3.8.1 Network setup for the FreeSpeak II and FreeSpeak Edge transceivers
Bear in mind the following network considerations. For more information, refer to the Clear-
Com network recommendations document.
l Clear-Com recommends that AES67 traffic has its own dedicated network or VLAN.
l If there is no DHCP server, AES67 connections will use the link-local range of IP
addresses (169.254.XXX.XXX).
l When configuring an AES67 network, the network switch needs to have DiffServ
Quality of Service (QoS) switched on.
l Internet Group Management Protocol (IGMP) snooping needs to be switched on, with at
least one IGMP querier.
l The network must be 1Gbps. A 100Mbps network will not support the amount traffic
the card can generate, and will not deliver the required PTP accuracy.
l The Multicast enabled switch must be ON.
l Try to keep the number of layer 2 hops between PTP master and slave (for example, IP
Transceiver) as low as possible (no more than three). If there are more than three, you
require switches that support PTP. You may also have to use transparent or boundary
clocks.
l Use DHCP (the default setting) for fast and easy setup of the devices. If no DHCP server
is present, IPTs will self-assign an IP address in the link-local IP range.
The screen below shows the E-IPA-HX card properties screen.
Note: If you need to use static IP addressing for your transceivers, see Static configuration in this
document.
