  • 1.  The processing of Jumbo frame and L2 forwarding

    Hi

    Please let me know about the processing of Jumbo frame.
    I think that the EXOS switch is dropped the jumbo frame, when EXOS switch receive the jumbo frame(larger than 1522 bytes) on condition that disabling is jumbo-frame function.
    (This communication is Layer 2.)

    Is my understanding of this correct?

    What is the condition for Rx-Over to count up?
    I understand that Rx-Over is outputting on show ports rx-error when jumbo frame is received.

    Is Rx-Over outputting even if jumbo frame function is enabled?

    As Karthik said, when Jumbo frame is received in a Jumbo-disabled port, EXOS will drop the packet. However, when we receive a Jumbo frame and it has to egress out of a Jumbo disabled port, EXOS will fragment the packet and send it out.
