CHAPTER32 HA Configuration
Mediant 4000 SBC | User's Manual
➢ To quickly set up two devices for HA:
1. Make sure that the License Key installed on both devices includes the HA license (see Viewing
the License Key on page672).
2. Obtain the MAC address of each device. The MAC address is displayed on the Device
Information page (see Viewing Device Information on page727).
3. Prepare a single ini file with the following configuration:
● Parameters relating to the first device ("local"):
◆ HALocalMAC - specifies the MAC address
◆ (Optional) HAUnitIdName - defines a descriptive name
◆ (Optional) HARevertiveEnabled - enables the HA Preempt feature
◆ (Optional) HAPriority - defines the priority of the device if the HA Preempt feature is
enabled
● Parameters relating to the second device ("remote"):
◆ HARemoteMAC - specifies the MAC address
◆ HARemoteAddress - defines the HA Maintenance interface address
◆ (Optional) HARemoteUnitIdName - defines a descriptive name
◆ (Optional) HARemotePriority - defines the priority of the device if the HA Preempt
feature is enabled
● InterfaceTable - defines the IP Interfaces table with two network interfaces for the
following Application Types:
◆ OAMP + Media + Control: This is the same for both devices.
◆ HA Maintenance: This is the Maintenance address of the device whose MAC address
is the value of the HALocalMAC parameter.
An example of a configured ini file is shown below:
HALocalMAC = '00908f737a89'
HAUnitIdName = 'Device_1'
HARevertiveEnabled = 1
HAPriority = 6
HARemoteMAC = '00908f594667'
HARemoteAddress = 1.1.1.2
HARemoteUnitIdName = 'Device_2'
HARemotePriority = 4

4. Load the file to both devices (see Loading an ini File to the Device on page76).
5. To test your HA system, perform an HA switchover (see Initiating an HA Switchover on
page648).
