Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: (optional) The total number of LBRs received whose mac_service_data_unit did not match (except for the OpCode) that of the corresponding LBM (20.2.3).

What is dot1agCfmMepLbrBadMsdu?

Counts Loopback Replies (LBRs) received by this MEP whose payload (mac_service_data_unit) didn't match the corresponding Loopback Message, aside from the OpCode. A nonzero count suggests the far-end device or an intermediate device is corrupting or mishandling loopback payloads.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.0.8802.1.1.3.1.6.1.1.28
snmpwalk -v2c -c public <target> IEEE802171-CFM-MIB::dot1agCfmMepLbrBadMsdu

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.0.8802.1.1.3.1.6.1.1.28.1
