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: No. Time Source Destination Protocol Length sequenceId ID Info 3 0.042398971 Sprecher_05:00:c4 LLDP_Multicast PTPv2 72 25635 150 Path_Delay_Req Message Ethernet II, Src: XXXXXX_01:02:03 (00:00:00:01:02:03), Dst: LLDP_Multicast (01:80:c2:00:00:0e) Source: XXXXXX_01:02:03 (00:00:00:01:02:03) Address: XXXXXX_01:02:03 (00:00:00:01:02:03) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) .... ...0 .... .... .... .... = IG bit: Individual address (unicast) Type: 802.1Q Virtual LAN (0x8100) 802.1Q Virtual LAN, PRI: 0, DEI: 0, ID: 150 000. .... .... .... = Priority: Best Effort (default) (0) ...0 .... .... .... = DEI: Ineligible .... 0000 1001 0110 = ID: 150 Type: PTPv2 over Ethernet (IEEE1588) (0x88f7) Precision Time Protocol (IEEE1588) ClockIdentity: 0x000000fffe010203 SourcePortID: 0 sequenceId: 25635 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: No. Time Source Destination Protocol Length sequenceId ID Info 4 0.042448275 IntelCor_df:6f:6c LLDP_Multicast PTPv2 72 25635 150 Path_Delay_Resp Message Ethernet II, Src: IntelCor_df:6f:6c (00:1b:21:df:6f:6c), Dst: LLDP_Multicast (01:80:c2:00:00:0e) Source: IntelCor_df:6f:6c (00:1b:21:df:6f:6c) Address: IntelCor_df:6f:6c (00:1b:21:df:6f:6c) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) .... ...0 .... .... .... .... = IG bit: Individual address (unicast) Type: 802.1Q Virtual LAN (0x8100) 802.1Q Virtual LAN, PRI: 0, DEI: 0, ID: 150 000. .... .... .... = Priority: Best Effort (default) (0) ...0 .... .... .... = DEI: Ineligible .... 0000 1001 0110 = ID: 150 Type: PTPv2 over Ethernet (IEEE1588) (0x88f7) Precision Time Protocol (IEEE1588) ClockIdentity: 0x001b21fffedf6f6c SourcePortID: 1 sequenceId: 25635 requestingSourcePortIdentity: 0x000000fffe010203 requestingSourcePortId: 0 Things wrong: ~~~~~~~~~~~~~ 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.
