Port Channel Definition and Standards
Link aggregation is defined by IEEE 802.3ad as a method of grouping multiple physical interfaces into a
single logical interface—a link aggregation group (LAG) or port channel.
A LAG is “a group of links that appear to a MAC client as if they were a single link” according to IEEE
802.3ad. In the Dell Networking OS, a LAG is referred to as a port channel interface.

A port channel provides redundancy by aggregating physical interfaces into one logical interface. If one
physical interface goes down in the port channel, another physical interface carries the traffic.

Port Channel Benefits
A port channel interface provides many benefits, including easy management, link redundancy, and
sharing.
Port channels are transparent to network configurations and can be modified and managed as one
interface. For example, you configure one IP address for the group and that IP address is used for all
routed traffic on the port channel.

With this feature, you can create larger-capacity interfaces by utilizing a group of lower-speed links. For
example, you can build a 30-Gigabit interface by aggregating three 10-Gigabit Ethernet interfaces
together. If one of the five interfaces fails, traffic is redistributed across the four remaining interfaces.

Port Channel Implementation
The system supports static and dynamic port channels.
• Static — Port channels that are statically configured.
• Dynamic — Port channels that are dynamically configured using the link aggregation control protocol
• Dynamic — Port channels that are dynamically configured using the link aggregation control protocol
(LACP). For details, refer to
Up to 128 port- channels with sixteen 10GbE or 40GbE port members per channel are supported.
As soon as you configure a port channel, the system treats it like a physical interface. For example, IEEE
802.1Q tagging is maintained while the physical interface is in the port channel.
