Prepare Network for Terra Multicast
If you are using a Terra Controller, use the following guidelines to plan your installation:
•
If you are operating on a customer network, prepare an addressing plan and review it with
your IT System Administrator. Include the following topics in the plan:
−
Use of multicast networking
−
IP address range, subnet mask, and gateway values for the controller(s) and associated
devices.
•
If the network switch is supplied, managed, and operated by the customer’s IT department,
review the following with the IT System Administrator:
−
The switch requirements including the multicast address range used.
−
The configuration information identified in the following sections.
Setting up the Switch
The most practical method for preparing a network for a Terra system is to use Layer 2 IGMP V2
Multicast management across one broadcast domain/VLAN.
Non-IGMPv2 multicast management techniques are not supported for use with Terra.
Best practice is to not have DHCP active on the Terra network. The Terra Startup Assistant
is used to assign static addresses to the Terra devices.
DHCP address management is popular for desktop PCs because they frequently migrate,
and this eliminates configuration time for IT staff. Terra Controllers, Transmitters and
Receivers are network appliances that are similar to printers and servers which do not
migrate and are better managed using static IP addresses. Use of static IP addresses also
reduces the amount of DHCP/DNS network traffic resulting in greater efficiency. A
compromise that can be used when network policies dictate use of DHCP addressing is to
reserve a block of static IP addresses for use with Terra Transmitters and Receivers and
other AV devices.
Set up the network switch with the following capabilities and features enabled:
Feature
Relevance
10G Ethernet
Switch
Clock rate per port required for the SDVoE standard.
Full 10G line rate
Full data rate supported on the network port throughout the network
switch between the backplane and all ports.
Non-blocking
design
Switch fabric or backbone of system supports sustained, uninterrupted,
full capacity 10G transport of SDVoE content inputs and outputs to all
devices.
L2/L3 Managed
Switch
Switch is programmable with VLANs, IGMPv2 multicast and data
forwarding features.
Layer 3 switches frequently include a querier.
IPv4
Addressing format used in SDVoE, future upgradable to IPv6.
IGMPv2
IGMP 2 version multicast protocols support system scalability.
IGMP Snooping
Essential multicast management activity.
IGMP Querier
Essential multicast management activity.
