Given a non-PTP switch (e.g. no hardware support for time stamping), how can one make it to be as close as possible to a PTP compliant switch. I am thinking here to configure the switch such that the PTP traffic has the highest priority (which is kind of super basic configuration). Can you please suggest other possible configurations?
PS: I am aware that in general such configurations are hardware dependent given the switch capabilities. Therefore I am looking for all kind of crazy options.
