LACP
Link Aggregation Control Protocol. LACP allows bundling of several physical ports to form
a single logical channel providing enhanced performance and redundancy. The
aggregated channel is viewed as a single link to each switch. The spanning tree views the
channel as one interface and not as multiple interfaces. When there is a failure in one
physical port, the other ports stay up and there is no disruption. LACP does not
interoperate with devices that use Port Aggregation Protocol (PAgP).
For an more information see “Link Aggregation Control Protocol (LACP)” on page 20.3 .

Layer 3 switch
A Layer 3 switch is an optimized combination of routing software and specialized
hardware. The software uses traditional methods (static routing commands, and routing
protocols) to build up a table of the best routes to network destinations, and then writes
them into a set of registers in the specialized forwarding hardware. The hardware then
forwards packets, based on their Layer 3 address content, at very high data rates, using the
values that are written into the registers.
LED
Light Emitting Diode (LED). An LED is a semiconductor that emits light by converting
electrical energy. Power lights on switches and status lights on switch ports are LEDs. You
can save power used by switch LEDs with the
ecofriendly led command on page 8.13 .
For more information and configuration examples see the section “Save Power With the
Eco-Friendly Feature” on page 1.32 . For command information and examples see the
ecofriendly led command on page 8.13 . See also the LPI glossary entry.
