Hi all,

I setup the above devices for port trunking. The following devices are connected to the DGS:
6 Workstation, Printer, 2 Ports for QNAP, Fritzbox. All Ports are set to Auto Speed.

QNAP: Port Trunking / Managed Switch / 802.3ad dynamic / Mac+IP

DGS (Firmware 6.10.xxx) : The device was configured as described here: https://eu.dlink.com/uk/en/support/faq/switches/layer-2-gigabit/dgs-series/uk_dgs_1210_configure_link_aggregation_lacp

Unfortunately I only get a max download bandwidth of 30GB/s. And it takes minutes for the contents of a folder to be displayed.
Even the Internet connection via the DGS is extremely slow.
I tested the speed by connecting one device directly with the Fritzbox. Speed as expected.

Looks like the DGS slow down my network traffic.
What did I miss? Any Ideas? Is there a best practice for setting up such a switch?

Regards Lutz

Any progress on this?

30Gbs? Do you mean 30Mb?
