Link Aggregation

5 Link Aggregation
There is link aggregation when there are at least two link cables between two
switches and when these link cables are combined to one logical link. The
complete bandwidth of link cables is available for data transmission. The load
distribution of the link lines is effected dynamically. All link lines together are
referred to as the „trunk".
Fig. 32: Example of link aggregation
Any combination of twisted pair and LWL cables can be used as the connec-
tion lines of a trunk. It is only necessary that for all the connections, the trans-
mission speed and the duplex settings of the related ports are the same.
You can use link aggregation to combine into a trunk up to eight (optimally
up to four) connection lines between switches. These links increase the data
rate, and, in the event that a link should fail, the remaining links take over the
entire data traffic.
A maximum of 4 trunks can exit a switch.
