    Known Issues in SD-WAN Plugin 2.2

    List of known issues in SD-WAN 2.2 release.
    The following list includes all known issues that impact an SD-WAN 2.2 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 2.2.

    PAN-221755

    Description of PAN-221755.
    In a Panorama high availability (HA) deployment, when you add a new VPN cluster or modify an existing VPN cluster name, the SD-WAN plugin database goes out of sync between the active and passive Panorama.
    Workaround: Run commit force from CLI on the active Panorama after an HA configuration sync on the passive Panorama from the active Panorama.

    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 NetworkIPSec 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.

    PAN-190173

    Pre-shared keys are not synchronized across the Panorama management servers in a high availability (HA) configuration, leading to tunnel flaps during an HA failover when you Push to Devices (CommitPush to Devices or CommitCommit and Push).
    This issue is addressed in SD-WAN plugin 2.2.3 and 3.1.0-h6.

    PLUG-18422

    Description of PLUG-18422.
    If your high availability (HA) firewalls enter an inconsistent HA state, the Panorama management server considers the state of those HA firewalls as active/active, suspended/suspended, or passive-passive. In this case, commits on the Panorama management server will succeed regardless of the state of the firewall. However, Panorama will still display a warning message for an invalid HA pair and will not generate a new configuration for those HA firewalls that are in an inconsistent state. Any new SD-WAN configuration changes to the VPN cluster will not be applied to the inconsistent HA firewalls.
    Workaround: Recover the HA pair in correct state (active/passive). Verify that the inconsistent HA firewalls return to an active/passive HA state by running the XML API show devices all command. After the verification, you can again commit your changes on the Panorama management server to push the changes to all firewalls.

    PLUG-17728

    Description of PLUG-17728.
    While upgrading from SD-WAN plugin 2.2.6 version to 2.2.7, you may encounter the following commit error:
    IP address from vpn address pool subnet/subnets are exhausted.
    Workaround: Add a new VPN address pool.

    PLUG-17704

    Description of PLUG-17704.
    The SD-WAN plugin enforces all the HA firewalls in the SD-WAN cluster to be in a complete functional state. Due to this enforcement, even when one firewall goes nonfunctional, the SD-WAN plugin prevents making configuration changes to any of the HA firewalls in the SD-WAN cluster.
    This issue is addressed in SD-WAN plugin 2.2.7.

    PLUG-16507

    Description of PLUG-16507.
    (HA deployments only) You may observe SD-WAN tunnel flapping and changes to the SD-WAN interfaces when you perform a commit operation after any of the following:
    • HA failover
    • PAN-OS upgrade or downgrade
    • Reboot the HA pair
    This issue is addressed in SD-WAN plugin 3.3.2, 3.3.1 , 3.2.2, 3.0.8 , and 2.2.7.

    PLUG-16141

    Description of PLUG-16141.
    The SD-WAN log files are overwritten and the critical events does not get captured in the system logs that cause difficulty in debugging the SD-WAN plugin-related issues.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.8 , 3.2.2, and 3.3.2. After the fix, the following critical events are added to the system logs.
    • PSK creation or PSK change for a VPN cluster
    • Tunnel name, IP address creation, or IP address change

    (Full mesh topology only) The SD-WAN devices neither go out-of-sync nor show up in the commit scope when a new hub device gets added to the full mesh VPN cluster.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.7-h2, 3.0.8, 3.2.2, 3.3.1, and 3.3.2.

    PLUG-15761

    Description of PLUG-15761.
    In some cases, after HA failover followed by a commit and commit push from the Panorama will result in the tunnel going down. It's because a new tunnel IP address gets generated for the firewall after a HA failover.
    Workaround: After committing the configuration changes to Panorama, perform a commit and push on the all the SD-WAN devices in the SD-WAN VPN cluster even if the templates are in synchronization with the Panorama management server.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.8, 3.2.2, 3.3.1, and 3.3.2.

    PLUG-15525

    Description of PLUG-15525.
    It's not possible to revert to any of the earlier pre-shared keys except the current pre-shared key.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.8 , 3.2.2, and 3.3.2. After the fix, you can revert to any of the earlier pre-shared keys (if it's available).

    PLUG-15415

    Description of PLUG-15415.
    (HA deployments only) The HA synchronization failure occurs on the passive Panorama when you either upgrade or downgrade the HA Panorama. The issue is caused due to HA failover between the active and passive SD-WAN devices.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.8, , 3.2.2, 3.3.1, and 3.3.2.

    PLUG-14413

    Description of PLUG-14413.
    (HA Deployments only) If the HA environment is not configured correctly or when either of HA pair is not present, then no proper commit failure is displayed for troubleshooting.
    This issue is addressed in SD-WAN plugin 2.2.7, 3.0.8, 3.2.2, and 3.3.2. After the fix, the improved failure message helps in identifying the missing HA device in the HA deployment.

    PLUG-14402

    Description of PLUG-14402
    The return merchandise authentication (RMA) process won't be successful if you delete the replacement firewall without removing it from the SD-WAN plugin first.
    This issue is addressed in SD-WAN plugin 2.2.6, 3.0.7, 3.2.1, and 3.3.0. Follow the instructions to replace an SD-WAN device.

    While configuring SD-WAN Interface Profile (NetworkNetwork ProfilesSD-WAN Interface Profile) on the branch device, disabling VPN Data Tunnel Support for MPLS Link Type will throw a commit failure on the firewall.
    This issue is addressed in SD-WAN plugin 2.2.5. After the fix, the commit failure is not thrown on the firewall.

