hpnicfDot3OamUnsupportedCodesTx

Module: HPN-ICF-EFM-COMMON-MIB

OID (symbolic): HPN-ICF-EFM-COMMON-MIB::hpnicfDot3OamUnsupportedCodesTx

OID (numeric): 1.3.6.1.4.1.11.2.14.11.15.2.42.3.1.4.1.15

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the number of OAMPDUs transmitted on this interface with an unsupported op-code.

An unsupported opcode OAMPDU is indicated by a valid frame with (1) destination MAC address equal to that of the reserved MAC address for Slow Protocols (See 43B of [802.3ah]), (2) a lengthOrType field equal to the reserved type for Slow Protocols, (3) a Slow Protocols subtype equal to that of the subtype reserved for OAM, and (4) an OAMPDU code equals the opcode for a function that is not supported by the device.

Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.

What is hpnicfDot3OamUnsupportedCodesTx?

This counts OAMPDUs transmitted on this interface using an opcode this device doesn't support. A nonzero, growing value here would be unusual and worth investigating, since it implies the local OAM stack is generating requests for functions it doesn't actually implement.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.15.2.42.3.1.4.1.15
snmpwalk -v2c -c public <target> HPN-ICF-EFM-COMMON-MIB::hpnicfDot3OamUnsupportedCodesTx

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.14.11.15.2.42.3.1.4.1.15.1
snmpget -v2c -c public <target> HPN-ICF-EFM-COMMON-MIB::hpnicfDot3OamUnsupportedCodesTx.1
