TRB140 Devices
The information in this page is updated in accordance with firmware version TRB1_R_00.07.10.2.
VXLAN
Virtual Extensible LAN is a tunneling interface protocol (VXLAN), which allows VXLAN layer 2 virtualization over layer 3 network. VXLAN establishes a logical tunnel between the source and destination network devices, through which it uses MAC-in-UDP encapsulation for packets. In addition, it helps customer sites to configure layer2 VPN.
Note: VXLAN is additional software that can be installed from the System → Package Manager page.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.
Device configuration
The Device configuration section is used to set up VXLAN devices.
To add a new device - select 'VXLAN' and click 'Add' button:
After clicking 'Add' you will be redirected to the newly added VXLAN device configuration page.
Configuration
| Field | Value | Description |
|---|---|---|
| Name | string; default: vxlan1 | Name of the device. |

| PORT | integer [1..65535]; default: 4789 | VXLAN network identifier. |
| Local address | ip; default: none | Sets the local source IP address for VXLAN tunneling. |
| Remote address | ip; default: none | Specifies the multicast group or remote IP address used for VXLAN tunneling. |
| Ageing | integer [1..4294967295]; default: empty | Specifies the lifetime in seconds of FDB entries learnt by the kernel. |
| Max FDB entries | integer [1..4294967295]; default: empty | Specifies the maximum number of FDB entries. |
| IPv4 checksum | off | on; default: off | Specifies if UDP checksum is calculated for transmitted packets over IPv4. |
| Learning | off | on; default: off | Enables or disables MAC learning for VXLAN. |
| Proxy | off | on; default: off | Enables or disables ARP proxy for VXLAN. |
| RSC | off | on; default: off | Specifies if route short circuit is turned on. |
| L2miss | off | on; default: off | Specifies if netlink LLADDR miss notifications are generated. |
| L3miss | off | on; default: off | Specifies if netlink IP ADDR miss notifications are generated. |
| IPv6 TX checksum | off | on; default: off | Enables or disables UDP checksum calculation for transmitted packets over IPv6. |
