Description: The number of IP packets with headers too small. This is a subset of ipHdrErrors.
What is inHdrTooSmall?
This counter tallies IP packets received with a header too small to be valid, a specific subset of the broader ipHdrErrors count. A nonzero value points to malformed or truncated IP packets reaching the device, which could stem from a misbehaving sender or a packet-crafting attack. An admin seeing inHdrTooSmall increment during a security review would treat it as evidence of malformed traffic worth capturing for further analysis.
