Link aggregation group optimization
Examples disclosed herein relate to a method comprising detecting a plurality of port sets between a first networking device with a first plurality of ports and a second networking device with a second plurality of ports, wherein each port set includes a first and second port of the first device having a same available interface rate. The method may comprise determining an interface rate and an operational state for each port set that is available to form a Link Aggregation Group and determining each grouping of port sets between the first and second device, wherein each grouping has at least one port set and each port set in the grouping has a same interface rate. The method may comprise calculating the interface rate for each grouping, determining a group with a highest interface rate from among the groupings and programing ports of the group into the LAG distribution.
