AudioCodes Mediant 800 - Quick-And-Easy Initial HA Configuration

CHAPTER41 HA Configuration
Mediant 800 Gateway & E-SBC | User's Manual
When synchronization completes, the redundant device resets to apply the received
configuration and software.
When both devices become operational in HA, the HA status is indicated as follows:
● Both devices: The Web interface's Monitor page displays "Operational" in the 'HA Status'
field.
● Active device: The Status LED is lit green - slow-flash, steady on, and then slow flash.
● Redundant device: The Status LED is lit green - slow-fast flash.
3. Access the active device with its' OAMP IP address and configure the device as required. For
information on configuration done after HA is operational, see Configuration while HA is
Operational.
Quick-and-Easy Initial HA Configuration
You can quickly set up two stand-alone devices into an HA system, by loading the same ini
configuration file with special parameters to each device. This ini file contains basic configuration
that identifies the devices by MAC address and applies the configuration accordingly.
➢ 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927).
2. Obtain the MAC address of each device. The MAC address is displayed on the Device
Information page (see Viewing Device Information on page983).
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'
