No problem. The text dump shows everything. You have a very stange
network that is unfamilar to me. I'm not sure I can help you at
all...
The log shows:
ptp4l[1208613.181]: port 1: new foreign master 001b21.fffe.df71ab-8193
ptp4l[1208617.145]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[1208617.181]: selected best master clock 001b21.fffe.df71ab
Notice the port ID? But the text dump shows:

Things wrong here:
~~~~~~~~~~~~~~~~~~
1. The Source MAC Sprecher_05:00:c4 (in the summary)
is not the same as Source: XXXXXX_01:02:03 (00:00:00:01:02:03)
2. There is a VLAN tag. linuxptp never adds VLAN tags!
And look at the response:

~~~~~~~~~~~~~
1. ClockIdentity: 0x001b21fffedf6f6c with SourcePortID: 1 does not
match the selected master 001b21.fffe.df71ab-8193
2. the VLAN tag. I didn't see the message ("raw: switching to VLAN mode")
in your log output.
Maybe this capture comes from a man in the middle?
If so, try tcpdump/tshark on the actual slave node instead. It could
very well be that the peer delay responses are not arriving at the slave.
HTH,
