4 Link Aggregation (LA)
Link Aggregation (LA) is a method of combining multiple parallel physical connections into a
single logical connection(trunk), thus allowing increased bandwidth for a particular network path
beyond what a single connection could sustain. By taking multiple LAN connections and treating
them as a unified, aggregated link, practical benefits in many applications can be achieved. For
example, link aggregation provides redundancy in case one of the links fails. Link Aggregation
also provides load balancing so that processing and communication activity is distributed across
several links in a trunk ensuring that no single link is overwhelmed.
Other terms often used to describe this Link Aggregation method include port trunking, link
bundling, bonding, or teaming. These umbrella terms encompass industry standards such as
IEEE 802.1ax Link Aggregation Control Protocol (LACP) for wired Ethernet, or the previous IEEE
802.3ad, as well as various proprietary solutions. In this manual we will also refer to a particular
group of aggregated links as a Port Channel.
Supermicro switches support both static link aggregation and dynamic link aggregation using
IEEE 802.3ad and LACP. Up to 24 Port Channels can be configured on an individual switch and
each Port Channel can contain up to 8 members.
Configure port channel or link aggregation as follows:
Enable LA Status
Create a port channel
Associate the port channel you have created with the required ports
Configure any port-channel-specific parameters
4.1 Enabling LA Status
LA status can be enabled in Layer2 Mgmt
