    Hi Team,

    I have doubts about the switching capacity of HPE  5950 32QSFP28 Port Switch (JH321A). generally, I do multiply port seed x port count x 2 (Full Duplex). 

    My Answer is 6.4Tbps. But Datasheet shows 3.2Tbps

    Hi! Good catch. IMHO it's an error.

    The Switching Capacity of HPE FlexFabric 5950 32QSFP28 Switch (JH321A) should be 6.4 Tbps as you wrote and not just 3.2 Tbps.

    Not entirely sure about the Forwarding Performance number too (QuickSpecs reports a throughput of "up to 3169 Mpps") but that value depends most on bytes frame used as baseline (considering 64 bytes, the Forwarding Performance should be about "Switching Capacity divided by a 1344 factor" and the result would be higher than actually reported on the linked QuickSpecs).

    How to inform HPE for corrections, because customers use datasheets as a proof document
