DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide The fields that can be configured in PTP Global Settings are described below: Parameter PTP State PTP Mode PTP Transport Protocol Description Select to enable or disable the PTP feature here. When the PTP function is enabled, the Switch port will add residence time to correct the field. When the PTP function is disabled, all Switch ports will forward the PTP packets according to the multicast filtering configuration. Select the PTP mode here. Options to choose from are:  Boundary - Specifies the Switch as a Boundary Clock.  P2P Transparent - Specifies the Switch as a Peer-to-Peer Transparent Clock. This is a clock that provides Precision Time Protocol (PTP) event transit time information and also provides corrections for the propagation delay of the link. The link, in this case, is connected to the port that is receiving the PTP event messages. Ports on peer-to-peer transparent clocks use the peer delay mechanism to calculate the propagation delay between PTP ports.  E2E Transparent - Specifies the Switch as an End-to-End Transparent Clock. An End-to-End Transparent Clock supports the use of an end-to-end delay measurement mechanism between the slave clock and the master clock. Ports on end-to-end transparent clocks are independent of propagation delay mechanisms. Select the PTP transport protocol here. Options to choose from are:  Ethernet - Specifies the transport protocol of PTP as IEEE802.3 Ethernet.  UDP - Specifies the transport protocol of PTP as UDP over IPv4.

The fields that can be configured in PTP Clock Domain Settings are described below: Parameter Unit PTP Clock Domain Number PTP Clock Domain Name Description Select the Switch unit that will be used for this configuration here. Enter the PTP clock domain number here. All PTP messages, data sets, state machines, and all other PTP entities are always associated with a particular domain number. The range is from 0 to 127. Enter the PTP clock domain name here. The name is used for user reference. This name can be up to 32 characters long. Click the Apply button to accept the changes made. The fields that can be configured in PTP Boundary Clock Settings are described below: Parameter Priority 1 Priority 2 Description Enter the PTP boundary clock Priority 1 value here. The priority 1 attribute is used in the execution of the Best Master Clock algorithm. A lower value takes precedence. Zero indicates the highest precedence. The range is from 0 to 255. Enter the PTP boundary clock Priority 2 value here. The priority 2 attribute is used in the execution of the Best Master Clock algorithm. A lower value takes precedence. In the event that the BMC algorithm fails to order the clocks based on the values of priority 1, the clock's class, and the clock's accuracy; the priority 2 attribute will allow the creation of lower values compared to the other devices. Zero indicates the highest precedence. The range is from 0 to 255. Click the Apply button to accept the changes made. 26
