NTP version number number ranges from 1 to 3 and defaults to 3; the authentication
key ID keyid ranges from 0 to 4294967295; interface-name or interface-type
interface-number specifies the IP address of an interface, from which the source IP
address of the NTP packets sent from the local Ethernet Switch to the peer will be taken;
priority indicates the peer will be the first choice for time server.
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.

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
