UDC Leaf (EA) - Release plans

This article details the high-level current features of the UDC Leaf product, how those features will evolve as we move closer to General Availability (GA) for the UDC Leaf and Spine switches, and current limitations in functionality.

Current high-level features

The UDC Leaf (EA) has a powerful feature set, with many common L2 switching features as well as VXLAN encapsulation for data center applications. VXLAN can be used either with two UDC Leaf switches connected to each other or an L3-capable router or switch acting as a Spine switch in the middle.

Note that, at this stage, UDC Leaf is only compatible with IPv4, not IPv6.

Full functionality is documented in the command line interface (CLI) guide.

Upcoming focus areas for releases

UniFi Data Center will have a fully-featured 100 GbE Leaf and Spine switch solution. We plan to release the UDC Spine switch as well, with L3 features such as dynamic routing. Together, UDC Leaf and Spine will support full data center networks, including support for EVPN VXLAN networks.

Known limitations

There are a few known limitations in support with the current UDC Leaf functionality. We plan to update this table as we move closer to a final release. See below for details.

Limitation Implications
2 VTEP networks: Each VNI can only span 2 VTEPs Applications requiring VNIs across more than 2 endpoints are not supported
Command port-channel min-links: Not currently supported Current min-link number must be 1
Spanning tree: Only works for physical ports Spanning tree for LAGs and VLANs currently not supported
LAG interfaces: Only works for physical ports LAG for VLANs currently not supported
Speed setting: Setting speed on a port results in the same speed being set for a cluster of 4 ports Speed must be the same on each cluster of 4 ports (e.g., 1-4, 2-8)
Speed setting: Auto-negotiation sometimes does not detect 25G Speed should be set manually for 25G connections
