Hi!

I need to mirror the traffic of a device, that is connected to two Arista 7050QX which are building an "MLAG-Cluster".

Do you know, if this is possible?
How can this be done?

- Mirror the Ethernet-Interface on each switch?
- Mirror with one port?

Thank you for your help!!

Yes, it's call a span port in Arista. You can't span across an MLAG, so you'll have to span the underlying members of the port channel.

From there you can dump it to a tap aggregator.
