I wanted to say thank you to all of those who have offered us (both on-
and offlist as well) help and support for this arista move.
It feels good to know that with it, we are on a path that many here are
walking on.
Lastly, if I may, one more question:
My arista seller tells me that the arista 7050QX-32S supports 10G fiber
uplinks, but I need 10G UTP RJ45 uplink to our HP core switch. (our HP
has 1G fibers, and a 8 * 10G UTP RJ45 linecard.
They tell me that the 7050QX-32S can do UTP RJ45, but only 1G speed, and
not 10G. :-( Is that something that the (many) arista experts here can
confirm or deny..? (other than: "You need to buy it, and then try it")
Thanks!

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
!

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
