Usage guidelines 

A VSI acts as a virtual switch to provide Layer 2 switching services for a VXLAN on a VTEP. A VSI 
has  all functions of a  physical  Ethernet switch, including source MAC address learning, MAC 
address aging, and flooding.  

A VSI can provide services only for one VXLAN. 

Examples 

# Create VSI 

vxlan10

 and enter VSI view. 

<Sysname> system-view 

[Sysname] vsi vxlan10 

[Sysname-vsi-vxlan10]  

Related commands 

display l2vpn vsi 

vxlan 

Use 

vxlan

 to create a VXLAN and enter its view, or enter the view of an existing VXLAN. 

Use 

undo vxlan

 to restore the default.

 

Syntax 

vxlan vxlan-id 

undo vxlan 

Default 

No VXLANs exist. 

Views 

VSI view 

Predefined user roles 

network-admin 

Parameters 

vxlan-id

: Specifies a VXLAN ID in the range of 0 to 16777215. 

Usage guidelines 

You can create only one VXLAN for a VSI. The VXLAN ID for each VSI must be unique. 

Examples 

# Create VXLAN 10000 for VSI 

vpna

 and enter VXLAN view. 

<Sysname> system-view 

[Sysname] vsi vpna 

[Sysname-vsi-vpna] vxlan 10000 

[Sysname-vsi-vpna-vxlan-10000] 

Related commands 

vsi 

vxlan ip-forwarding 

Use 

vxlan ip-forwarding

 to enable Layer 3 forwarding for all VXLANs.
