Virtual Extensible LAN (VXLAN) is a proposed encapsulation protocol for running an overlay network on existing Layer 3 infrastructure. If servers with traditional hypervisor are deployed into VXLAN network, the VXLAN gateway (as Figure 1 shows) is required to be enabled on access switch to forward traffic between VXLAN and traditional VLAN network. To make VXLAN gateway working, users must configure the mapping between VXLAN and VLAN. If there are many VXLAN gateways, then it would be large workload for network administrator. If a VM is migrated to another server, the VXLAN-VLAN mapping need to be configured on the access switch to which the destination server connects, otherwise the service provided by the VM would be disrupted.

Figure 1 VXLAN Gateway

Edge Virtual Bridging (EVB, 802.1 qbg) describes the technologies and protocols that are being standardized to ease the coordination and management issues faced by virtualized servers at the server-network edge.

This disclosure implements a method to configure the VXLAN-VLAN mapping automatically on VXLAN gateway in EVB environment.

Virtual Station Interface (VSI) is an interface to a virtual station that is attached to a downlink relay port (DRP) of an edge relay, which is declared inEVB. A VSI instance is named a VSI type, it can be defined with a set of network policies, such as VLAN, ACL, QOS and so on, which is identified by VSI type ID (TPID). When a VM that is attached to a VSI gets association to an access switch, the switch will apply the network policies defined in corresponding VSI type to the traffic of the VM.

Assume that VXLAN gateway is enabled by default on the access switch and the VXLAN gateway enabled access switch will be named VXLAN gateway in the following description. The ports of VXLAN gateway can be...
