I now have a 88E6352 to test your series on. Unfortunately, it doesn't really work. Here is what I did. 1. Gave one of the external switch ports an address (ifconfig ext0 192.168.1.111) 2. Ran ptp4l with option 'free_running 1'. When I run with Layer2 transport and the switch as master, it seems to work. Any other combination of role + transport fails. | Switch Role | Tranport | Result | |-------------+----------+------------------------------------------------| | master | UDPv4 | no Delay_Resp appear at slave | | master | UDPv6 | no Delay_Resp appear at slave | | master | layer2 | seems okay | | slave | layer2 | Announce messages not getting through to host? | Have you tested any of this? Do I need some special switch configuration first? Thanks, Richard
