The primary port replies to flooding and sends protocol PDUs.An asterisk in the show interfaces port-channel brief command indicates the primary port.As soon as a physical interface is added to a port channel, the properties of the port channel determine theproperties of the physical interface. The configuration and status of the port channel are also applied to thephysical interfaces within the port channel. For example, if the port channel is in Layer 2 mode, you cannotadd an IP address or a static MAC address to an interface that is part of that port channel.As the followingexample illustrates, interface GigabitEthernet 1/6 is part of port channel 5, which is in Layer 2 mode, andan error message appeared when an IP address was configured.FTOS(conf-if-portch)#show config!interface Port-channel 5no ip addressswitchportchannel-member GigabitEthernet 1/6FTOS(conf-if-portch)#int gi 1/6FTOS(conf-if)#ip address 10.56.4.4 /24% Error: Port is part of a LAG Gi 1/6.FTOS(conf-if)#
