The fields that can be configured are described below:
Parameter Description
Unit
Select the Switch unit that will be used for this configuration here.
From Port - To Port
Select the range of ports that will be used for this configuration here.
Announce Interval
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.
Announce Receipt Timeout
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.
Delay Mechanism
Select the delay mechanism here. Option to choose from are:
• E2E - This indicates that the port is configured to use the delay request-
response mechanism.
• P2P - This indicates that the port is configured to use the peer delay
mechanism.
Delay 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.
Pdelay Request Interval
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.
Synchronization Interval
Enter the synchronization interval value here. This specifies the mean-time
interval between successive synchronization messages. In line with the IEEE
