Command History
Usage Guidelines
You can use the
ntp multicast
command to configure an NTP IPv4 or IPv6 multicast server on an
interface. The device then sends multicast packets through that interface periodically.
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 FF02:1::FF0E:8C6C
ip4-address
(Optional) Multicast IPv4 address.
ipv6-address
(Optional) Multicast IPv6 address.
key
key-id
(Optional) Configures the broadcast authentication key number. The range
is from 1 to 65535.
ttl
value
(Optional) Configures the time-to-live (TTL) value of the multicast packets.
The range is from 1 to 255
version
number
(Optional) Configures the NTP version. The range is from 2 to 4.
