Nous constatons une saturation sur le B, nous allons ajouter de la capacité en urgence. Nous ne constatons plus de loss depuis les isolations.

We see saturation on B, we will add capacity urgently. We don't see more loss since isolation.

We think the bug is 181627:
On the DCS-7500R and DCS-7280R series, packets buffered in external DRAM may intermittently experience corruption which can cause those packets to be dropped.

Awaiting Arista confirmation.
