5.3.4 Adding an NTP Neighbor

To add a new NTP peer or server neighbor configuration to those available to the switch for synchronization:

1.Select Services > Secure NTP from the main menu tree.

2.Select the NTP Neighbor tab.

3.Click the Add button.

4.Select the Peer checkbox if the SNTP neighbor is a peer to the switch (non FTP server) within the switch’s current subnet.

5.Select the Server checkbox if the neighbor is a server within the switch’s current subnet.

6.Select the Broadcast Server checkbox to allow the switch to listen over the network for NTP broadcast traffic.

The switch’s NTP configuration can be defined to use broadcast messages instead of messaging between fixed NTP synchronization resource addresses. Use a NTP broadcast to listen for NTP synchronization packets within a network. To listen to NTP broadcast traffic, the broadcast server (and switch) must be on the same subnet. NTP broadcasts reduces configuration complexity since both the switch and its NTP resources can be configured to send and receive broadcast messages.

NOTE: If this checkbox is selected, the AutoKey Authentication checkbox is disabled, and the switch is required to use Symmetric Key Authentication for credential verification with its NTP resource. Additionally, if this option is selected, the broadcast server cannot be selected as a preferred source.

7.Enter the IP Address of the peer or server providing SNTP synchronization with this configuration.

8.Select the Hostname checkbox to assign a hostname to the server or peer for further differentiation of other devices with a similar configuration.
