Migrating CRS125-24G-1S-RM from master-port to bridge

RouterOS General

Hi,

I have CRS125-24G-1S-RM running on 6.40.8 firmware, and it has 4 master ports. I want to update it to 6.42.9. But 6.42.9 has no “master-port” option, it uses bridges and hardware offloading. What I need to migrate to new firmware? Can I simply create 4 bridges and enable hardware offloading for all ports in these bridges?

/interface ethernet
set [ find default-name=ether2 ] comment=WAN
set [ find default-name=ether3 ] arp=proxy-arp comment=Master1
set [ find default-name=ether4 ] master-port=ether3
set [ find default-name=ether5 ] master-port=ether3
set [ find default-name=ether6 ] master-port=ether3
set [ find default-name=ether7 ] master-port=ether3
set [ find default-name=ether8 ] master-port=ether3
set [ find default-name=ether9 ] master-port=ether3
set [ find default-name=ether10 ] master-port=ether3
set [ find default-name=ether11 ] comment=Master2
set [ find default-name=ether12 ] master-port=ether11
set [ find default-name=ether13 ] master-port=ether11
set [ find default-name=ether14 ] master-port=ether11
set [ find default-name=ether15 ] comment=Master3
set [ find default-name=ether16 ] master-port=ether15

Only ports members of one bridge can have HW offloading active. All the rest will be handled through software.

The new way of doing it is to configure single bridge … for separation configure different VLANs, one VLAN per master port. To keep all switching in hardware, configure VLANs through /interface ethernet switch.

Thank you for your reply. But it’s vary sad…

It’s a change to how you need to operate. Sad in the short term I agree but once you adjust your working methods. It will become second nature as it currently is.
