* Warning * The clustering issues listed as Resolved below (#43309, #44354, #44792) required protocol changes to the information exchanged between the VMware SD-WAN Gateway and VMware SD-WAN Edge.  Though no issues were found during interoperability testing (and not all customers may experience issues), it has come to our attention that these protocol changes may cause a Spoke Edge to connect to more than one Hub in a cluster, which could potentially impact return routing of traffic.

As a result, Spoke Edges which connect to Hub Clusters must wait for Gateways to be upgraded to 3.4.2 prior to being upgraded themselves.


Warning: VMware SD-WAN Release 2.x (e.g. 2.4.4, 2.5.2, etc.) is no longer supported.

For more information regarding Release 2.x, including next steps, please consult the following KB article:

Announcement: End of Support Life for VMware SD-WAN Release 2.x.x (77221)


Important Notes

Change in the Edge 520/540 switch port MAC address

On a VMware SD-WAN Edge using release 3.3.x or lower, the internal port naming (as seen when querying SNMP) was a logical name such as "sw1p0". In Release 3.4.0+, this was improved to assign proper logical names (e.g. lan1") so that users can easily map them to the actual connected ports. 

In addition, when an Edge 520 or 540 is upgraded to 3.4.0 or higher, not only does the port naming change, the switchports sw1p0 - sw1p3 will have their MAC address changed as well.  For an Edge 520/540, the switchports sw1p0 -sw1p3 correspond to LAN ports LAN1-LAN4.
Any downstream device which filters for a specific source MAC exiting from an Edge 520/540’s LAN1-LAN4 interfaces must be made aware of this MAC address change. The new MAC address upon upgrade to 3.4.0 or higher will only differ in the final  character of the address. The eth1 MAC change to eth0 MAC will be the current MAC address with the final character one lower value.  For example, if the MAC address ends in 1, the new MAC will end in 0.  If the MAC ends in B, the new MAC will end in A.

Feature Enhancements

Upgrade Banners

Operator users can post an Upgrade Banner on the VMware SD-WAN Orchestrator when an upgrade is scheduled to notify users of the scheduled upgrade.  Previously, when the banner was posted, all users who logged into the Orchestrator would see the banner.

In Release 3.4.2, the display of this banner may be configured so that only certain groups will see the banner.  Specifically, the banner can be configured to be visible for the following user groups: 

  1. Operator only
  2. Operator and Partner only
  3. Operator, Partner, and Customer

System Information

For a VMware SD-WAN Edge using Release 3.4.2, the Remote Diagnostic “System Health” is renamed “System Information”.  In addition to displaying Edge system load and recent WAN link stability statistics as before, “System Information” adds information on the monitoring services NetFlow and Syslog.  

The new Monitoring Services field includes the service type, the destination IP, the source interface, the segment being used, and the interface selection type.

Resolved Issues

The resolved issues are grouped as follows.

Gateway Resolved Issue

Resolved in Gateway Version  R342-20200706-GA-46261-47204

The below issue has been resolved since 3.4.2 Gateway version R342-20200630-GA-46261.

  • Fixed Issue 47204:

    When a VMware SD-WAN Cluster Hub Edge reaches 70% or greater tunnel capacity, the VMware SD-WAN Gateway will re-balance the Spoke Edges. If the total tunnel capacity is greater than 70% of all other Hubs in the Cluster, the Gateway’s re-balancing will not work properly and lead to continuous re-balancing.

Gateway Resolved Issue

Resolved in Gateway Version R342-20200630-GA-46261

The below issue has been resolved since 3.4.2 Gateway version R342-20200610-GA.

  • Fixed Issue 46261:

    A VMware SD-WAN Gateway will leak peer objects over time, which eventually results in a Dataplane Service Failure. The frequency of failures will be dictated by the number of Edges connected to the Gateway, and the volume of path flaps. In the worst case, a Dataplane Service Failure occurs approximately every two weeks for a Gateway with 3000+ Edges and unstable tunnels.

Edge/Gateway Resolved Issues

Resolved in R342-20200610-GA

    For a site using a High Availability topology, the VMware SD-WAN Standby may suffer a Dataplane Service Failure and restart when the Active Edge tries to sync a high number of flows (e.g., ~1.8M UDP flows) with the Standby Edge. The user will also observe a large number of HA_FAILED and HA_READY messages on the Orchestrator.

  • Issue 45302:

    In a VMware SD-WAN Hub Cluster, if one Hub loses connectivity for more than 5 minutes to all of the VMware SD-WAN Gateways common between itself and its assigned Spoke Edges, the Spokes may in rare conditions be unable to retain the hub routes after 5 minutes. The issue resolves itself when the Hub regains contact with the Gateways.

