The aluPtpUcMasterEntry contains the information pertaining to the Unicast Master Table as described in the IEEE Std 1588-2008 Section 17.5. Entries within this table represent potential masters (for boundary clocks and slave-only ordinary clocks) or slaves (for ordinary clocks that are not slave-only). Genererically entries in this table are referred to as peers. Rows are created and destroyed based on the aluPtpClockType and aluPtpClockSlaveOnly values. The number of master/peer entries is based the aluPtpPortTable::aluPtpPortNumPeers defined for the PTP port indexed by aluPtpPeerClockIndex and aluPtpPeerPortIndex.
