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


Warning: VMware SD-WAN Releases 3.2.x and 3.3.x have both reached the End of Support. Releases 3.2.x and 3.3.x reached End of General Support (EOGS) on December 15, 2021, and End of Technical Guidance (EOTG) March 15, 2022.


Warning: VMware SD-WAN Releases 3.4.x is approaching End of Support for the Orchestrator and Gateway. Release 3.4.x for the Orchestrator and Gateway will reach End of General Support (EOGS) on March 30, 2022, and End of Technical Guidance (EOTG) September 30, 2022.
Note: This is for the Orchestrator and Gateway only. 3.4.x software for the Edge is scheduled to enter its End of Support window beginning on December 31, 2022.

For more information on SD-WAN Release 3.x software lifecycles, please consult the Knowledge Base article: Announcement: End of Support Life for VMware SD-WAN Release 3.x (84151)


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.

Limitation When Disabling Autonegotiation on VMware SD-WAN Edge Models 520, 540, 620, 640, 680, 3400, 3800, and 3810

When a user disables autonegotiation to hardcode speed and duplex on ports GE1 - GE4 on a VMware SD-WAN Edge model 620, 640 or 680; on ports GE3 or GE4 on an Edge 3400, 3800, or 3810; or on an Edge 520/540 when an SFP with a copper interface is used on ports SFP1 or SFP2, the user may find that even after a reboot the link does not come up.

This is caused by each of the listed Edge models using the Intel Ethernet Controller i350, which has a limitation that when autonegotiation is not used on both sides of the link, it is not able to dynamically detect the appropriate wires to transmit and receive on (auto-MDIX). If both sides of the connection are transmitting and receiving on the same wires, the link will not be detected. If the peer side also does not support auto-MDIX without autonegotiation, and the link does not come up with a straight cable, then a crossover Ethernet cable will be needed to bring the link up.

For more information please see the KB article Limitation When Disabling Autonegotiation on VMware SD-WAN Edge Models 520, 540, 620, 640, 680, 3400, 3800, and 3810 (87208).

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

  • Fixed Issue 43309:

    On a VMware SD-WAN Cluster, when the Super Gateway restarts, the Spoke Edges are re-balanced.

  • Fixed Issue 43333:

    When a customer with a very high route count adds a Non-VeloCloud site to a VMware SD-WAN Gateway and backhauls internet traffic through it, the route lookup causes high packet latency which impacts NVS throughput.  This issue affects other customers with an NVS using the same Gateway.

  • Fixed Issue 43344:

    When a custom VLAN is configured on a user defined overlay, the next hop ARP fails, and a tunnel does not form.

  • Fixed Issue 43434:

    Upgrading VMware SD-WAN Edges in a High Availability topology from 2.x to 3.x takes up to 25 minutes to complete.

  • Fixed Issue 43472:

  • Issue 44640:

    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:
