Applies to

  • ONTAP 9
  • TSO (TCP Segmentation Offload)

Answer

  • The TSO feature of NIC divides packets after packet capture.
  • In other words, at the time of packet capture, the packets have not been segmented by TSO yet.
  • Therefore, network packets with a length exceeding 1500 can be observed.
  • This is the expected behavior and does not affect the client.
