Limitations on VXLAN

While configuring a VXLAN, the following conditions apply:

• Hybrid ports are not supported in VXLAN (hybrid port means an interface tagged to one VLAN and untagged to another VLAN).
• The show vxlan vxlan-instance statistics remote-vtep-ip and the show vxlan vxlan-instance statistics instance commands are not supported in a NSX environment.
• VXLAN is not supported in a stacking setup.
• VXLAN with VRF configuration is not supported.
• Routing over VXLAN is not supported in a controller-based VXLAN setup.
• SNMP and REST API are not supported for VXLAN configurations.
• Multicast over VXLAN is not supported.
• In multicast and broadcast traffic, even though the remote VTEP is reachable through the ECMP path, load balancing is not supported.
• Only one Remote VTEP can be reached through a single interface in a broadcast domain.
• Single VNI can be mapped to Single VLAN in both static and NSX controller-based VXLAN. Hence, only 4000 VNIs are supported while configuring static VXLAN.
• You can map multiple VNIs with multiple VLANs in an NSX-based VXLAN.
• You can configure only one Nuage controller in a VXLAN setup. Nuage controller datapath-learning is not supported.
• In a Nuage controller-based VXLAN deployment, station moves of non-virtualized entities may not work as expected due to a possible issue in the Nuage contoller.
