[ovs-discuss] 回复： help: about ovs bond configure

[Alex Wang]

I could not reproduce the issue with both end having lacp-time=fast...

After checking your 'ovs-appctl lacp/show' output, I saw that your physical
switch was config'ed with lacp-time=slow...  That's why you have the delayed
failover...

Thanks,
Alex Wang,
