Configuring Port Trunking on a Buffalo TeraStation 5010/3020/3010/6000/5020/3030/7010 series

Last Updated: 09/08/2025

1. Open Settings and click on the "Network" tab.
   
2. Click on the configuration button next to "Port Trunking".
   
3. At the Port Trunking drop-down, select "Ethernet 1 and 2". (If you are working on a 51210 model TeraStation, you will have the option for more than one trunking group)
   
4. Click on "Bond 1". (If you are working on a 51210 model TeraStation, you will have the option for more than one bond.)
   
5. Select the trunking mode from the drop-down menu. This should be the same as the trunk mode set on the switch for the ports this unit will be using.
   
6. Once you have the options set as desired, click OK. The example is a TS5810 series unit. If you are using a TS51210 series you will have more ports available and can create multiple trunks
   
7. Click OK to confirm the configuration change.
   
8. Restarting the TeraStation is required to apply the changes. Click Yes when you are ready to restart the TeraStation.
   
9. The process is finished after the TeraStation restart. The trunk will assume the IP address of the lowest numbered port in the trunk.
