APPENDIX
d. If there are multiple multicast Master Clocks on the network, the PTP Mod-
The Master Clock selected by the BMC algorithm as the Best Master Clock will
transition into the Master state to become the active Master Clock on the net-
work. It will then start to transmit Sync packets to the Slave Clocks. The other
Master Clocks will transition into the Passive state.
Enabling PTP
To enable PTP:
1. Navigate to the Top panel of the GB PTP Edit window.
2. Check the
Configuring Multicast Mode
To enter Multicast mode, perform the following steps:

ule uses the Best Master Clock (BMC) algorithm specified in the PTP Spe-
cification to decide whether or not to become the active Master Clock. The
BMC algorithm selects the Best Master Clock on the network from the fol-
lowing criteria:
i. The BMC algorithm first selects the clock having the higher Priority1
parameter (a lowest value means a higher priority).
ii. If the BMC cannot be determined from the previous parameter, the
BMC algorithm selects the clock having the higher Clock Quality
(Clock Class, Clock Accuracy, Clock Variance).
iii. If the BMC cannot be determined from the previous parameters, the
BMC algorithm selects the clock having the higher Priority2 para-
meter.
