3935i LACP with same switch possible ?

3935i LACP with same switch possible ?

We are using 3935i APs

They are connected to only one port : I saw the LOW mode in the log

We would like to use it with performance: we have to use TWO ethernet ports

Is it possible with only one POE switch X440-48P

Thanks

Pascal,

Based on my lab, it is working fine with 3935i as below information.
I will ask the article creator to change details.
And please notice that I used fallback feature of LACP to ensure connection when AP is not set to use LACP so that you can change setting of the AP after all.

Actually, I tested this both with AP3825i and AP3935i few month ago.
It worked okay with AP3935i while AP3825i didn't as the above article.
AP3935i should be removed from the article I think.
I will check again and let you know later.

The switch could support 802.3at so you should be able to get full power from one port.
A think you run into the same issue as I did with another switch model - please take a look...

And If the customer have only one switch ...
Can we use an injector on the second port ? (strange ... but how can we have the Full power mode with one switch) ?
