What is the advantage of enabling LACP or not?
Our backbone is 6 3750 stacked together.
The Access switch are 3750 alone.
Each access switch have 2 giga interfaces to the backbone, this configured with etherchannel.
We got the advices
1. To configure the access switch connected to the backbone with 1000BaseSX with no LACP ->
channel-group 1 mode on
2. To configure the one conneted to the backbone with 1000BaseLX with LACP ->
channel-group 1 mode passive/active
Is that true? if yes why?
Many thanks for your help.
