l If the AES67 IP address on the transceiver changes, the device will reboot. This may
take up to 5 minutes.
7.8 General network and switching rules
The following table lists general system and switch requirements for small, medium and large
configurations.
System size Configuration Switch requirements
Small/medium Clear-
Com only*
1 - 30 IPTs
Up to three layer-2 hops between the
PTP master and IPTs (must not trunk
network with other VLANS)
Clear-Com AES67 traffic only
125 µs packet time
DiffServ QoS
IGMP Snooping
IGMP Querier
*These figures are for guidance only; or instance: even a small system would require PTP-
aware switches if the set up involved using more than 3 switches between the master clock
and slave.
Large Clear-Com only
10 to 30 IPTs
Up to three layer-2 hops between PTP
master and IPTs
Clear-Com AES67 traffic only
125 µs packet time
DiffServ QoS
IGMP Snooping
IGMP Querier
PTP aware transparent
and/or boundary clocks
Mixed media with
FreeSpeak II*
PTP profile is defined by existing
network equipment
PTP GM is a dedicated device (Likely a
GPS Master clock)
Either 125 µ or 1 ms packet time
1 + IPTs
DiffServ QoS
IGMP Snooping
IGMP Querier
All switches must be
PTP aware
*When setting up mixed media with Freespeak, Clear-Com recommends isolating the
FreeSpeak wireless network using a second E-IPA card to reduce setup complexity
