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?

Yes the packets will be dropped if Jumbo frames are disabled in the switc

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.
