Configures the device to forward LACP PDUs received on an interface where LACP is not configured, to the VLAN on which the LACP PDUs are received.
LACP PDUs received on an interface where LACP is not configured are discarded.
Interface subtype configuration mode
LACP PDUs are forwarded only when they are received on a physical interface or static port channel interface. 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.
When LACP is enabled on a port, it overrides LACP PDU forwarding configuration and the PDUs are trapped to CPU.
Enabling and disabling of BPDU drop on a bridge domain does not impact LACP PDU forwarding.
Caution
When using this command on a physical port or a static port-channel, consider the need and the use case. Using this command will flood PDUs and may affect other existing port-channels in the network.lacp-pdu-forward cannot be enabled on any interface that is not a physical port or a static port-channel. When attempted, the message %Error: Cannot enable LACP PDU Forwarding on a non-static Port-Channel. is displayed.
Use the no form of the command to disable LACP PDU forwarding.
The following example configures LACP PDU forwarding on a physical interface.
device# configure terminal device(config)# interface ethernet 4/1 device(conf-if-eth-4/1)# lacp-pdu-forward enable
The following example configures LACP PDU forwarding on a static port channel interface.
device# configure terminal device(config)# interface port-channel 10 device(config-Port-channel-10)# lacp-pdu-forward enable
