Usage Guidelines
You can use the
ntp multicast client
command to configure an NTP multicast client on an interface. The
device then listens to NTP multicast messages and discards any messages that come from an interface
for which multicast is not configured.
Use NTP broadcast or multicast associations when time accuracy and reliability requirements are
modest, your network is localized, and the network has more than 20 clients. We recommend that you
use NTP broadcast or multicast associations in networks that have limited bandwidth, system memory,
or CPU resources.
This command does not require a license.
Examples
This example shows how to configure an NTP IPv6 multicast server on an interface:
switch(config)#
interface ethernet 6/1
switch(config-if)#
ntp multicast client FF02:1::FF0E:8C6C
ip4-address
(Optional) Multicast IPv4 address.
ipv6-address
(Optional) Multicast IPv6 address.
