Hi there,
Wireshark does not seem to decode tlvType at the tail of Signalling Message
messages. See 1588-2008 16.1.4.1 for reference.
I enclose a trace an the right decoding for those sub-fields.
10.222.222.22 is master
10.71.3.3 is slave
Sample 1
--------
Line 103 - Signalling message
>From tlvType (last field decoded) and onwards...
Raw string: ...04 00 06 B0 01 00 00 01 2C
00 04 tlvType = Request Unicast Transmission
00 06 lengthField = 6
B0 messageType = 0 = Announce (Note: Unicast requested for Sync messages,
see 13.3.2.2)
01 reserved
00 00 logInterMessagePeriod = 2^0 = 1 second
01 2C durationField = 12C'h= 300 seconds
Sample 2
--------
Line 105 - Signalling message
>From tlvType (last field decoded) and onwards...
Raw string: ...00 04 00 06 00 FA 00 00 01 2C
1588-2008 16.1.4.1
00 04 tlvType = Request Unicast Transmission
00 06 lengthField = 6
00 messageType = 0 = Sync (Note: Unicast requested for Sync messages, see
13.3.2.2)
FA reserved
00 00 logInterMessagePeriod = 2^0 = 1 second
01 2C durationField = 12C'h= 300 seconds
Any doubt, don´t hesitate in asking.
Alex
