Link Aggregation
Link aggregation is the grouping of physical ports into one logical
higher-capacity link. You may want to trunk ports if, for example, it is cheaper
to use multiple lower-speed links than to under-utilize a high-speed, but more
costly, single-port link.
The Switch supports the link aggregation IEEE802.3ad standard. This standard
describes the Link Aggregation Control Protocol (LACP), which is a protocol
that dynamically creates and manages trunk groups.
When you enable LACP link aggregation on a port, the port can automatically
negotiate with the ports at the remote end of a link to establish trunk groups.
LACP also allows port redundancy, that is, if an operational port fails, then one
of the "standby" ports become operational without user intervention.
Please note that:
LACP only works on full-duplex links.
All ports in the same trunk group must have the same media type, speed,
duplex mode and flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch
to avoid causing network topology loops.
