What is inHdrBadVersion?
This counter tallies IP packets received with incorrect IP version information in the header, a specific subset of the broader ipHdrErrors count. A rising value suggests either a non-IPv4 protocol being mistakenly sent to the device or corrupted packets misrepresenting their own version field. An admin seeing inHdrBadVersion increment on a network that should be purely IPv4 would investigate what device on the segment is generating non-conforming traffic.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.426.1.12.2 snmpwalk -v2c -c public <target> COMPEX-IN3000::inHdrBadVersion
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.426.1.12.2.1 snmpget -v2c -c public <target> COMPEX-IN3000::inHdrBadVersion.1
