Bonding Beginner

Wed May 18, 2022 9:17 am

Hello,

New owner of Mikrotik CRS328-24P-4S+ units and I am attempting to configure port bonding. I read the documentation and attempted the commands below but it gave me an error?
[admin@NEWCORE] /interface bonding> add mode=802.3ad name=bond_15-16 slaves=ether15,ether16 
failure: ether15 already in bridge
I am obviously missing something simple, so could a kind person help me get back on track.

Thanks, Mark

Sometimes, reading the error line, it suggests the solution:
failure: ether15 already in bridge

Now check inside
/interface bridge port print
if ether15 is present

Now check inside
/interface bonding print
if ether15 is present on another bonding

The error message indicates you exactly what the problem is.
The port members of a bonding must not be slave interfaces of the Bridge itself. When you create the Bond interface, add that bond to the Bridge.

Thank you rextended and Zacharias, I understand my question was probably frustrating. First time owner of Mikrotik, so I will get there eventually.

Here's the results...

Remove ports ether1 and ether2 from the Bridge.
Then create the bonding interface with ports ether1 and ether2.
Finally, add the bonding interface to the Bridge.

As simple as that...

But the question is... That synology is capable to do bonding?

If a peripheral has multiple Ethernet ports, it doesn't necessarily mean they can be bonded together...

Looks like DS416play or alike. If so, it can do bonding.
Most current devices are running DSM7 nowadays.
