CRS326 and bonding

[csi]

Hello,

I’ve tried to configure Bonding interfaces on the CRS326 based on the wiki entry:
https://wiki.mikrotik.com/wiki/Manual:CRS3xx_series_switches#Bonding

When I try to add the ether interfaces to the bridge, I get the following error message:

failure: ether2 is already slave

I’m using RouterOS Version 6.42rc37. Is this a bug?


Many thanks in advanced.

did you start with an empty config?

did you start with an empty config?

Sure. Unboxing, updating and then testing.

Did you tried to add the bonding interface to bridge, instead of ethernet interface, right?

In the wiki link, ether1 and ether2 are inside bonding, and bonding goes inside the bridge.

Add the bonding interface to the bridge is not the problem. But until the ether interfaces are not be able to add, the whole config is not related to HW-offload, which is the goal for the expected configuration. Many thanks for the hint.

Once you add bonding to bridge, automatically you have hw-offload, I guess. The ethernet interfaces are under the bonding.

I’m not sure if this is right. Because the documentation on the Wiki says I have to add the ether interfaces to bridge also to user HW-offload. When I add the bond interface only, the “H” tag is missing and then it looks that the bonding interface is handled by the CPU instead of the hardware.

Has you tried to configure this too?

Today I have tried to add a device to the bonding interface. It does not work unfortunately. So I think LACP is currently no useable feature on CRS326. Hopefully a fix would be available soon.

That isn’t a blank config. That’s a factory config. I can’t remember exactly but on a CRS125 ether1 was WAN and ether2-24 were switched with ether2 as a master.

Try completely resetting the switch ensuring you tick “no factory defaults” (or similar) and then configure from scratch, bonding is refreshingly easy with MikroTik.

Sure, but the basic setup is just one bridge with default IP address and all interfaces added to that bridge. No WAN, no other settings.

It looks there are some more problems on my CRS326 regarding bonding devices:

With 6.42rc39 bonding interfaces are available and working fine. Only one issue regarding MTU size is still open.
