III. Configure NTP Broadcast Server Mode
Designate an interface on the local Ethernet Switch to transmit NTP broadcast packets.
In this case, the local equipment operates in broadcast mode and serves as a
broadcast server to broadcast messages to its clients regularly.
Perform the following configurations in VLAN interface view.

NTP version number number ranges from 1 to 3 and defaults to 3; the authentication
key ID keyid ranges from 0 to 4294967295; This command can only be configured on
the interface where the NTP broadcast packets will be transmitted.
IV. Configure NTP Broadcast Client Mode
Designate an interface on the local Ethernet Switch to receive NTP broadcast
messages and operate in broadcast client mode. The local Ethernet Switch listens to
the broadcast from the server. When it receives the first broadcast packets, it starts a
brief client/server mode to switch messages with a remote server for estimating the
network delay. Thereafter, the local Ethernet Switch enters broadcast client mode and
continues listening to the broadcast and synchronizes the local clock according to the
arrived broadcast message.
Perform the following configurations in VLAN interface view.
Table 7-4 Configure NTP broadcast client mode
Configure NTP broadcast client mode
Disable NTP broadcast client mode
This command can only be configured on the interface where the NTP broadcast
packets will be received.
V. Configure NTP Multicast Server Mode
Designate an interface on the local Ethernet Switch to transmit NTP multicast packets.
In this case, the local equipment operates in multicast mode and serves as a multicast
server to multicast messages to its clients regularly.
