ip-address: Multicast IP address, which defaults to 224.0.1.1.
authentication-keyid keyid: Specifies the key ID to be used for sending multicast messages to multicast
clients, where keyid is in the range of 1 to 4294967295. This parameter is not meaningful if
authentication is not required.
ttl ttl-number: Specifies the TTL of NTP multicast messages, where ttl-number is in the range of 1 to 255
and defaults to 16.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and the
default is 3.
Examples
# Configure the device to operate in multicast server mode and send NTP multicast messages on
GigabitEthernet 0/1 to the multicast address 224.0.1.1, using key 4 for encryption, and set the NTP

Parameters
ip-address: IP address of the local clock, which is 127.127.1.u, where u is the NTP process ID in the range
of 0 to 3. If you do not specify ip-address, i t d e f a u l t s t o 127.127.1.0 .
stratum: Stratum level of the local clock, in the range of 1 to 15. The default is 8. The stratum level of a
clock defines the clock precision. A lower stratum level represents a higher clock accuracy.
Examples
# Specify the local clock as the reference source, with the stratum level 3.
