Changing the management IP address of EMS requires a change in the NTP IP address configuration on the Avaya SBC devices connected to EMS. For proper functioning of OpenVPN, ensure that the date and time on the Avaya SBC devices match those on the EMS device. Avaya recommends configuring the EMS IP address as the NTP IP address of the Avaya SBC devices.
Before you begin
If you plan to use the system password while running the command, ensure to have it ready.
Procedure
Log in to the Avaya SBC device as a super user.
Enter the following command:
sbceconfigurator.py change-ntp-ipNewNTPIPAddress<yes/no> <if yes provide PASSWORD>
Where:
NewNTPIPAddress is the new NTP IP address.
<yes/no> <if yes provide PASSWORD> is either yes or no. If you type yes, you must enter the system password after running the command.
