Hello,
I have noticed that my Cisco switch drops IPv4 packets if the version or checksum field is incorrect.
The same happens for IPv6 packets where the version field is incorrect.
I have not tested any other header fields, but there are probably more fields that are checked?
Is there a way to disable this? I cannot find anything about this in the manuals.
I already have disabled all features except for lacp and sshserver.
I want to disable this feature because network data that travels across the Cisco is encrypted from the Ethernet header onward, which means that the complete IPv4/IPv6 header is scrambled data.
Hardware/software version:
Cisco Nexus N9K-C93180YC-EX
NX-OS 9.3(3)
