Issue

Transmitted packets appear to be larger than the configured MTU in a packet capture.

  • How can a packet trace show the packets transmitted that are larger than the MTU size?
  • How can a packet trace show the packets transmitted that are larger then a Jumbo frame (~9000 bytes)?

If packets that are larger than MTU are received, see KB on LRO/RSC: The packets received appear to be larger than the configured MTU in a packet capture
