1.2 NTP Implementation Mode Configuration

A switch can operate in the following NTP modes:
NTP client mode
NTP server mode
NTP peer mode
NTP broadcast server mode
NTP broadcast client mode
NTP multicast server mode
NTP multicast client mode

1.2.1 Prerequisites

When an S7500 switch operates in NTP server mode or NTP peer mode, you need to
perform configuration on the client or the active peer only. When an S7500 switch
describes how the above mentioned NTP modes are implemented on an
mode
Configure the S7500 switch to operate in the NTP server
mode. In this case, the remote server operates as the
local time server, and the S7500 switch operates as the
client.
Configure the S7500 switch to operate in NTP peer mode.
In this case, the remote server operates as the peer of the
S7500 switch, and the S7500 switch operates as the
active peer.
Configure the S7500 switch to operate in NTP
broadcast server mode. In this case, the S7500 switch
broadcasts NTP packets through the VLAN interface
configured on the switch.
Configure the S7500 switch to operate in NTP
broadcast client mode. In this case, the S7500 switch
receives broadcast NTP packets through the VLAN
interface configured on the switch.
Configure the S7500 switch to operate in NTP
multicast server mode. In this case, the S7500 switch
sends multicast NTP packets through the VLAN
interface configured on the switch.
Configure the S7500 switch to operate in NTP
multicast client mode. In this case, the S7500 switch
receives multicast NTP packets through the VLAN
interface configured on the switch.
