Hi,
New to MT. Just got a Hex Refresh,
The Refresh got an internal switch MT7621 capable of VLAN decoding. https://help.mikrotik.com/docs/spaces/ROS/pages/15302988/Switch+Chip+Features
I have a setup where I configured port 1 to WAN and Port 2 as LAN with 2 sub vlan, BASE and GUEST.
/interface ethernet
set [ find default-name=ether2 ] name=LAN
/interface vlan
add interface=LAN name=BASE vlan-id=19
add interface=LAN name=GUEST vlan-id=15
With this setup, am I using the MT7621 for VLAN decoding ? Do I need to create a bridge to use the MT7621 for hardware decoding ?
Just follow one bridge setup and you’ll be fine.
Vlan attached to bridge.
ROS will take care of hw offloading in background.

One bridge, and the bridge has no subnet, does not do dhcp.

If you only require the VLANs on a single port the configuration arrangement is fine as-is.
The hardware offloading on the smaller Mikrotiks is only L2 / ethernet switching for packets between bridge ports within the same VLAN, any traffic between different VLANs or between a VLAN and the WAN is always handled by the CPU.

I just found a 0 that probably fell down from anav’s post , the suggested link should be:

Yikes! Much thanks for that.
