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. As the following
example illustrates, interface 10-GigabitEthernet 1/6 is part of port channel 5, which is in Layer 2 mode,
and an error message appeared when an IP address was configured.

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, you
must 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 these commands in the following sequence in the
INTERFACE mode of a port channel:
Step Command Syntax Command Mode Purpose
1 no channel-member interface INTERFACE
PORT-CHANNEL
Remove the interface from the first port
channel.
2
interface port-channel id number INTERFACE
PORT-CHANNEL
Change to the second port channel
INTERFACE mode.
3
channel-member interface INTERFACE
PORT-CHANNEL
Add the interface to the second port channel.
