Ntp Configuration Task List - H3C S3100-52P Operation Manual

Operation Manual – NTP
H3C S3100-52P Ethernet Switch
NTP implementation
Broadcast mode
Multicast mode
Caution:
When an H3C S3100-52P Ethernet switch works in server mode or symmetric
passive mode, you need not to perform related configurations on this switch but do
that on the client or the symmetric-active peer.
The NTP server mode, NTP broadcast mode, or NTP multicast mode takes effect
only after the local clock of the H3C S3100-52P Ethernet switch has been
synchronized.
When symmetric peer mode is configured on two Ethernet switches, to synchronize
the clock of the two switches, make sure at least one switch's clock has been
synchronized.

1.2 NTP Configuration Task List

Complete the following tasks to configure NTP:
Configuring NTP Implementation Modes
Configuring Access Control Right
Configuring NTP Authentication
Configuring Optional NTP Parameters
Displaying NTP Configuration
mode
Configure the local S3100-52P Ethernet switch to work
in NTP broadcast server mode. In this mode, the local
switch broadcasts NTP messages through the VLAN
interface configured on the switch.
Configure the S3100-52P switch to work in NTP
broadcast client mode. In this mode, the local
S3100-52P switch receives broadcast NTP messages
through the VLAN interface configured on the switch.
Configure the local S3100-52P Ethernet switch to work
in NTP multicast server mode. In this mode, the local
switch sends multicast NTP messages through the
VLAN interface configured on the switch.
Configure the local S3100-52P Ethernet switch to work
in NTP multicast client mode. In this mode, the local
switch receives multicast NTP messages through the
VLAN interface configured on the switch.
