Fix Recommendation

Configure NTP Servers during node adoption with the following steps:
1. Go to the "configuration object" page.
2. Enter the NTP Server IP addresses in appropriate settings fields. The SEL-2740S support primary and backup NTP servers so enter the IP address of the backup if desired so there are both primary and backup displayed.
3. Click "Submit".
4. Create NTP Flows to/from NTP server to/from node.

Check Contents

To ensure SEL-2740S NTP servers are configured do the following:
1. Log in with Permission Level 3 rights into parent OTSDN Controller.
2. Go to the "configuration object" settings page.
3. Check NTP Server IP addresses in the settings fields. The SEL-2740S support primary and backup NTP servers so enter the IP address of the backup if desired so there are both primary and backup displayed.
4. Check NTP flows for the SEL-2740S DUT and additional neighbor devices exist and are correct.

If the SEL-2740S is not configured to maintain internal system clocks with an authoritative time server, this is a finding.
