cat5-cablesNow that the switch is configured for Jumbo Frames, I've setup the LACP trunk and configured the relevant VLANs I now need to configure my XPEnology NAS with a bonded network interface using LACP.

Login to your NAS web interface  at http://<your-nas-ip>:5000 and go to Control Panel, Network, Network Interface, Create, Created Bond...

Double check that the interfaces you've selected in Synology DSM tie up with the correct physical NICs and that those physical NICs are patched into the correct switch ports, (e.g. the ones configured as a LACP trunk).

You should see that the interface comes online as Bond 1...
