MLAG configuration in CRS326-24s

Mon Mar 11, 2024 8:30 pm

Hi all.

I'm new to the Mikrotik universe and I'm trying to configure MLAG with two devices.

I am doing all the steps in the post: https://help.mikrotik.com/docs/display/ ... tion+Group

But when I run the last step in "/interface bridge mlag" to create mlag it shows the message: "not hw offloaded".

Is this because hw-offloading needs to be disabled?

I tried with this command and the message does not change:

/interface/ethernet/switch set 0 l3-hw-offloading=no
/interface/ethernet/switch/port set [find] l3-hw-offloading=no

Does anyone have any idea what I should do?

thanks

Hi o/,
same with 2x CRS518 and routeros 7.14.1
[admin@CRS02] > /interface/bridge/mlag/print   
         ;;; not hw offloaded
     bridge: bridge1
  peer-port: bonding1
[admin@CRS02] > /interface/bridge/mlag/monitor 
      ;;; not hw offloaded
  status: disabled

[admin@CRS02] > /interface/ethernet/switch/l3hw-settings/monitor
;;; L3HW is not running
Activating or deactivating hw offloading on the switch chip has no influence on the message. Off should be correct according to the documentation.
I'm not sure what ";;; not hw offloaded" means if off is correct?

But when I run the last step in "/interface bridge mlag" to create mlag it shows the message: "not hw offloaded".

The answer is in the first caution box on the documentation page you linked to: "The MLAG is not compatible with L3 hardware offloading. When using MLAG, the L3 hardware offloading must be disabled."

But isn´t it disabled when it looks like this? Or is there a different off switch for "L3 hardware offloading"?

The problem seems to have been related to the bond.
If I don't do the MLAG synchronisation on the bond, it works.
