which the source IP address of the NTP packets sent from the local Switch to the
peer will be taken;
priority indicates the peer will be the first choice for the time
server.
Configuring NTP Broadcast Server Mode
Designate an interface on the local 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 the VLAN interface view.

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.
Configuring NTP Broadcast Client Mode
Designate an interface on the local Switch to receive NTP broadcast messages and
operate in broadcast client mode. The local 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 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 the VLAN Interface View.
Table 439 Configure NTP Broadcast Client Mode
This command can only be configured on the interface where the NTP broadcast
packets will be received.
Configuring NTP Multicast Server Mode
Designate an interface on the local 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.
Perform the following configurations in the VLAN Interface View.
