bycomparingoperationalkeys.Aggregatorportsallow onlyunderlyingportswithkeysmatching
theirstojointheirLAG.
LACPusesasystempriorityvaluetobuildaLAGID,whichdeterminesaggregationprecedence.
Iftherearetwopartnerdevicescompetingforthesameaggregator,LACPcomparestheLAGIDs
foreach
groupingofports.TheLAGwiththelowerLAGIDisgivenprecedenceandwillbe
allowedtousetheaggregator.
Thereareafewcasesinwhichportswillnotaggregate:
•Anunderlyingphysicalportisattachedtoanotherportonthissameswitch(loopback).
•Thereisnoavailableaggregatorfor
twoormoreportswiththesameLAGID.Thiscan
happeniftherearesimplynoavailableaggregators,orifnoneoftheaggregatorshavea
matchingadminkeyandsystempriority.

TheLACPimplementationon
theMatrixSeriesdevicewillallowuptoamaximumoffourports

Commands
Note: Only one LACP system priority can be set on a Matrix Series device, using either the set lacp
asyspri command (“set lacp asyspri” on page 4-60), or the set port lacp command (“set port lacp”
on page 4-66).
Note: To aggregate, underlying physical ports must be running in full duplex mode and must be of
the same operating speed.
