clockIdentity
The clockIdentity identifies a clock. The
clockIdentity is an 8-octet identifier created from the
Ethernet MAC address in the format:
First 3 octets – most significant octets of MAC
address
Next 2 octets – have values FFh and FEh
respectively
Last 3 octets – least significant octets of MAC
address
The clockIdentity is used as a tie-breaker for the
master clock.
