wfOsiCircuitClnpInUnknownNlps

Module: Wellfleet-OSI-MIB

OID (symbolic): Wellfleet-OSI-MIB::wfOsiCircuitClnpInUnknownNlps

OID (numeric): 1.3.6.1.4.1.18.3.5.6.3.1.42

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This is the number of Clnp PDUs received on this circuit where the network layer addressed is unknown (Bad NLPID).

What is wfOsiCircuitClnpInUnknownNlps?

Counts CLNP PDUs received on this circuit with an unrecognized network-layer protocol ID (bad NLPID). An admin treats a nonzero count as a sign a neighboring device is sending an unsupported or misconfigured protocol over this circuit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.6.3.1.42
snmpwalk -v2c -c public <target> Wellfleet-OSI-MIB::wfOsiCircuitClnpInUnknownNlps

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.6.3.1.42.1
snmpget -v2c -c public <target> Wellfleet-OSI-MIB::wfOsiCircuitClnpInUnknownNlps.1
