When more than one interface is added to a Layer 2-port channel, Dell Networking OS selects one of the
active interfaces in the port channel to be the primary port. 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.

Reassigning an Interface to a New Port Channel
An interface can be a member of only one 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
