7.2.1 Configure NTP Operating Mode

You can set the NTP operating mode of an Ethernet Switch according to its location in
the network and the network structure. For example, you can set a remote server as the
time server of the local equipment. In this case the local Ethernet Switch works as an
NTP client. If you set a remote server as a peer of the local Ethernet Switch, the local
equipment operates in symmetric active mode. If you configure an interface on the local
Ethernet Switch to transmit NTP broadcast packets, the local Ethernet Switch will
operates in broadcast mode. If you configure an interface on the local Ethernet Switch
to receive NTP broadcast packets, the local Ethernet Switch will operates in broadcast
client mode. If you configure an interface on the local Ethernet Switch to transmit NTP
multicast packets, the local Ethernet Switch will operates in multicast mode. Or you
may also configure an interface on the local Ethernet Switch to receive NTP multicast
packets, the local Ethernet Switch will operates in multicast client mode.

Note:
All the NTP operating modes create sessions except the NTP Server Mode after the
relevant configuration.
Only the sessions created by NTP peer mode, NTP broadcast client mode and NTP
multicast client mode are dynamic sessions. Other sessions are static sessions.
I. Configure NTP Server Mode
Set a remote server whose ip address is ip-address as the local time server. ip-address
specifies a host address other than a broadcast, multicast or reference clock IP
address. In this case, the local Ethernet Switch operates in client mode. In this mode,
only the local client synchronizes its clock with the clock of the remote server, while the
reverse synchronization will not happen.
Perform the following configurations in system view.
