The fields that can be configured are described below:
Parameter Description
Unit
Select the switch unit to configure.
From Port / To Port
Select the port range to use for this configuration.
Announce Interval
(1-16)
Click the radio button and enter the mean time interval between successive announce
messages. Referred to as the announce interval. In line with the IEEE1588 protocol,
the value of the announce interval is represented as the logarithm to the base 2 of this
time measured in seconds. The entered value should be 1, 2, 4, 8, or 16. If entered an
invalid number, it will be automatically adjusted to allow the bigger and closest value.
The default value is 2 seconds.
Announce Receipt
Timeout (2-10)
Click the radio button and enter the announce interval number that has to pass without
receiving an Announce message before the occurrence of the
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES event. This value multiplied by the
announce interval value is equal to the interval time of the announce receipt timeout.
The range is from 2 to 10.
Delay Mechanism
Use the drop-down menu to specify the mechanism for measuring the propagation
delay time of an event message.
E2E - The port is configured to use the delay request-response mechanism.
P2P - The peer delay mechanism.
The default is E2E.
Delay Request
Interval (0-5)
Enter the permitted mean time interval between successive delay request messages
which are sent by a slave to a specific port on the master. This mean time interval
value is determined and advertised by a master.
Pdelay Request
Interval (1-32)
Enter the permitted mean time interval between successive pdelay_request
messages.
Synchronization
Interval (1-2)
Enter the mean time interval between successive Sync messages. Referred to as
syncInterval. Tick the Half Second check box to have the 0.5 second of syncInterval.
Click the Apply button to accept the changes made.
