Dell S4048-ON, Configuration Manual

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 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. 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 configured.
Dell(conf-if-portch)#show config
!
interface Port-channel 5
no ip address
switchport
channel-member TenGigabitEthernet 1/6
Dell(conf-if-portch)#int Te 1/6
Dell(conf-if)#ip address 10.56.4.4 /24
% Error: Port is part of a LAG Te 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 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.
