3. Set the local IP Address that can be used as a source for VXLAN tunnels.
VXLAN-INSTANCE mode
local-vtep-ip IP Address
4. Create a VNI profile to associate with remote VTEP configuration.
VXLAN-INSTANCE mode
vni—profile profile name
5. Associate VNID to the VNI profile.
VNI-PROFILE mode
vnid VNID Range
6. Create a remote tunnel and associate the remote VTEP to the VNID.
VXLAN-INSTANCE mode
remote—vtep—ip remote IP Address vni-profile profile name
7. Enable the VXLAN.
VXLAN-INSTANCE mode
no shutdown
8. Enable VXLAN instance on the interface. The interface should not be on layer 2.
INTERFACE mode
vxlan-instance Instance ID
9. Associate VNID to VLAN.
INTERFACE VLAN mode
vxlan-vnid VNID
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.
NOTE:
When more than 15000 learned MAC addresses are synchronized from the Nuage controller to one of the VTEPs,
the SSL connection between the controller and the VTEP flaps continuously.
Displaying Static VXLAN Configurations
To display the static VXLAN configurations, use the following commands.
The following example displays the basic configuration details.
DellEMC# show vxlan vxlan-instance 1
Instance : 1
Mode : Static
Admin State : Up
