the Nuvo Player Portfolio System to
auto negotiate. This is the way in which the zones communicate. The common mistake would be to set the ports to gigabit
communication which will cause a communication mismatch with the zones.
