ntp-service multicast-server
Use ntp-service multicast-server to configure the device to operate in NTP multicast server mode
and use the current interface to send NTP multicast packets.
Use undo ntp-service multicast-server to remove the configuration.
Syntax
ntp-service multicast-server [ ip-address ] [ authentication-keyid keyid | ttl ttl-number | version
number ] *
undo ntp-service multicast-server [ ip-address ]
Default
The device does not operate in any NTP association mode.

Parameters
ip-address: Specifies a multicast IP address. The default is 224.0.1.1. A multicast server and client
must be configured with the same multicast IP address.
authentication-keyid keyid: Specifies the key ID to be used for sending multicast messages to
multicast clients. The value range for the keyid argument is 1 to 4294967295. If you do not specify
this option, the local device cannot synchronize multicast clients enabled with NTP authentication.
ttl ttl-number: Specifies the TTL of NTP multicast messages. The value range for the ttl-number
argument is 1 to 255. The default value is 16.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4. The
default value is 4.
Usage guidelines
After you configure the command, the device periodically sends NTP messages to the specified
multicast address.
If you have configured the device to operate in multicast server mode on an interface with the
command, do not add the interface to any aggregate group. To add the interface to an aggregate
group, remove the configuration of the command.
Examples
# Configure the device to operate in multicast server mode and send NTP multicast messages on
GigabitEthernet 1/0/1 to the multicast address 224.0.1.1, using key 4 for encryption. Set the NTP
version to 4.
