Link Aggregation

2 Link Aggregation
The LACP (Link Aggregation Control Protocol based on IEEE 802.3ad) is a
network protocol for dynamically bundling physical network connections. The
added bandwidth of all connection lines is available for data transmission. In
the case of a connection breaking down, the remaining connections take
over the entire data transmission (redundancy). The load distribution
between the connection lines is performed automatically.
You configure a link aggregation by combining at least 2 existing parallel
redundant connection lines (known as a trunk) between two devices into one
logical connection. You can use link aggregation to combine up to 8
(optimally up to 4) connection lines between devices into a trunk.
Any combination of twisted pair and F/O cables can be used as the
connection lines of a trunk. Configure the connections so that the data rates
and the duplex settings of the related ports are matching.
The maximum that can exit a device are
– 2 trunks for rail devices with 4 ports,
– 4 trunks for rail and MICE devices with 8-10 ports,
– 7 trunks for all other devices.
