NTP Configuration Commands

To protect unused sockets against attacks by malicious users and improve security, H3C S3600 series
Ethernet switches provide the following functions:
UDP port 123 is opened only when the NTP feature is enabled.
UDP port 123 is closed as the NTP feature is disabled.
These functions are implemented as follows:
Execution of one of the ntp-service unicast-server, ntp-service unicast-peer, ntp-service
broadcast-client, ntp-service broadcast-server, ntp-service multicast-client, and ntp-service
multicast-server commands enables the NTP feature and opens UDP port 123 at the same time.
Execution of the undo form of one of the above six commands disables all implementation modes
of the NTP feature and closes UDP port 123 at the same time.
