DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide To view the following window, click System > PTP (Precise Time Protocol) > PTP Boundary Port Settings, as shown below: Figure 3-31 PTP Boundary Port Settings Window The fields that can be configured are described below: Parameter Unit From Port - To Port Announce Interval Announce Receipt Timeout Delay Mechanism Description Select the Switch unit that will be used for this configuration here. Select the range of ports that will be used for this configuration here. Enter the announce interval value here. This specifies the mean-time interval between successive announce messages, referred to as the announce interval. In line with the IEEE 1588 protocol, the value of the announce interval is represented as the logarithm to the power of 2 of this time measured in seconds. The range is from 1 to 16 seconds. Enter the announce receipt timeout value here. This specifies the announce interval number that has to pass without receiving an announce message before the ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES event. This value is multiplied by the announce interval value and is equal to the interval time of the announce receipt timeout. The range is from 2 to 10. Select the delay mechanism here. Option to choose from are: • E2E - This indicates that the port is configured to use the delay requestresponse mechanism. • P2P - This indicates that the port is configured to use the peer delay mechanism. Delay Request Interval Pdelay Request Interval Enter the delay request interval value here. This specifies the permitted mean time interval between successive delay request messages which are sent by a slave to a specific port on the master. This value is determined and advertised by the master. In line with the IEEE 1588 protocol, the value of delay request interval shall be an exponent of 2. In addition, this interval must be an integer with the minimum value being the sync-interval, and the maximum value being 32 times the sync-interval value. If the sync-interval is half a second and the delay request interval is 0, then the permitted time interval between successive delay request messages will be automatically adjusted to one second. The range is from 0 to 5. Enter the peer delay request interval value here. This specifies the permitted mean-time interval between successive peer delay request messages. In line with the IEEE 1588 protocol, this value must be represented as the logarithm to the base of 2 of this time, measured in seconds. The range is from 1 to 32 seconds. 34
