NTP implementation mode: multicast mode
Table 1-1 describes how the above mentioned NTP modes are implemented on an
S5600 series switch.

Configuration on S5600 switches
Client/Server mode
Configure the S5600 switch to operate in the
NTP server mode. In this case, the remote
server operates as the local time server, and
the S5600 switch operates as the client.
Peer mode
Configure the S5600 switch to operate in
NTP peer mode. In this case, the remote
server operates as the peer of the S5600
switch, and the S5600 switch operates as the
active peer.
