cmLagHistoryL2CPFD
Module: CM-PERFORMANCE-MIB
OID (symbolic): CM-PERFORMANCE-MIB::cmLagHistoryL2CPFD
OID (numeric): 1.3.6.1.4.1.2544.1.12.5.1.38.1.29
Node type: OBJECT-TYPE
Type: PerfCounter64
Access: read-only
Description: Layer 2 Control Protocol Frames Discarded.
What is cmLagHistoryL2CPFD?
This read-only PerfCounter64 counts Layer 2 Control Protocol Frames Discarded on this link aggregation group as retained in the history bin, the archived counterpart to cmLagStatsL2CPFD. It gives an administrator a historical record of when control-plane frames like LACPDUs or BPDUs were being dropped rather than processed on this LAG. For example, finding a nonzero cmLagHistoryL2CPFD in the bin right before a LAG member unexpectedly went out of sync would explain the loss of aggregation state.
