Use the undo ntp-service multicast-server command to remove the configuration. 
Examples 
# Configure the device to work in the multicast server mode and send NTP multicast messages on 
VLAN-interface 1 to the multicast address 224.0.1.1, using key 4 for encryption, and set the NTP 
version to 3.

ntp-service refclock-master 
Syntax 
ntp-service refclock-master [ ip-address ] [ stratum ] 
undo ntp-service refclock-master ip-address ] 
View 
System view 
Default Level 
2: System level 
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, it defaults to 127.127.1.0.  
stratum: Stratum level of the local clock, in the range of 1 to 15 and defaulting to 8. 
Description 
Use the ntp-service refclock-master command to configure the local clock as a reference source for 
other devices.  
Use the undo ntp-service refclock-master command to remove the configuration. 
 
 
The stratum level of a clock defines the clock precision. The value range is 1 to 16. The clock precision 
decreases from stratum 1 to stratum 16. A stratum 1 clock has the highest precision, and a stratum 16 
clock is not synchronized and cannot be used as a reference clock.  
 
Examples 
# Specify the local clock as the reference source, with the stratum level of 3.
