After value being given, device will again prompt asking for any other parameter to be changed in NTP
settings configuration menu
. If there are no parameters to be modified, then enter “0” in “Enter
command:” prompt. Thereafter it will ask to save modified parameters. Enter “y” or “Y” for yes and “n” or
“N” for not saving them. Once saved, check the parameters update by using option “1” in general settings
NTP main menu. Refer above figure.
For detailed understanding of each NTP parameter functioning, refer NTP operation section 11.3.
FUNCTIONALITY
It is necessary to restart NTP service using option “7” in NTP main menu in
order for new changes to take effect. Refer section 11.3 for complete
understanding of NTP operation.
To configure NTP Symmetric Key based Authentication
NTP Authentication between server and client can be provided using Symmetric key based authentication
or Autokey based authentication using PC and IFF scheme. Detailed explanation of NTP authentication is
provided in section 11.3.3.4.
MTS200 provides only NTP symmetric key based authentication configuration using SSH, Telnet, serial
console port and webserver. However, NTP Autokey based authentication configuration is only provided
using webserver access.
In order to configure NTP for symmetric key based authentication, it is necessary to configure key Id
number and key string (which will be the key identification password) for authentication in ntp.keys file
