And:
I'm using G8316 as swtich with ptp transparent enable and Mellanox 354 adapter.
Ports using LACP bonding and trunk.
First: Server A ptp4l -m -l 7 -i xxxx -i xxxx -S
I can capture ServerA boardcast package in ServerB, And ptp counter show non-zero in G8316 switch. That's mean ptp package delivered, Which is good.
Then: Server B ptp4l -m -l 7 -i xxxx -i xxxx -S -s
Server B can't find server A, And use local clock as best master
Question:
- Why Server A say
master sync timeout - Why Server B stubborn thinkg local clock is best master
I also try set priority with conf file master is 0, slaves is 255. No working.
