pagp/lacp over multiple switches

Answered Question
Sep 24th, 2007

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.
