Configuring Ntp Broadcast Mode; Configuring Ntp Multicast Mode - HP MSR Series Configuration Manual

Step
2. Specify a symmetric-passive
peer for the device.

Configuring NTP broadcast mode

The broadcast server periodically sends NTP broadcast messages to the broadcast address
255.255.255.255. After receiving the messages, the device operating in NTP broadcast client mode
sends a reply and synchronizes its local clock.
Configure the NTP broadcast mode on both the server and clients. The NTP broadcast mode can only be
configured in a specific interface view because an interface needs to be specified on the broadcast
server for sending NTP broadcast messages and on each broadcast client for receiving broadcast
messages.
For more information about tunnel interfaces, see Layer 3—IP Services Configuration Guide.
Configuring a broadcast client

3. Configure the device to
operate in NTP broadcast
server mode.

Configuring NTP multicast mode

The multicast server periodically sends NTP multicast messages to multicast clients, which send replies
after receiving the messages and synchronize their local clocks.

Remarks
By default, no symmetric-passive
peer is specified.
The ip-address argument must be a
unicast address, rather than a
broadcast address, a multicast
address, or the IP address of the
local clock.
Remarks

This command enters the view of
the interface for sending NTP
broadcast messages.

A broadcast server can
synchronize broadcast clients only
when its clock has been
synchronized.
