ICMP-IPv4 total length exceeds packet length

[MariniSimone1975]

I have a problem with +500byte ICMP packet, I am pinging from end-points residing outside ACI arriving in two different  L3OUT.

The ping suceed but in the pcap caputer from the APIC I see the following

Total Length: 528
 - [Expert Info (Error/Protocol): IPv4 total length exceeds packet length (182 bytes)]

1 0.000000000 172.25.164.38 172.25.38.1 ICMP 246 Echo (ping) request id=0x003f, seq=51002/15047, ttl=126 (no response found!)

2 0.000091094 172.25.164.38 172.25.38.1 ICMP 246 Echo (ping) request id=0x003f, seq=51002/15047, ttl=123 (reply in 3)

3 0.000709328 172.25.38.1 172.25.164.38 ICMP 246 Echo (ping) reply id=0x003f, seq=51002/15047, ttl=255 (request in 2)

4 0.003341978 172.25.38.1 172.25.164.38 ICMP 246 Echo (ping) reply id=0x003f, seq=51002/15047, ttl=252

Can someone help me to undestand what is the reason for the this error and how to solve it?

Thanks in advance

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.
