RouterBOARD 750G r3 no HW Offload ?

RouterOS General
1

hi,
I am running dude on a RouterBOARD 750G r3.
Although it look like the device is capable to do hw offload it seems not to work …

system routerboard print 
       routerboard: yes
        board-name: hEX
             model: RouterBOARD 750G r3

there is no H on the interfaces …

any suggestions ?

All the bridge ports but one are inactive… what happens if you connect another cable to one of the unused ports? The HW offload means forwarding of frames among ports by the switch chip itself.

I had port 5 connected and the H was not there …

4

No more ideas then. There is nothing in the configuration which would explain that.

I do see the same as you .

Set STP on the bridge to none.

somehow setting STP on the bridge to none made the H appear …
but WHY ? all my other type of devices are running RSTP and do show the H …

My STP was set to none and showing no Hardware Offload.
Did try to change to STP stil no HW, then back to none, still no HW

I saw you have a PVID assigned on a port. Are you using VLAN filtering in your bridge? If so, that’s the culprit. See the table here: https://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_Hardware_Offloading. The 750GR3 uses the MT7621 chip.

Yes I do use VLAN, did forget abut this table :slight_smile:

tnx for pointing to this documentation.
I think I can live with no HW acceleration on my local dude server …
