acDot3adAggPortStatsIllegalRx
Module: AC-LAG-MIB
OID (symbolic): AC-LAG-MIB::acDot3adAggPortStatsIllegalRx
OID (numeric): 1.3.6.1.4.1.2785.2.3.8.1.2.2.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of frames received that carry the Slow Protocols Ethernet Type value (43B.4), but contain a badly formed PDU or an illegal value of Protocol Subtype (43B.4). This value is read-only.
What is acDot3adAggPortStatsIllegalRx?
This counter increments when malformed LACP or marker PDUs arrive, signaling corrupted packets or protocol violations on the aggregation port. Engineers investigating LAG instability watch this for signs of link-layer corruption or faulty hardware. Example: rapid increases (e.g., 100 illegal frames in 10 seconds) suggest a hardware fault or packet corruption on the wire.
