I. NTP server mode
When an S3100 series switch operates in NTP server mode,
The remote server identified by the remote-ip or server-name argument operates
as the NTP time server. The S3100 series switch operates as the client, whose
clock is synchronized to the NTP server. (In this case, the clock of the NTP server
is not synchronized to the local client.)
The remote-ip argument cannot be a broadcast or a multicast address, neither can
it be the IP address of a reference clock.
II. NTP peer mode
When an S3100 series switch operates in NTP peer mode,
The remote server identified by the remote-ip or server-name argument operates
as the peer of the S3100 series switch, and the S3100 series switch operates as
the active peer. The clock of the S3100 series switch can be synchronized to the
remote server or be used to synchronize the clock of the remote server.
The remote-ip argument cannot be a broadcast or a multicast address, neither can
it be the IP address of a reference clock.
III. NTP multicast server mode
When an S3100 series switch operates in NTP multicast server mode, it can
accommodate up to 1024 multicast clients.
