The following example shows the port channel’s mode (L2 for Layer 2 and L3 for Layer 3 and L2L3 for a Layer 2-port channel assigned to a
routed VLAN), the status, and the number of interfaces belonging to the port channel.

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 ooding 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 conguration 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. In the following example, interface TenGigabitEthernet 1/6 is part of port channel 5, which is in Layer 2 mode, and an error
message appeared when an IP address was congured.
Dell(conf-if-portch)#show config
!
interface Port-channel 5
no ip address
switchport
channel-member GigabitEthernet 1/6
Dell(conf-if-portch)#int Gi 1/6
Dell(conf-if)#ip address 10.56.4.4 /24
% Error: Port is part of a LAG Gi 1/6.
Dell(conf-if)#
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 rst 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 rst port channel.
