Configuring HA
The first task in setting up HA after initial setup is configuring
the
High Availability > Settings page on the Primary ADTRAN
security appliance. Once you configure HA on the Primary
ADTRAN security appliance, it communicates the settings to
the Backup ADTRAN security appliance.
To configure HA on the Primary appliance, perform the
following steps:
7. Navigate to the High Availability > Settings page. Select
the Enable High Availability checkbox.
8. Under ADTRAN Address Settings , type in the serial
number for the Backup ADTRAN appliance.
You can find the serial number on the back of the ADTRAN
security appliance, or in the
System > Status screen of the
backup unit. The serial number for the Primary ADTRAN
appliance is automatically populated.
9. Click Apply to retain these settings.
Configuring Advanced High Availability Settings
10. Navigate to the High Availability > Advanced page. To
configure Stateful HA, select Enable Stateful
Synchronization . A dialog box is displayed with
recommended settings for the Heartbeat Interval and
Probe Interval fields. The settings it shows are minimum
recommended values. Lower values may cause
unnecessary failovers, especially when the appliance is
under a heavy load. You can use higher values if your
appliance handles a lot of network traffic. Click
OK .
Tip:
Preempt mode is recommended to be disabled after
enabling Stateful Synchronization. This is because
preempt mode can be over-aggressive about failing
over to the backup appliance.
11. To backup the firmware and settings when you upgrade the
firmware version, select Generate/Overwrite Backup
Firmware and Settings When Upgrading Firmware .
12. Select the Enable Virtual MAC checkbox. Virtual MAC
allows the Primary and Backup appliances to share a
single MAC address. This greatly simplifies the process of
updating network ARP tables and caches when a failover
occurs. Only the WAN switch to which the two appliances
are connected to needs to be notified. All outside devices
will continue to route to the single shared MAC address.
