mode lacp max active-linknumber 2 trunkport gig 0/0/1 to 0/0/3

This configuration command is used to enable Link Aggregation Control Protocol (LACP) on a switch and create a trunk port with a maximum of two active links between Gigabit Ethernet ports 0/0/1 to 0/0/3. LACP is a protocol that allows multiple physical links between two devices to be combined into a single logical link, increasing overall bandwidth and providing redundancy in case of link failure. The "max active-linknumber 2" part of the command specifies that only two of the available links will be active at any given time.
