The VLX Series has the ability to go the distance. While regular CAT 5e will go 100m
(330ft), CAT 6 and 6A can go much further. Below we have tested the following cabling
from West Penn and the results of the testing with 4K video. Please note if using a
different brand cable when exceeding the industry standard 100m (330ft) we highly
recommend verifying the results first prior to installation as not all cables perform the
same.
Cat 5e UTP (Unshielded): 100m (330ft)
Any brand on the market made to Category 5e or better specification.

NETWORK SWITCHES
The VLX will work with most non-blocking, IGMP with IGMP Snooping, 8192 or better
Jumbo/MTU Packet 1G network switch. Layer 3 will allow more control, however, Layer
2 will work as well. It is highly recommended to communicate with the representative of
the desired network switch brand to confirm configuration and capabilities. Below are
some models that have been tested with the VLX Series.
1.1 Switch Speed
The VLX Series requires the switch to be a 1GbE.
VLX Series technology is used to transmit visually lossless 8:1 compress video up to 4K
along with other AV signals such as audio, USB and control signals. For video alone, it
means raw bandwidth of about 850Mbps for 4K and that is just for audio and video. It is
therefore easy to understand why the VLX requires 1GbE network switches.
1.2 Packets Routing
To enable the transmission of a source to multiple destinations, VLX devices make use
of Multicast. The default behavior of layer 2 Ethernet switch is to broadcast those
packets which mean that every packet will be transmitted to all possible destinations.
This is why any network switch used with VLX Series has to support IGMP Snooping.
VLX end points use IGMP protocol to assign the end points into multicast groups and
the router uses IGMP snooping to efficiently route multicast packets only to receivers
that want to receive them.
Many switches have the IGMP Snooping feature disabled by default and manual
configuration is required. Often, a simple check mark near “Enable IGMP Snooping” is
the only thing needed to enable IGMP Snooping.
However, the implementation of IGMP Snooping is vendor specific and additional
configuration is often needed.
An Ethernet switch can be informed that a device wants to leave a multicast channel by
sending it a IGMP LEAVE GROUP packet. Once received, the time it takes for the
switch to apply the new configuration may vary from one switch to the other. Most
switches implement and include FASTLEAVE configuration option. When enabled, it
takes much less time for a particular port to leave a multicast group to assign the port to
a different multicast group. The end results are a noticeably shorter video switching
time. Aurora recommends to always enable the FASTLEAVE option when available.
1.3 Ethernet Switch Configuration
The following list includes all network switch configuration options that Aurora
Engineers have come across so far. Look for these or similar options when configuring
your switch.
1. Enable IGMP Snooping
a. Must be enabled
2. Enable IGMP Snooping on VLAN 1
a. Must be enabled when all ports default to VLAN1

IMPORTANT: This following is presented as informational examples. Switch hardware, software, firmware of these devices may
change. Always consult your switch manufacture to verify compatibility before purchase, and contact the manufacturer for setup and
troubleshooting assistance. ALWAYS pre-stage / test your system for proper configuration and operation prior to site installation.
Network Guide
3. Filter/Drop unregistered Multicast traffic
a. If not applied, the behavior of the switch will be to broadcast multicast packets
if the switch has no known destination for that packet.
b. Must be enabled if found
4. Unregistered Multicast Flooding
a. Must be disabled if found
5. Filter Unregistered Multicast (different wording than number 4 above)
a. Must be enabled if found
6. Enable IGMP Query
7. Enable IGMP Query on VLAN1
8. Set IGMP Version to IGMP V2
a. Must be set if found
9. Enable FASTLEAVE on port X
a. This is optional. Should be enabled, if found
10. Enable FASTLEAVE for VLAN1
a. This is optional. Should be enabled if found
11. Jumbo Packets should be standard function but if not it must be enabled.
a. This is must be enabled. Some switches refer to Jumbo packets as MTU size
and must be set to 8192 or larger. Others will be a simple check box.
1.4 PoE (Power over Ethernet)
The VLX Series uses around 6 watts of power, however, the PoE is unclassified for up
to 12.9 watts (15.4 Watts Total) as the USB on the VLX can supply up to 5 watts. When
selecting a PoE switch always make certain the power supply of the PoE switch is
proper to the port count (15.4W x qty of ports). For example, a 24 port PoE switch must
have at least 369.6 Watts (24 at 15.4W) for it to properly supply all 24 VLX devices.
Some switches can only supply a certain amount of ports with PoE. If it is necessary to
use a particular switch, then PoE injectors for the remaining ports can be used or the
local power supply for the VLX but you may need to disable the detection of the PoE for
those ports in the Ethernet switch.

1.5 Ethernet Switch Models with Performance Issues
To follow are reported or tested network switches with issues. It is always recommended
to check with manufacturer in the event firmware has resolved the reported issues.
Cisco SG300
1. The ability to handle multicast request is insufficient. It takes a long time for switches
to start forwarding multicast packets to the corresponding ports after receiving IGMP Join
messages. The switches that act as extended switches in a cascade network have more
obvious problems. If they receive more multicast requests in a short period, some of the
requests will be discarded because switches are unable to deal with them in time,
resulting in Rx switch failure.
2. Multicast forwarding synchronization is poor. There is an issue when copying and
forwarding the same multicast packet to the multiple host ports. The time for each port
to receive multicast packets may have a difference of 20ms or more. As a result, the
same source on different Rx units may be out of sync.
In summary, SG300 can be used in single switch networking and locations where high
multi-screen synchronization is not required. If you require a cascaded network,
multi-view or video wall, we would not recommend this model.
1.6 Multicast IP & Ports That Must Not Be Blocked
To discover the device on the network the VLX protocol works as follows. Each VLX device
when booted up will listen to port 3333 of multicast IP address 225.0.0.1 If a request is
received on this port, the VLX device will send its information as reply. If a VLX device
needs to find all other devices in the network, it runs an internal process same as
node_list. This process will send a request to multicast IP 225.0.0.1, port 3333. All the
VLX devices will respond to this request and based on that the connected encoders list is
shown by each decoder.
Now in case of Multicast switches to forward any request received at port 225.0.0.1 to the
VLX device, it needs to join to that particular IP address. For this each VLX device will
send the IGMP host membership report packet (type 0x16) at 5s interval to the
multicast IP address 225.0.0.1.
Similarly, the video data is also send by the encoder as multicast packets to the
destination address determined by its host ID. For example, the encoder with host ID
0009 will send the video packet to multicast IP 225.0.100.9. Each decoder who want to
connect to encoder 9 will listen to this particular multicast IP. IGMP packets are sent at 5s
interval by the encoders and decoders.

CONFIGURATIONS
Switch Login & Connections
Login
You must first log onto the switch with administrator right. Follow the switch manufacturer
manual to do so. It will also give you the default Admin password.
Console Port
Some manufacturers use RS-232 / “Console port” for switch configuration and dedicated
console cable which is different from a standard Cat X (RJ45) cable.
Ethernet
Other manufacturers go through standard 1Gbe compatible port for switch configuration. If
this is the case, the manufacturer will give you the default “IP Address” of the switch. Make
sure your network adaptor has an IP Address in the same network.
Depending on login method above, switch configuration will be done either through a Web
Browser or a Telnet Client.
