Node type: OBJECT-TYPE

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

What is nwDecIVFwdIfCtrLenErrPkts?

nwDecIVFwdIfCtrLenErrPkts is a read-only Counter tracking the total number of DECnet packets discarded because an invalid packet length was contained in the 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 points to packets whose declared length field doesn't match their actual size, often a sign of corruption or a buggy DECnet stack somewhere upstream. For example, a run of length-error discards on this one router port would lead an admin to suspect packet corruption or a faulty DECnet implementation on a peer device through that single port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.2.2.2.1.1.11
snmpwalk -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVFwdIfCtrLenErrPkts

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.3.2.2.2.2.1.1.11.1
snmpget -v2c -c public <target> CTRON-DECIV-ROUTER-MIB::nwDecIVFwdIfCtrLenErrPkts.1
