Configure HA Devices for SD-WAN
Configure Active/Passive HA for two SD-WAN branches or hubs.
You can configure two firewalls as a branch in active/passive HA mode (or two firewalls as a hub
in active/passive HA mode) to be part of your SD-WAN environment. In this case,
Panorama™ needs to push the same configuration to the active peer and the passive
peer, rather than treat the two firewalls individually. To make that happen, you
configure active/passive HA before adding the devices for SD-WAN, so that Panorama
is aware the devices are HA peers and pushes the same configuration to them. (Only
HA active/passive mode is supported.)
Read
through the following procedure before you begin so you don’t Commit
after adding your HA peers as SD-WAN devices.
In
HA, the firewall does not synchronize SD-WAN session distribution
statistics. After an HA failover, the session distribution statistics
display only statistics of new sessions; statistics of existing
sessions are lost.
- Before you enable SD-WAN on your HA peers, configure Active/Passive HA on two firewall models that support SD-WAN.Add the HA peers as SD-WAN devices, but don’t perform the last step to Commit.In Panorama, select .At the bottom of the screen, select Group HA Peers. Confirm that under the Status display, the HA Status column includes the two firewalls, one Active and one Passive. Panorama is aware of the HA status and will push the same SD-WAN configuration to the two HA peers when you commit.Commit and Commit and Push.
Convert Standalone Panorama to Panorama HA/Replace a HA Peer
(SD-WAN plugin 2.2.7 and later 2.2 versions) If you have configured SD-WAN on a standalone Panorama management server and want to convert it as one of the Panorama HA peers, you can do so by following the below steps. You can perform this conversion while retaining the existing SD-WAN configuration. The converted standalone Panorama can act as an active or a passive HA peer.- On the new Panorama management server, configure the management IP address, configure HA, and install the appropriate licenses.If you have configured the converted Standalone Panorama as an active Panorama HA peer, then you must configure the new Panorama as a passive HA peer.(On Active HA peer only) (Mandatory) After configuring the active and passive Panorama, you must synchronize the mongoDB SD-WAN collections by executing the debug plugins sd_wan mongo-db sync-db-to-peer command manually.
