•Enable Receive Unicast Servers Updates — Defines whether or not the device polls the SNTP server for Unicast server time information. If the Enable Receive Broadcast Servers Updates, Enable Receive Anycast Servers Updates, and Enable Receive Unicast Servers Updates fields are all enabled, the system time is set according the Unicast server time information. The possible values are:

–Enable — Enables the device to receive Unicast server updates.

–Disable — Disables the device from receiving Unicast server updates.

•Enable Poll Unicast Servers — Defines whether or not the device sends SNTP Unicast forwarding informa- tion to the SNTP server. The possible values are:

–Enable — Enables the device to receive Poll Unicast server updates.

–Disable — Disables the device from receiving Poll Unicast server updates.

2.Define the Poll Interval, Enable Receive Broadcast Servers Update, Enable Receive Anycast Servers Update, Enable Receive Unicast Servers Update, and Enable Poll Unicast Servers fields and select at least one of the Enable fields.
