The total length is the length of the whole packet. This is a 16 bit field, so it can have numbers between 0 and 65535. These numbers represent bytes directly. atlas fusd

Yes, but i still do not understand why in the pcap captured from ACI I see "IPv4 total length exceeds packet length"

I now a little about ACI but I know it work for Spine and Leaf and NSK device, check the CoPP of NSK if it allow this size or not.
