Object
row
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)'.
