service type vxlan-tunnel

Function

The service type vxlan-tunnel command configures an Eth-Trunk as a VXLAN loopback interface.

The undo service type vxlan-tunnel command cancels the configuration.

By default, an Eth-Trunk is not a VXLAN loopback interface.

Only the S6720-EI and S6720S-EI switches support this command.

Usage Guidelines

Usage Scenario

The S6720-EI and S6720S-EI switches can decapsulate received VXLAN packets and forward them at Layer 3 only after a VXLAN loopback interface is configured on them. As a result, you need to configure an Eth-Trunk as the VXLAN loopback interface when the S6720-EI and S6720S-EI switches function as the Layer 3 VXLAN gateway.

Follow-up Procedure

Run the trunkport command to add member interfaces to the VXLAN loopback interface.

Precautions

After an Eth-Trunk is configured as a VXLAN loopback interface, STP is automatically disabled on the Eth-Trunk. The Eth-Trunk then does not support STP configuration commands. After the configuration is canceled, STP is automatically enabled on the Eth-Trunk.
Only one Eth-Trunk on a switch can be configured as the VXLAN loopback interface. VXLAN packets from all VBDIF interfaces are encapsulated and decapsulated by this loopback interface.
An Eth-Trunk containing member interfaces cannot be configured as a VXLAN loopback interface.
The configurations allowed on an Eth-Trunk to be configured as a loopback interface include description, enable snmp trap updown, jumboframe enable, mixed-rate link enable, qos phb marking enable, set flow-stat interval, shutdown, local-preference enable, traffic-policy (interface view), and trust. If other configurations exist on the Eth-Trunk, the Eth-Trunk cannot be configured as a loopback interface.
After an Eth-Trunk is configured as a loopback interface, the Eth-Trunk supports only the following configurations: authentication open ucl-policy enable, description, enable snmp trap updown, jumboframe enable, mixed-rate link enable, qos phb marking enable, set flow-stat interval, shutdown, local-preference enable, statistic enable (interface view), traffic-policy (interface view), vcmp disable, and trust.
Before running the undo service type vxlan-tunnel command, delete all the member interfaces of the Eth-Trunk interface and all VBDIF interfaces on the device.
