The primary port replies to flooding and sends protocol data units (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 the properties of the physical interface. The configuration and status of the port channel are also applied to the physical interfaces within the port channel. For example, if the port channel is in Layer 2 mode, you cannot add an IP address or a static MAC address to an interface that is part of that port channel.

If the interface is a member of a port channel, remove it from the first port channel and then add it to the second port channel. Each time you add or remove a channel member from a port channel, Dell Networking OS recalculates the hash algorithm for the port channel. To reassign an interface to a new port channel, use the following commands. 1. Remove the interface from the first port channel. INTERFACE PORT-CHANNEL mode no channel-member interface 2. Change to the second port channel INTERFACE mode. INTERFACE PORT-CHANNEL mode interface port-channel id number Link Aggregation 123
