This property uniquely identifies the clock in the network.

The Clock ID is formed by taking the MAC address assigned to the clock and mapping it to an array of eight bytes, according to rules in the IEEE Std 802 EUI-48 standard. The best master clock algorithm (BMCA) uses this property as a tie-breaker among clocks that would otherwise be equal.

The Clock ID is returned as a string of eight octets. Each octet consists of two hexadecimal (0-9, A-F) digits. The octets are separated by colon. For example, 00:80:2F:AB:CD:EF:00:01

For the Protocol of IEEE Std 802.1AS-2011, this property corresponds to the clockIdentity parameter as described in 14.2.1 of IEEE Std 802.1AS-2011.
