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
