## Variable definitions

The following table describes the fields of LACP tab.

Field | Description
--- | ---
LACPDUsRX | Denotes the number of valid LACPDUs received on this Aggregation Port. This value is read-only.
MarkerPDUsRX | Signifies the number of valid Marker PDUs received on this Aggregation Port. This value is read-only.
MarkerResponsePDUsRX | The number of valid Marker Response PDUs received on this Aggregation Port. This value is read-only.
UnknownRX | Indicates the number of frames received that can Carry the Slow Protocols Ethernet Type value (43B.4), but contain an unknown PDU. Are addressed to the Slow Protocols group MAC Address (43B.3), but do not carry the Slow Protocols Ethernet Type. This value is read-only.
IllegalRX | Denotes 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.
LACPDUsTX | Signifies the number of LACPDUs that are transmitted on this Aggregation Port. This value is read-only.
MarkerPDUsTX | Displays the number of Marker PDUs transmitted on this Aggregation Port. This value is read-only.
MarkerResponsePDUsTX | Indicates the number of Marker Response PDUs that are transmitted on this Aggregation Port. This value is read-only.
