AES67/SMPTE 2110 Network and Switch Requirements

SMPTE 2110 audio relies on a well-regulated PTP network. Therefore, you will need to take care with your network setup before trying to receive or transmit AoIP.

In the first case you need:

• IGMP snooping and a querier to allow multicast traffic to be routed through the network in a controlled manner

• QoS: PTP and audio packets must be set at a high priority (DSCP value, priority setting and position in switch queues).

• AES67/SMPTE 2110 interface ports on the E-IPA card must have a static IP address

• AES67/SMPTE 2110 streams must be in the multicast IP range (239.0.0.0 – 239.255.255.255)
