"\"A tmnxPtpPortEntry contains configuration pertaining to PTP on a specific Ethernet port. Rows in this table may be created and destroyed by SNMP Set operations on the object tmnxPtpPortRowStatus. Each row corresponds to PTP transport directly over a specific Ethernet port, as described in IEEE 1588-2008, Annex F. Rows may only be created corresponding to Ethernet ports. Each row must have a corresponding row in tmnxPortTable, with tmnxPortClass equal to one of the Ethernet port classes. Rows may be created corresponding to Ethernet ports configured for no encapsulation protocol, 802.1Q encapsulation ('dot1q'), or 802.1ad encapsulation ('qinq'). The tmnxPortEncapType object for the corresponding row in tmnxPortTable may be either 'nullEncap (1)', 'qEncap (2)', or 'qinqEncap (10)', respectively. Regardless of the configured encapsulation protocol, PTP packets are always transmitted 'raw', without any VLAN tags. Rows may not be created when tmnxPtpClockProfile is set to 'g8265dot1-2010 (1)'. If capable, the Ethernet port will timestamp PTP event packets at the physical port, between the Ethernet Media Access Control layer and the physical layer, corresponding to reference point 'A' in IEEE 1588-2008, Figure 14. If not, all PTP event packets transported over the port will be timestamped by the operating system kernel on the CPM card, corresponding to reference point 'B' in IEEE 1588-2008, Figure 14. Timestamping PTP event packets at the physical port requires the MDA to be configured for Synchronous Ethernet operation. Specifically, tmnxMDASynchronousEthernet must be set to 'enabled (1)'. When the user creates a PTP port entry, if the MDA supports synchronous Ethernet operation, and the MDA is not already configured for synchronous Ethernet operation, the system will configure the MDA for synchronous Ethernet operation. In order to delete an entry, tmnxPtpPortAdminState must first be set to 'outOfService (3)'.\"",
