4 Link Aggregation
`
The Link Aggregation feature connects two or more physical links between two network devices without
forming loops. Link aggregation can be used between switches, servers and routers.
Link aggregation provides the following advantages:
Increased bandwidth – User can connect up to eight physical links between devices to increase the link
bandwidth. When 25 Gbps links are aggregated, users can get an aggregated link with up to 200 Gbps
bandwidth. When ports are set to 10Gig speed, users can aggregate eight 10Gig ports to get an aggregated
uplink with up to 80 Gbps.
Incremental bandwidth – Users can start aggregation with a fewer number of ports and then increase the
number of ports in aggregation (up to eight) incrementally based on the bandwidth requirements.
Redundancy - When one of the physical links fails, traffic will be distributed over the other remaining links
in the aggregation.
