VMware Cloud Director Availability™ 4.2.1 | 12 AUG 2021 | Build 18422625 (Product version: 184.108.40.20610807-98aa4437ed)
Check for additions and updates to these release notes.
What's in the Release NotesThe release notes cover the following topics:
VMware Cloud Director Availability 4.2.1 now supports NSX Data Center for vSphere in addition to NSX-T Data Center support for Stretching On-Premises Layer 2 Networks, with some operations* caveats and limitations.
This VMware Cloud Director Availability release also includes several resolved issues and updates of third-party libraries that provide security fixes.
VMware Cloud Director Availability 4.2.1 supports an in-place upgrade directly from versions 220.127.116.11, 18.104.22.168, 4.1.1, and 4.2. For more information, see Upgrading in the Cloud and Upgrading On-Premises.
Caveats and Limitations
* The Layer 2 VPN sessions have the following limitations in VMware Cloud Director Availability 4.2.1:
|NSX Edition||Can Stretch Routed Type Networks||Can Stretch Isolated Type Networks||Can Stretch Direct Type Networks|
|NSX-T Data Center||Yes||Yes, for NSX-T Data Center 3.1 and later||No|
|NSX Data Center for vSphere||Yes**||No||No|
** NSX Data Center for vSphere stretches only routed networks with interface type subinterface, not with interface type internal nor distributed.
** NSX Data Center for vSphere can stretch VXLAN and VLAN OrgVDC routed networks only connected to the trunk interface, and cannot stretch networks connected to the uplink nor to the internal interfaces. Guest VLAN Allowed must not be selected. If at some point Guest VLAN Allowed was selected, recreate the network from scratch.
- In more than one L2 VPN session, do not attempt to use/add the same organization VDC network, or a network segment, or in NSX-T it causes the following error message: Tunnel ID specified for L2 VPN [list] is already used by...
- The Autonomous Edge cannot distinguish between networks with the same vlan id. Editing the client L2 VPN session and switching from one on-premises network to another with the same vlan id is not reflected in the VMware Cloud Director Availability interface and the original network is still shown as stretched.
- Stretching on-premises standard switches port groups is not supported. Only DVS port groups are supported for stretching.
- One Autonomous Edge supports only one client L2 VPN session, stretching a maximum of 14 networks.
Note: The VMware Cloud Director Availability vSphere Client Plug-In requires vSphere Client support. With earlier vSphere versions, to configure replications use the VMware Cloud Director Availability Portal.

- Cannot display the MAC addresses in VM view for on-premises to cloud replications
In VM view, after creating an on-premises to cloud replication, when attempting to change the network settings you cannot see the MAC addresses listed next to the network interfaces.
- Changing the SLA profile does not update the retention policy settings
After changing the SLA profile from either Silver or Gold to an SLA profile that only preserves the latest instance, for example, Bronze, the retention policy settings do not update with the defined in the SLA profile.
- Changing the SLA profile of a replication applies retention policy but does not associate the updated SLA profile with the replication
After changing the SLA profile of a replication, the retention policy of the new SLA profile applies but the updated SLA profile does not associate with the replication and the SLA profile column displays N/A.
- Tenants cannot start new outgoing replications by using multisite authentication to 4.2.x sites using VMware Cloud Director 10.2 or later
Starting new outgoing protection or migration as a tenant when using multisite authentication to extend the session to destination sites using VMware Cloud Director Availability 4.2.x and VMware Cloud Director 10.2 or later, completes the task with an error
The provided credentials are not valid.message. This issue does not affect the service providers.
Workaround: Log in to the destination site and configure the same replication as an incoming one.
- Error when using the uplink IP address of the Edge Gateway when creating the server L2 VPN session
Attempting to use the uplink IP address of the NSX-V Edge Gateway when creating the server L2 VPN session results in the following error message.
IP Address is not within allowed range(s)
- In VMware Cloud Director, create an IP Address range for the Edge Gateway. This range must include the uplink IP address of the Edge Gateway, allowing VMware Cloud Director Availability to recognize the IP address as a valid one and allowing the creation of the server L2 VPN session.
- Alternatively, upgrade to VMware Cloud Director Availability 4.3.
