cisco ios // setup lacp on catalyst switches

basics | defaults | fw | init | lacp | passwords | setup | ssh

we want two times 3-port aggregates for linking GNU/Linux servers

int range gi0/9 - 11
    channel-protocol lacp
    channel-group 1 mode passive

int range gi0/25 - 27
    channel-protocol lacp
    channel-group 2 mode passive

choose the vlan on which this is all going to work

int range po1 - 2
    switchport mode access
    switchport access vlan 400

check

show interfaces status
show etherchannel 1 summary
show etherchannel 2 summary

more details on LACPDU rate

show lacp internal

more commands

show interfaces gi 0/9 etherchannel
show interfaces gi 0/25 etherchannel
show etherchannel 1 detail
show etherchannel 2 detail
show etherchannel load-balance
show etherchannel 1 port-channel
show etherchannel 2 port-channel

ready to go

you’re good to proceed on the server side
