Hello MJ, Arista has a good documentation available for example at https://www.arista.com/en/um-eos/eos-multi-chassis-link-aggregation or https://eos.arista.com/mlag-basic-configuration/. Don't worry, when you know what exactly you want to configure, it's just a few lines of config in the end. It's more or less: On Both Switches: ------------------------- no spanning-tree vlan-id 4094 ! vlan 4094 trunk group mlag ! interface Port-Channel2000 switchport mode trunk switchport trunk group mlag ! interface Ethernet35 description MLAG link channel-group 2000 mode active ! interface Ethernet36 description MLAG link channel-group 2000 mode active ! On switch 1 in addition: ------------------------------- interface Vlan4094 ip address 10.2.0.1/30 ! mlag configuration domain-id mlag local-interface Vlan4094 peer-address 10.2.0.2 peer-link Port-Channel2000 ! On switch 2 in addition: ------------------------------- interface Vlan4094 ip address 10.2.0.2/30 ! mlag configuration domain-id mlag local-interface Vlan4094 peer-address 10.2.0.1 peer-link Port-Channel2000 ! After that you create port-channels for the ports you like to bundle with a specific mlag id On both switches as an example: --------------------------------------------- interface Port-Channel1 switchport access vlan 101 mlag 1 ! interface Ethernet7/1 description "MLAG bonding to Server XXX" channel-group 1 mode active ! -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@croit.io Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Sa., 20.

Hi,
Just to follow-up this dialogue:
After Martin's tip for the arista's, we started looked around, and while buying from ebay did not appeal to us, we did manage to find a couple of refurb equipment resellers that offer them for a (little) bit more, but then including a year warranty.
And actually, for an extra 175 euro, I was able to upgrade warranty from one to three years.
Now I just need to get an ok from management here. And then the fun begins: start reading up on arista EOS MLAG config, en doing a lot of testing with new stuff.
Now I wonder if it's accepted to ask arista-specific (MLAG) config questions here on this list...
Have a nice weekend all!
MJ
