Virtual Link Static Bidirectional Association

Virtual Link Extension (VLE) static bidirectional association is between a physical port or trunk and a VXLAN tunnel for a selected VNID. Every virtual link extension is defined using a VLAN or VXLAN VNID and adding physical ports or trunk and tunnels to this VLAN or VXLAN VNID. One endpoint of virtual link extension must be a physical port or trunk and other end point must be a virtual tunnel end point (VTEP). A VTEP can carry multiple VLE VLANs or VXLANs.

VLE VLANs are created using a special VXLAN mode called “transparent” which prevents flooding and learning on VLE VLANs in the switch. Packets are sent directly between a physical port or trunk and the VLE part of VLE regardless of traffic types. There is no BPDU processing for VLE VLAN.

VLE VLANs are now enhanced to provide the capability of adding and removing ports, as well as assigning or modifying trunk ports. Note that when a trunk carrying a VLE VLAN is deleted, Netvisor One removes the VLE VLAN  from the trunk members to avoid any hardware inconsistencies.