    PLUG-13152

    Description of PLUG-13152
    The SD-WAN plugin creates predefined zones automatically that does not require any user configuration. Hence, we have removed the following predefined zones tabs from the SD-WAN plugin web interface:
    • Zone Internet
    • Zone to Hub
    • Zone to Branch
    • Zone Internal
    This issue is addressed in SD-WAN plugin 2.2.5 and 3.0.5.

    PLUG-12724

    Description of PLUG-12724.
    Configuration synchronization between Panorama HA peers fails after downgrading from the following SD-WAN plugin releases.

    PLUG-12224

    Description of PLUG-12224.
    For an SD-WAN tunnel between a hub and a branch, the hub/branch tunnel interface should have the same IP address on the HA active and passive firewalls, but the hub/branch has different IP addresses on the HA active and passive firewalls.
    This issue is addressed in SD-WAN plugin 2.2.4, 2.2.7, 3.0.4, 3.0.8, 3.1.0-h6 , 3.2.2, and 3.3.2. Tunnel ID changes will take effect from SD-WAN plugin 2.2.4. If you are running SD-WAN plugin 2.2.2 and upgrade to 2.2.4, you must regenerate the cluster configuration and push to devices to see those changes.

    PLUG-12156

    Description of PLUG-12156
    On the Hub-Spoke VPN cluster type, if you make any changes to an existing cluster member configuration or add a new device to the cluster, the push gets enabled for all the VPN cluster members.
    This issue is addressed in SD-WAN plugin 2.2.6 , 3.0.7-h2, 3.2.1 , and 3.3.0.

    PLUG-12126

    Description of PLUG-12126
    The VPN cluster is recreated when the name of an existing VPN cluster is modified. As a result, the pre-shared key and tunnel IP addresses changes causing failure to establish the VPN tunnel (or tunnel flaps).
    This issue is addressed in SD-WAN plugin 2.2.6, 3.0.7, and 3.1.3. After this fix, you won't be able to modify the existing VPN cluster name.

    PLUG-11789

    Pre-shared keys are not synchronized across the Panorama management servers in a high availability (HA) configuration, leading to tunnel flaps during an HA failover when you Push to Devices (Commit > Push to Devices or Commit > Commit and Push).
    This issue is addressed in SD-WAN plugin 2.2.3, 3.0.4, and 3.1.0-h6.

    PLUG-11761

    Description of PLUG-11761.
    Prisma Access onboarding is unsuccessful using SD-WAN plugin 2.2.2 and after filling out all the required information, the plugin shows the PHP bit error. Users are unable to onboard Prisma Access on a branch firewall.
    This issue is addressed in SD-WAN plugin 2.2.3, 3.0.4, and 3.1.0-h6.

    PLUG-11453

    Description of PLUG-11453.

    PLUG-11383

    Description of PLUG-11383.
    SD-WAN plugin fails to get Prisma Access connection details for the onboarding process.
    This issue is addressed in SD-WAN plugin 2.2.3 and 3.0.4.

    PLUG-11277

    Description of PLUG-11277
    In an SD-WAN hub-and-spoke topology, where Prisma Access compute nodes (CNs) are configured as a hub connecting to the PAN-OS firewalls, the session gets established on only one compute node when ECMP is disabled. When more than one compute nodes are connected to the PAN-OS firewalls, routes get added from one of the compute nodes only. Even though the branch firewalls learn the routes through BGP from both the Prisma Access compute nodes, the branch installs only one of the BGP routes based on the BGP route selection criteria. Therefore, when a traffic passes from the other compute node, the session does not get established.
    This issue is addressed in SD-WAN plugin 2.2.6, 3.0.7, 3.1.3, and 3.2.1.

    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 NetworkNetwork ProfilesIKE 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.
    This issue is addressed in SD-WAN plugin 2.2.5 , 2.2.7, 3.0.8, 3.1.3 , 3.2.1, 3.2.2 , 3.3.0, and 3.3.2.
    After this fix, the key ID may change after the Panorama commit. Therefore, you must ensure to commit and push to all the devices in the VPN cluster or clusters.

    PLUG-11062

    Description of PLUG-11062.
    When configuring upstream NAT on the SD-WAN plugin, the drop-down does not list AE interface or subinterface, even though the firewall is configured with AE interface or subinterface.
    This issue is addressed in SD-WAN plugin 2.2.3 and 3.0.4.

    PLUG-10796

    On the Panorama management server, a commit (CommitCommit to Panorama) hangs at 99% and causes the commit queue to fill up, preventing any subsequent commits on Panorama.
    This issue is addressed in SD-WAN plugin 2.2.2 and 3.0.2.

    PLUG-10457

    After successful upgrade to SD-WAN 2.1.0 and later releases, the Panorama management server takes 10 minutes to commit (CommitCommit to Panorama) configuration changes regardless of what configuration change was made.
    This issue is addressed in SD-WAN plugin 2.2.2 and 3.0.2.

    PLUG-10432

    The SD-WAN plugin is unable to retrieve the Prisma Service IP, preventing the onboard of Prisma Access tenants.
    This is addressed in SD-WAN plugin 2.2.2 and 3.0.2.

    PLUG-10165

    On the Panorama management server, commits (CommitCommit to Panorama) fail if your SD-WAN firewalls associated with the SD-WAN plugin (PanoramaSD-WAN) configuration are removed from Panorama management (PanoramaManaged DevicesSummary).
    Workaround: Remove the SD-WAN configuration after you remove your SD-WAN firewalls from Panorama management.
    1. Log in to the Panorama web interface.
    2. Select PanoramaPlugins and search for sd_wan.
    3. Remove Config.
    4. Click OK to confirm removing the SD-WAN configuration from Panorama.
