Set/Change NTP source

It the external reference NTP server (for time-of-day) is off-line, we can set the Call Server to reference the Primary security server. To do this you have to log in with the admin2 password to the primary and secondary security server and manually change the date and time settings.

Signaling Server(s):

1. Browse to the Primary Signaling Server ELAN local login, eg: https://10.10.10.15/local-login
2. Log in with the admin2 password
3. Click on Local Administration
4. Click on Date and Time
5. Under Network Time Protocol, select Edit
6. Change the Clock Source NTP server type to Primary server
7. Make sure the Type of clock source is Internal
8. Click Save
9. Click Edit under Current System Date and Time
10. Enter the correct date and time for this site
11. Click Save. If the system logs you out, close the browser and log back in with the admin2 password
12. Click on Local Administration
13. Click on Date and Time, and ensure that the correct time is now shown
14. Browse to the Secondary Signaling Server ELAN local login, eg: https://10.10.10.16/local-login
15. Log with the admin2 password
16. Click on Local Administration
17. Select Date and Time
18. Change the Clock Source to Secondary
19. Set the Primary NTP server IP address to the Primary Signaling Server ELAN address (eg, .15)
20. Set the Clock Type to Internal
21. Click Save
22. Under Network Time Protocol, select Sync Now. The time under Current System Date and Time should change. If not, wait about 10 seconds then select Sync Now again under Network Time Protocol

Call Server:

23. Log in to the Call Server, and go to LD 117

    => stat ntp to determine what IP address the Call Server is receiving its NTP time from:

=> stat ntp                                   ⇐ show NTP status

CURRENT NTP CONFIGURATION
NTP Status: ENABLED
Primary IP address: 10.10.10.15               ⇐ NTP server address
Secondary IP address: 0.0.0.0

24. If the Call Server is receiving its NTP time from the Primary Signaling server, manually synchronise the time. If the Call Server is receiving its NTP from another address, go to step 25

    => sync ntp manual
=> sync ntp background

25. If Call Server is receiving its NTP from another address, type:

    => stop ntp background
=> dis ntp
=> chg ntp ipaddr <Primary Signaling Server ELAN>
=> enl ntp
=> sync ntp manual
=> sync ntp background

Example:

=> sync ntp manual                            ⇐ check the server responds
Trying 10.10.10.15......Please do not abort from overlay till sync operation is executed
NTP is not running in secured mode
" ERR0061": Delta between server clock and system clock exceeds the critical threshold level.

NTP Server Time is 10:28:21 on 16-4-2016
Do you want to update the time (y/n)? [n]y    ⇐ yes, I do!

Updated Call Server Time to 10:28:42 on 16-4-2016
