Another one we have been discussing between colleagues a while ago:
Imagine: VC with two members
Two devices (server or switch) connected with a LAG to both members.
Device A has sent a packet on its first link of the LAG, with destination device B
Then my question:
* will the member that received the packet send it always out via his direct link to device B
(take local LAG port)
* there is a possibility that the packet will be sent out to the other member (on VCP or fiber) and then to device B
(because the hashing algorithm could decide that the packet should be on the certain port of the LAG, which could be on another member)
And even more difficult: how can we verify this?

On the EX4200 VC, the egress port is determined by the ingress hash, so the data could exit either a local port or a port on another VC member.
