LACP between 2 switch in SwOS

Fri Sep 30, 2022 10:09 pm

Hi,

In our datacentre we have 2x CRS317-1G-16S+RM for full redundancy. We have a server that has 2x 10G port that we would like to bound in a LACP.
Could anyone please tell me if this is possible between 2 Mikrotik swicth in SwOS? I know If we use a single switch it isn't an issue but can it be done with 2 separate switches?

Thank you all in advance

If I get what you are wanting to do, I don't think so. If you figure it out, I have a perfect use of that concept myself.

You can only have LACP to multiple switches if they implement MLAG. Not available in SwOS, but CRS3xx/CRS5xx/CCR2x16 devices running RouterOS 7 do https://help.mikrotik.com/docs/display/ ... tion+Group

Did a quick read on the manual page that tdw linked. Would be nice to have that in SwitchOS one of these days... I'm not swapping out my CSS326 switches in order to get it however.

Hi,
Do I need to run this cmd on the switch or is it just how to do it in a non mlag setup?
/interface bonding
add mode=802.3ad name=bond1 slaves=sfp-sfpplus1,sfp-sfpplus2
I have 4 pair of lacp group to create, do I set them all to vlan 1 or do they need their own vlan?
# Peer1
/interface bridge vlan
add bridge=bridge1 tagged=sfp-sfpplus1 vlan-ids=1
 
# Peer2
/interface bridge vlan
add bridge=bridge1 tagged=sfp-sfpplus1 vlan-ids=1
