Parameter
Description
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
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 2 seconds. Select the
Half Second
option to set 0.5 seconds as this value.
