By default, LACP PDUs received on an interface where LACP is not configured are discarded. For scenarios in which the interface requires LACP PDU packet forwarding, you can configure the device to forward the LACP PDU on the VLAN on which it is received using the lacp-pdu-forward enable command in the interface configuration mode or port channel configuration mode.
Since the destination address of the PDU is a multicast MAC, the frame will be flooded on the VLAN. If the VLAN on which the LACP PDU is received is a regular VLAN, the PDU will be flooded on the VLAN. If the VLAN on which the PDU is received is a service delimiter for a bridge domain, the LACP PDU is flooded on the bridge domain accordingly.
LACP PDU forwarding is supported only on physical interfaces and static port channel interfaces. LACP PDUs cannot be forwarded if they are received on a LACP based dynamic port channel. LACP PDU forwarding enabled on a static port channel applies to all the member ports. If LACP is enabled on a port, it overrides the LACP PDU forwarding configuration and the PDUs are trapped in the CPU.
