1.2.1 Prerequisites
When an S3900 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 S3900 switch
operates in NTP broadcast mode or NTP multicast mode, you need to perform
configurations on both the server side and the client side.
Configuration on S3900 switches
Configure the S3900 switch to operate in
NTP broadcast server mode. In this case,
the S3900 switch broadcast NTP packets
through the VLAN interface configured on
the switch.
Configure the S3900 switch to operate in
NTP broadcast client mode. In this case,
the S3900 switch receives broadcast NTP
packets
configured on the switch.
Configure the S3900 to operate in NTP
multicast server mode. In this case, the
S3900 switch sends multicast NTP packets
through the VLAN interface configure on
the switch.
Configure the S3900 switch to operate in
NTP multicast client mode. In this case, the
S3900 switch receives multicast NTP
packets
configure on the switch.
