INTERFACE PORT-CHANNEL mode
channel-member interface
The interface variable is the physical interface type and slot/port information.
2. Double check that the interface was added to the port channel.
INTERFACE PORT-CHANNEL mode
show config
To view the port channel’s status and channel members in a tabular format, use the show interfaces port-channel
brief command in EXEC Privilege mode, as shown in the following example.
DellEMC#show int port brief
LAG Mode Status Uptime Ports
1 L2L3 up 00:06:03 Te 1/1/1/1 (Up) *
Te 1/1/1/2 (Up)
2 L2L3 up 00:06:03 Te 1/1/1/3 (Up) *
Te 1/1/1/4 (Up)
Te 1/1/2/1 (Up)
Te 1/1/2/2 (Up)

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 EMC 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 1/6/1 is part of port channel 5, which is in Layer 2
mode, and an error message appeared when an IP address was configured.
