Important Notes

SFP module testing during the COVID-19 pandemic

Due to the ongoing COVID-19 crisis, the VMware Quality Engineering teams across the world have been forced to shelter in place. For the standard Release Qualification process, remote access to our worldwide set of test laboratories has ensured the same level of testing and quality as every other VMware SD-WAN software release. 

However, the testing of SFP modules requires a physical presence in the laboratory to enable testing the full combination of modules and VMware SD-WAN Edge models. As a result, only a subset of SFP module testing has been performed in Release 3.4.1. Please note that there have been no changes to the operator system or drivers that could cause SFP modules to not work as expected.  Also, no issues were observed during the subset of SFP test cases the teams were able to execute.

VMware Edge 510-LTE configurations on CELL1

Release 3.4.1 resolves an issue where a VMware SD-WAN Edge 510-LTE could lose connectivity on CELL1 interfaces after upgrading the Orchestrator to Release 3.4.0 and making a Device Settings change. 

The release also addresses a specific VMware SD-WAN Orchestrator upgrade issue where the Profile configuration of Edge 510-LTE devices using Release 3.3.2 P1 and below would not be copied over to the new Edge 510-LTE model family configuration on the same Profile. This issue is resolved in this release by copying the Edge 510 Profile model configuration into the new Edge 510-LTE model family.

The resolution for this issue means that any Edge 510-LTE configuration that was customized at the profile level between the initial rollout of Release 3.4.0 and Release 3.4.1 will be lost and will reflect that of the latest existing 510 model configuration on the same configuration profile.  As a result, Edge 510-LTE specific configurations made at the profile level between the Orchestrator upgrade to Release 3.4.0 and Release 3.4.1 will need to be manually restored by the user.

Note: Any Edge level configurations (using Edge override) of an Edge 510-LTE will persist through the upgrade. This includes LTE modem configurations made at the Edge 510-LTE level.

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).

New Features

Note: Beginning with Release 3.4.0, VMware SD-WAN has adopted a standardized set for release numbering: Major.Minor.Patch. Typically, patch releases are reserved for bug fixes and do not introduce new features. However, the ongoing COVID-19 Pandemic has resulted in an overwhelming number of urgent customer requests for the below feature. The introduction of the Private Segments feature in a patch release reflects these exceptional circumstances.

Private Segments

Segments can now be marked as Private. When a segment is marked as Private, there are two functional changes that take place:

  1. Flow statistics for this segment are not sent to the VMware SD-WAN Orchestrator. This allows administrators to create segments (for instance for Work at Home users) which do not give a user's employer visibility into the flows that are traversing the private segment. 
  2. Flows on private segments will not use the VMware SD-WAN Gateway to access the Internet—even if the flow matches a Business Policy configured with “Internet Multipath”. This is because without visibility into flow statistics, VMware SD-WAN is not able to fulfil the audit obligations required in case of improper behavior of user flows. 

Note: For partners operating their own SD-WAN Partner Gateways, configuring NAT routes as secure will still allow Private Segment traffic to exit at the Gateway. Partners are responsible for managing the decision on whether to allow this traffic to traverse their Gateways using these settings.
