Known issues in SD-WAN 3.2.
The following list includes all known issues that impact an SD-WAN 3.2 release. This list includes both outstanding issues and issues that are addressed, as well as known issues that apply more generally or that are not identified by a specific issue ID. Refer to PAN-OS Release Notes for additional known issues affecting SD-WAN Plugin 3.2.

PAN-236767

Description of PAN-236767.
The web interface won't throw any warning or error if it encounters a failure in importing a certificate. Check the syslog and configd log files for more information.
Ensure the following before importing a certificate:
  • Certificate must be .PKCS12 format.
  • When you bulk import the certificates, the size of the archive(.tar) file should be less than 10MB.

PAN-220919

Description of PAN-220919.
Auto VPN creates a virtual SD-WAN interface named sdwan.901 for direct internet access (DIA) and creates a virtual SD-WAN interface named sdwan.9xx for VPN tunnels. When you enable Auto VPN, the SD-WAN plugin creates the SD-WAN interfaces automatically. Hence, it's not necessary for you to create SD-WAN interfaces manually. The SaaS quality profile works only with one DIA interface that is sdwan.901.
Auto VPN also creates its own default route that uses the sdwan.901 interface as its egress interface and uses a low metric of 5, so that the sdwan.901 interface is preferred over the default route you created.
There might be scenarios where you want to create an SD-WAN interface manually (other than what the SD-WAN plugin creates automatically) like the following:
  • Configuring SD-WAN direct internet access (DIA) links only and no VPN connections between the hub and branch locations
  • (Not recommended) Deploying SD-WAN manually between SD-WAN sites without Panorama management server
In such cases, you must configure the manually created SD-WAN interface outside of the SDWAN.9xx range containing a route with a metric higher than the default value.

PAN-215897

Description of PAN-215897.
In a Panorama high availability (HA) deployment, the SD-WAN interface goes down and all the tunnel interfaces disappear from the
Network
IPSec Tunnels
tab when you push the configuration changes from the secondary Panorama.
Workaround
: If you have set up a HA pair in Panorama, don't push the configuration from the secondary Panorama when the primary Panorama is active. Always push the configuration changes from the primary Panorama when it's active.

PLUG-11223

Description of PLUG-11223.
In a high availability (HA) deployment, the SD-WAN tunnel will go down due to a key ID mismatch when the following events occur in sequence:
  • An HA failover
  • The SD-WAN plugin cache removes the current HA pair relation from the database when
    debug plugins sd_wan drop-config-cache all
    command is executed
  • A commit and push fails on either the hub or a branch active node
In certain scenarios, replacing one of the HA devices during the RMA process can cause the SD-WAN tunnel to go down due to a key ID mismatch. For more details, refer to Replace an SD-WAN Device.
Workaround
: Resolve the Key ID mismatch by ensuring that the
Peer Identification
of the hub firewall matches with the
Local Identification
of the branch firewall and the
Local Identification
of the hub firewall matches with the
Peer Identification
of the branch firewall.
  1. Log in to the hub or a branch firewall where the SD-WAN tunnel is down due to Key ID mismatch and select
    Network
    Network Profiles
    IKE Gateways
    .
  2. Select the IKE gateway of the hub firewall and click
    Override
    at the bottom of the screen.
  3. Copy the
    Local Identification
    value from the hub firewall to the
    Peer Identification
    value in the branch firewall.
  4. Copy the
    Peer Identification
    value from the hub firewall to the
    Local Identification
    value in the branch firewall.
  5. Click
    OK
    and
    Commit
    your changes.
