DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide A clock that provides Precision Time Protocol (PTP) event transit time information 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. 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. Example This example shows how to configure the Switch as a Peer-to-Peer Transparent Clock. Switch#configure terminal Switch(config)#ptp mode p2p-transparent Switch(config)# 87-7 ptp p2p-transparent pdelay-req-interval This command is used to configure the PDelay Request message attribute for the message interval of the P2P transparent clock. Use the no form of this command to revert to the default setting. ptp p2p-transparent pdelay-req-interval SECONDS no ptp p2p-transparent pdelay-req-interval Parameters SECONDS Specifies the permitted mean time interval between successive PDelay Request messages. In line with the IEEE 1588 protocol, the value of the announce interval is represented as the logarithm to the base 2 of this time measured in seconds. The value is from 1 to 32, and thus the imported value can be 1, 2, 4, 8, 16, or 32. Default By default, the value of the PDelay Request message interval is 1 second. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is used to configure the PDelay Request message attribute for the message interval of the P2P transparent clock. Example This example shows how to configure the PDelay Request message attribute for the message interval of the P2P transparent clock to 4 seconds on port 1/0/3. 1146
