7.4 Interaction PTP and SNTP
According to PTP and SNTP, both protocols are permitted to coexist in one
network. However, since both protocols influence the system time of the
device, situations may occur in which both protocols compete with each
other.
Note:
Configure the devices in such a way that each device receives the
system time exclusively from one source.
If you want the switch to receive the system time using PTP, enter the
external server address 0.0.0.0, and do not accept any SNTP broadcasts
when performing the SNTP client configuration.
If you want the switch to receive the system time using SNTP, make sure that
the best clock is connected to the SNTP server. Thus, both protocols receive
the time from the same server. The example
plication.
