Description (partial)

Packet drops occur on a linecard when the LtlFpoeMemoryConsistency online diag test is enabled on the Supervisor. Packets are dropped along a vlan or vrf path where the packets are being lost across the fabric.
The problem occurs at room temp when traffic is running across the fabric between ports, while the LtlFpoeMemoryConsistency test is enabled. The packets will drop regardless of whether the traffic is layer 2 or 3.
