Link Aggregation Control Protocol
Link Aggregation Control Protocol (LACP) is an IEEE 802.3ad standard for grouping several
physical ports into one logical port (known as a dynamic trunk group or Link Aggregation group)
with any device that supports the standard. Please refer to IEEE 802.3ad-2002 for a full description
of the standard.
The 802.3ad standard allows standard Ethernet links to form a single Layer 2 link using the Link
Aggregation Control Protocol (LACP). Link aggregation is a method of grouping physical link
segments of the same media type and speed in full duplex, and treating them as if they were part of
a single, logical link segment. If a link in a LACP trunk group fails, traffic is reassigned
dynamically to the remaining link(s) of the dynamic trunk group.
Note – LACP implementation in the Blade OS does not support the Churn machine, an option used
to detect if the port is operable within a bounded time period between the actor
and the partner. Only the Marker Responder is implemented, and there is no marker protocol
generator.
