Mokerlink switch results:

• Saturated 2.5Gbe adapters I have (some of them can’t do 2.5Gbe as they are USB3, but they were all doing at least 1.6Gbps bidirectional). Ran this test for an hour with no issues. Transferred nearly 2.5TB of data across the switch during this time.
• Increased MTU on interfaces to 12000 and increased ping packet size until it failed. Failed at 1504 bytes, so no jumbo frames at all
• Added VLAN interface and ping’d across that, worked fine, even at full MTU, so it seems to be carrying VLAN tags correctly from what I can tell
• Did not try QinQ frames
