What is communication process of NTP server when NE40 is under different mode?
1. In C/s mode, the user need configure ntp unicast-server x.x.x.x at client. Dynamic connection is established at the client, but the server only passively responds request packet of the client and not set up connection.
2. In peer mode, the user need configure ntp unicast-peer x.x.x.x at active equivalent side. Static connection is set up at active equivalent side. When passive equivalent side receives the ninth packet of active equivalent side, dynamic connection is set up if it passes authentication.
3. In multicast mode, the user configures ntp multicast-server x.x.x.x at the interface of multicast server. Static connection is set up on the server. The user also need configure ntp multicast-client x.x.x.x at multicast client. There is no need to set up static connection. Dynamic connection is set up when it receives the packet from multicast server.
4. In broadcast mode, the user configures ntp broadcast-server at the interface of broadcast server. Static connection is set up on the server. The user also need configure ntp broadcast-client at broadcast client. Dynamic connection is set up when it receives the packet from broadcast server.
