New and Changed Features

The features listed in this section are new or changed as of Contrail Networking Release 1910. A brief description of each new feature is included.

Encryption Support Between Analytics API Servers and Client Servers

Starting with Contrail Networking Release 1910, the connection between Analytics API servers and Client servers is encrypted with SSL. The Clients servers connect to the Analytics API server through the REST API Port. In earlier releases, the connection between Analytics API server and the Clients servers was not encrypted, which could pose a security threat.

For more information, see Encryption Between Analytics API Servers and Client Servers.

Enhanced Routing Policies to Support Modification of Secondary Routes in Virtual Networks

Starting with Contrail Networking Release 1910, virtual network routing policies are automatically applied to secondary routes. This feature is especially useful as a mechanism to modify routes imported from MP-BGP, including routes that are imported from the MPLS network, using routing policies.

For more information, see Routing Policy.

Support for Aborting Ongoing Jobs in Contrail Networking Fabric

Starting with Contrail Networking Release 1910, you can use the Contrail Command user interface (UI) to abort an ongoing fabric job at any stage. In earlier releases, an ongoing fabric job could not be aborted from the Contrail Command UI.

For more information, see Aborting Ongoing Fabric Jobs.

Support for Integrating VMware with Contrail Networking Fabric

Contrail Networking Release 1910 supports integrating VMware with Contrail Networking fabric. A dedicated Contrail vCenter Fabric Manager (CVFM) plugin is deployed for this integration. This plugin is deployed when you install Contrail Command. You can then enable this plugin when you provision Contrail Command. However, if you do not enable this plugin during provisioning, you can enable the plugin from the Infrastructure>Cluster page of the Contrail Command UI.

Note:

VMware-Contrail Networking Fabric integration supports only brownfield device discovery. Greenfield device discovery is not supported.

For more information, see Understanding VMware-Contrail Networking Fabric Integration.

Support for Monitoring DPDK Enabled Bond Interfaces

Starting with Contrail Networking Release 1910, you can use the Contrail Command user interface (UI) to monitor and view the details of master and slave devices that are members of a bond interface. This feature is available for device systems configured with Data Plane Development Kit (DPDK). In earlier releases, you could only see a bond interface in the Contrail Command UI.

For more information, see Monitoring Bond Interfaces in DPDK Enabled Devices.

Support for Trunk Networking Between Contrail Networking and Neutron

Starting with Contrail Networking Release 1910, Contrail integrates with Neutron trunk port APIs, which enables trunk networking between Contrail and Neutron instances. Trunk networking uses trunk extension that is used to multiplex incoming and outgoing packets from multiple Neutron logical networks using a single Neutron logical port. A trunk extension is integrated in Neutron as a collection of Neutron logical ports. In the trunk extension that is implemented, Contrail introduces logical entities defined by OpenStack Trunk API to provide backend support for Neutron Trunk Port API. The Neutron Trunk Port object maps to Contrail Virtual Port Group (VPG) object, which was designed for handling non-LCM BMS workflow and multi-VLAN support.

Support for QFX5120-32C Devices in Lean-Spine Deployments

Starting in Contrail Networking Release 1910, a QFX5120-32C device can be used in lean-spine deployments.

For more information on supported hardware platforms and associated roles, see Supported Hardware Platforms and Associated Node Profiles and Roles.

Viewing Overlay Route Information

Starting with Contrail Networking Release 1910, you can view control node and compute node information using Contrail Command. To view control node information and to see a graphical representation of the overlay routes navigate to the Infrastructure > Cluster > Cluster Nodes page. The cluster infrastructure components, including the numbers of control nodes, compute nodes, analytics nodes, config nodes, and database nodes currently operational and also virtual networks are displayed. Click the control and compute node tabs for more information on the nodes. Alternatively, navigate to the Monitoring > Dashboards page to view more information as well as graphical representations of control and compute nodes.
