Hi!
I really need help...
In the last 48h one of my Arista 7050QX-32 rebootet two times. In the same time, there was a packet-storm and some recalculation of RSTP. The Arista is part of a MLAG with another unit, and linked to another Arista 7050QX.
There are NO other devices connected to the unit!
The logs are not very meaningful:
The "next" Arista shows:
--> Ethernet30 is connected to the "rebootet" Arista
--> PortChannel1 is the MLAG-Link of this switch.
Did you ever see something like that?
What do you think - is it a hardware-problem?
Thank you for your hints!
