[Linuxptp-users] PTP packets not being acted upon by RHEL 7 server

[Taber, A. <ala...@lm...>]

I have a SecureSync 9400 GrandMaster clock that is appropriately putting out PTPv2 Sync and Announce packets (verified by Wireshark listening on a different network node). I have run tcpdump -i enp9s0 -v to check to see that the packets are getting through to my RHEL 7 server, and they are showing up.

Yet, when I run ptp4l -i enp9s0 -m, I get the following:

Selected /dev/ptp1 as PTP clock
driver changed our HWTSTAMP options
tx_type 1 not 1
rx_filter 1 not 12
port 1: INITIALIZING to LISTENING on INITIALIZE
port 0: INITIALIZING to LISTENING on INITIALIZE
port 1: link up
port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
selected best master clock 0cc47a.fffe.acbaf7


at this point I can see sync and announce packets on the network from both my GrandMaster clock and this RHEL 7 server.

What indicators should I be looking at to see why the local ptp daemon isn't listening to the packets the server is receiving?

Thanks in advance for any insight you can share.

Best regards,
