Member ports of a LAG are added and programmed into the hardware in a predictable order based on the
port ID, instead of in the order in which the ports come up. With this implementation, load balancing yields
predictable results across device reloads.
A physical interface can belong to only one port channel at a time.
Each port channel must contain interfaces of the same interface type/speed.
Port channels can contain a mix of 1G/10G/40G. The interface speed that the port channel uses is
determined by the first port channel member that is physically up. Dell Networking OS disables the interfaces
that do not match the interface speed that the first channel member sets. That first interface may be either
the interface that is physically brought up first or was physically operating when interfaces were added to the
port channel. For example, if the first operational interface in the port channel is a Tengigabit Ethernet
interface, all interfaces at 10000 Mbps are kept up, and all other interfaces that are not set to 10G speed or
auto negotiate are disabled.
Dell Networking OS brings up the interfaces that are set to auto negotiate so that their speed is identical to
the speed of the first channel member in the port channel.
Interfaces in Port Channels
When interfaces are added to a port channel, the interfaces must share a common speed. When interfaces
have a configured speed different from the port channel speed, the software disables those interfaces.
The common speed is determined when the port channel is first enabled. Then, the software checks the first
interface listed in the port channel configuration. If you enabled that interface, its speed configuration
becomes the common speed of the port channel. If the other interfaces configured in that port channel are
configured with a different speed, Dell Networking OS disables them.

Configuration Tasks for Port Channel Interfaces
To configure a port channel (LAG), use the commands similar to those found in physical interfaces. By default,
no port channels are configured in the startup configuration.
These are the mandatory and optional configuration tasks:
•
(mandatory)
•
Adding a Physical Interface to a Port Channel
•
Reassigning an Interface to a New Port Channel
(optional)
