TX/RX PTP Message Count/Rate
Gives the transmitted/received count and average rate for each PTP
message, and the total count for all messages.
Note:
In the case where messages are lost while the Receipt Timeout is set to a
large value (slow communication), the last valid recorded rate value will
be preceded with “
<
” to indicate that the reception rate is not stable. This
applies to
Delay Resp
,
Announce
,
Sync
, and
Follow UP
.
Note:
When the rate is above 150 message/s, “
> 150
” is displayed.

The rate value corresponds to an average rate because these messages are only
transmitted/received when negotiating or renewing the lease with the Grand Master
clock. If the connection with the Grand Master Clock was already established when the
test is started, the
0
value is displayed. However, the value becomes available with the
next lease renewal which happens every 150 seconds.
