Configuring PTP Profile
This chapter describes how to configure the precision time protocol (PTP) on
AES67 devices.
PTP provides time synchronization accuracy to the sub-microsecond level and
can achieve both time and frequency synchronization, with low deployment
and maintenance costs, which can substantially reduced Capex and Opex.

Type
shows current PTP protocol version. PTPv2 is a time synchronization
protocol defined in IEEE 1588 for nodes distributed across a network. With
PTP, it is possible to synchronize distributed clocks with an accuracy of less
than 1 microsecond via Ethernet networks.
■
Priority 1
: specify PTP priority 1 value when advertising the clock. The range
is from 0 to 255. The default value is 255. This value works for best master
clock selection. Lower values take precedence.
■
Priority 2
: specify the priority 2 value to use when advertising this clock.
This value is used to decide between two devices that are otherwise equally
matched in the default criteria. For example, you can use the priority2 value
to give a specific unit priority over other identical devices. The range is from
0 to 255. The default value is 255.
■
Domain
: specify PTP domain (domain 0, by default) for your device. Value
ranges from 0 to 127. Each domain is completely isolated from other
domains and can therefore be seen as different PTP networks. can only be
