After you enable the port channel, you can place it in Layer 2 or Layer 3 mode. To place the port channel in Layer 2 mode or
configure an IP address to place the port channel in Layer 3 mode, use the switchport command.
You can configure a port channel as you would a physical interface by enabling or configuring protocols or assigning access
control lists.
Adding a Physical Interface to a Port Channel
The physical interfaces in a port channel can be on any line card in the chassis, but must be the same physical type.
NOTE: Port channels can contain a mix of Ethernet interfaces, but Dell EMC Networking OS disables the interfaces that
are not the same speed of the first channel member in the port channel (refer to 10/100/1000 Mbps Interfaces in Port
Channels).
You can add any physical interface to a port channel if the interface configuration is minimal. You can configure only the
following commands on an interface if it is a member of a port channel:
● description
● shutdown/no shutdown
● mtu
NOTE: A logical port channel interface cannot have flow control. Flow control can only be present on the physical
interfaces if they are part of a port channel.
NOTE: The system supports jumbo frames by default (the default maximum transmission unit (MTU) is 1554 bytes). To
configure the MTU, use the mtu command from INTERFACE mode.
To view the interface’s configuration, enter INTERFACE mode for that interface and use the show config command or from
EXEC Privilege mode, use the show running-config interface interface command.
When an interface is added to a port channel, Dell EMC Networking OS recalculates the hash algorithm.
To add a physical interface to a port, use the following commands.
1. Add the interface to a port channel.
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 Gi 1/6 (Up) *
Gi 1/12 (Up)
2 L2L3 up 00:06:03 Gi 1/7 (Up) *
Gi 1/8 (Up)
Gi 1/13 (Up)
Gi 1/14 (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.
DellEMC>show interface port-channel 20
Port-channel 20 is up, line protocol is up
Hardware address is 00:01:e8:01:46:fa
Internet address is 1.1.120.1/24
MTU 1554 bytes, IP MTU 1500 bytes