  • Issue 45345:

    When a VMware SD-WAN Edge connected to a Zscaler GRE tunnel sends IP fragmented traffic, ISPs in France have been observed to incorrectly set the IP length in the GRE packet set to the length of the entire reassembled packet instead of the length of the first fragment and as a result the packets are dropped on the GRE tunnel.

  • Issue 45542:

    When a VMware SD-WAN Hub Edge is removed from a Hub Cluster, the Spoke Edges remain associated with that removed Hub Edge and are not reassigned to other Hub Edges in the Cluster.

    Workaround: For the Hub Edge that is removed, run the Remote Diagnostic utility “Redistribute Spokes excluding this Hub” found under the “Rebalance Hub Cluster” section.

  • Issue 45820:

    Port forwarding works for one LAN subnet when the same NAT IP is configured for multiple LAN subnets.

  • Issue 46137:

    A VMware SD-WAN Edge running 3.4.x software does not initiate a tunnel with AES-GCM encryption even if the Edge is configured for GCM.

  • Issue 46320:

    A pair of VMware SD-WAN Edge model 610’s may not be able to form a High Availability pair.

  • Issue 46628:

    The GE5 and GE6 ports on a VMware SD-WAN Edge 620/640/680 do not detect a link if the ports are configured with 100 Mbps and duplex.

  • Issue 47355:

    When the same route is learned via local underlay BGP, Hub BGP and/or statically configured on the Partner Gateway, the sorting order of the routes is incorrect with the Hub BGP being preferred over the underlay BGP.

  • Issue 47681:

    When a host on the LAN side of a VMware SD-WAN Edge uses the same IP as that Edge’s WAN interface, the connection from the LAN host to the WAN does not work.

  • Issue 48175:

    A VMware SD-WAN Edge running Release 3.4.2 will form an OSPF adjacency on a non-global segment if the non-global segment has an interface configured in the same IP range as an interface configured on the global segment

  • Issue 48502:

    In some scenarios, a VMware SD-WAN Hub Edge being used to backhaul internet traffic may experience a Dataplane Service Failure due the improper handling of backhaul return packets.

Orchestrator Known Issues
  • Issue 19566:

    After High Availability failover, the serial number of the standby VMware SD-WAN Edge may be shown as the active serial number in the Orchestrator.

  • Issue 20900:

    If the MaxMind geolocation service is enabled and cannot reach the MaxMind server, new VMware SD-WAN Edge activations will not work.

  • Issue 24269:

    Monitor > Transport > Loss not graphing observed WAN link loss while QoE graphs do reflect this loss. 

  • Issue 32335:

    The ‘End User Service Agreement’ (EUSA) page throws an error when a user is trying to accept the agreement.

    Workaround: Ensure no leading or trailing spaces are found in Enterprise Name.

  • Issue 33026:

    The ‘End User Service Agreement’ (EUSA) page does not reload properly after deleting the agreement.

  • Issue 35658:

    When a VMware SD-WAN Edge is moved from one profile to another which has a different CSS setting (e.g. IPsec in profile1 to GRE in profile2), the Edge level CSS settings will continue to use the previous CSS settings (e.g. IPsec versus GRE). 

    Workaround: Disable and then reenable GRE at the Edge level to resolve the issue.

  • Issue 35667:

    When a VMware SD-WAN Edge is moved from one profile to another profile which has the same CSS setting but a different GRE CSS name (the same endpoints), some GRE tunnels will not show in monitoring.

    Workaround: Disable and then reenable GRE at the Edge level to resolve the issue.

  • Issue 38843:

    When pushing an application map, there is no Operator event, and the Edge event is of limited utility.

  • Issue 39790:

    The VMware SD-WAN Orchestrator allows a user to configure a VMware SD-WAN Edge’s routed interface to have greater than the supported 32 subinterfaces, creating the risk that a user can configure 33 or more subinterfaces on an interface which would cause a Dataplane Service Failure for the Edge.

  • Issue 40341:

    Though the Skype application is properly categorized on the backend as Real Time traffic, when editing the Skype Business Policy on the VMware SD-WAN Orchestrator, the Service Class may erroneously display “Transactional”.

  • Issue 40567:

    A user is able to clone a customer enterprise even though the customer's profile includes partner gateways (which cannot be cloned) and there is no clear error message about why attempting this will not work.

  • Issue 40746:

    Connected subnets and static routes associated with subinterfaces may not show up as expected on the Configure > Overlay Flow Control screen of the VMware SD-WAN Orchestrator.

    Workaround: Ignore the duplicate event.
