Question
: In a Point to Point environment how should the MX4 and MXE+ be configured?
Answer:
First, on the networking front be sure that both the MX4 and MXE+ are set for
static IP with addresses on the same subnet. ZeeVee would recommend RTP for P2P
installations. RTP has more timing and synchronization information built into the protocol.
Question
: In a network environment how best should the MX4/MXE+ be configured?
Answer:
In a network environment, the ZyPerMX4 should be configured for UDP/RTP and
multicast.
Question
: How does channel beaconing work?
Answer:
The ZV channel beacon uses the 239.13.1.19 multicast address. The MX4 uses
this address to publish its channels across the network. In a single layer 2 network this
should always work. In a routed layer 3 network, this multicast address needs to be added
to the router’s forwarding table explicitly. By default, routers will not forward this address.
The actual command to do this varies by router.
Question:
What other Network protocols are required to support the ZyPerMX4/MXE+?
Answer:
For an installation of more than a couple of MX4 sources, the layer 2 Ethernet
switch needs to be a smart switch that supports IGMP and multicast traffic management
ands vary by vendor.
Question:
Should every MX4 stream in the system be configured with a different multicast
address? (UDP and RTP streaming)
Answer
: Each MX4 stream needs to be configured for a different multicast address for
proper stream bandwidth management. Network switches filter based on the IP multicast
address only. If multiple MX4 streams are configured with the same multicast address with
different ports, all the packets with that multicast address will be forwarded to any MXE+’s
tuned to any one of those channels. This will overwhelm the Ethernet processing on the
MXE+ and cause video artefacts.
Question:
What is the range of multicast addresses that can be used by the MX4?
Answer:
The full range of multicast addresses is from 224.0.0.0 to 239.255.255.255
