This parameter reports the link’s status if it has been loaded. A Reset (S.10.002) is
required to load any changes.
6.1.5 Menu 11 – Synchronization
This Ethernet interface will be preferred as the grandmaster over others with higher
preferred values or none specified. A value of zero will ensure that the Ethernet
interface will not become grandmaster (making the Ethernet interface act as an IEEE
1588 slave device only). If more than one Ethernet interface has the same preferred
value only one will be chosen as the grandmaster using the IEEE 1588 BMC algorithm.
The parameter does not guarantee that the Ethernet interface will become grandmaster
but a value of zero guarantees that the Ethernet interface will not become a
grandmaster.
Specifies the clock domain for the Ethernet interface to act as a grandmaster clock.
This parameter displays the MAC address, as a 64-bit hexadecimal value, of the
