Hi All

Is it possible to configure pagp or lacp channels using more than one switch ie with 2 switches connected together (not in a stack) and using a port on each create a etherchannel? I have a requirement to diversify links but would like to channel the links up to get better bandwidth utilization.

HI Nhon,


If your requirement is this


sw1 (port 1)---(port 1) sw2

sw1 (port 2)---(port 2) sw2


it is very much possible and this is the way etherchannel muct be use.


But if your requirement is


sw1 (port 1)----(port 1) sw3

sw2 (port 1)----(port 2) sw3


this is not possible as of now as etherchannel cannot be split between 2 switches.
