The time can be synchronized only after the management node is consistent with the NTP server. If the management node slowly synchronizes time with the NTP server and the time is inconsistent, the product node cannot automatically synchronize time with the management node.If you do not configure an NTP server, the management node functions as the clock source by default.If multiple NTP servers configured on the management plane become invalid, the management node cannot synchronize time from the NTP servers, and the product nodes will no longer synchronize time from the management node. The management node then synchronizes time with the selected NTP server. If the active NTP server fails, the management plane will select an available NTP server from the standby NTP servers within 15 minutes.After the active NTP server is configured, the management node will first synchronize time from the NTP server, time on all product nodes will be synchronized from the management node.Only one active NTP server can be configured and the active NTP server is mandatory. A maximum of 10 NTP servers can be added on the management plane.This ensures time information integrity and protects servers from being attacked during time synchronization. NTP-based time synchronization operations include identifier authentication and information integrity authentication.
