Hellow,
Trying to make this query a bit simple:
When *ClockClass* is set to 248, ptp4l, currently, goes into Ordinary
Clock(OC) mode. By that, it can switch to either Leader or Follower based
on availability of GM in the domain.
However, during some usecases, I would like to inhibit Slave state when
clockClass is set to 248.
To achieve this, I'm looking for a flag which can be set in the config file
to inhibit slave state. Does such a flag exist?
Thank you,
Regards,
Guru
