Description: Indicates the total number of DECnet packets that have been discarded because of an invalid DECnet header, during nwDecIVFwdIfCtrOperationalTime, on the router port for which the entry exists.

What is nwDecIVFwdIfCtrHdrErrPkts?

nwDecIVFwdIfCtrHdrErrPkts is a read-only Counter tracking the total number of DECnet packets discarded because of an invalid or malformed DECnet header, on this one specific router port, identified by the ifIndex value paired with this row, during the relevant OperationalTime measurement window. A rising value flags packets whose DECnet header itself is malformed, a stronger indicator of link-layer corruption or an incompatible DECnet implementation than a simple address mismatch. For example, repeated header-error discards on this one router port would prompt an admin to check cabling or a peer device's DECnet software version through that single port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.2.2.2.1.1.12
snmpwalk -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVFwdIfCtrHdrErrPkts

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.2.2.2.1.1.12.1
snmpget -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVFwdIfCtrHdrErrPkts.1
