ipInHdrErrors
Module: IP-MIB
OID (symbolic): IP-MIB::ipInHdrErrors
OID (numeric): 1.3.6.1.2.1.4.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of input datagrams discarded due to errors in their IPv4 headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IPv4 options, etc.
This object has been deprecated as a new IP version-neutral table has been added. It is loosely replaced by ipSystemStatsInHdrErrors.
What is ipInHdrErrors?
This deprecated counter tallies the total number of IPv4 packets that were discarded due to errors in their IP headers, including bad checksums, version mismatches, malformed options, or exceeded time-to-live values. It provides a broad measure of packet-level data corruption or misconfiguration affecting incoming traffic at the IP layer. Network troubleshooters inspect this counter to diagnose large-scale packet corruption, but should prefer the newer ipSystemStatsInHdrErrors object for version-neutral reporting.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.4.4 snmpwalk -v2c -c public <target> IP-MIB::ipInHdrErrors
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.4.4.1 snmpget -v2c -c public <target> IP-MIB::ipInHdrErrors.1
