Link Aggregation 67
4.4 Link Aggregation
Link aggregation is a function that combines multiple ports into a single logical link. A set of ports that comprise a logical
link are called an aggregation group.
Link aggregation provides:
• Increased bandwidth
By grouping multiple physical ports into a single logical link (an aggregation group), network traffic (data sent and
received) will be balanced across the physical ports, thereby providing increased bandwidth.
• Redundancy
Multiplexing ports allows uninterrupted network operations should one of the multiple links fail. Since the link status
of the logical aggregation groups remains unchanged, there are no fluctuations in network traffic, the effect of a fault
having been minimized.
Up to 10 ports can be used to create a single link aggregation group using link aggregation. Up to 10 aggregation groups
can be created.
