(running in low power mode)

[Josreny]

Hi, I have an AP  Cisco Meraki connected to SW Catalyst 3560G series PoE 24, the state of AP is (running in low power mode) but I tried to configure the port where is connected the AP with the comand "power inline max 30000" and "lldp run" and "lldp transmit" but the answer of putty is "Invalid input detected", please help because I dont know if the Switch is bad or I'am doing something wrown...

To which line of config did it say "invalid input"?

[Josreny]

that says in the line of configuration of interface:   (Switch(config-if)#)

As @BrechtSchamp  says, the 3560G does not support 30W of output, so that is why the command is being rejected.  You would have needed a Cisco 3560-X.

Cisco stopped selling the Cisco 3560G back in 2013 - so your switch is at least 6 years old.

You could get a nice new shiny Cisco Meraki switch to bring your infrastructure up to date ...

3560G only supports 802.3af (PoE up to 15W). You're likely using MR42 or up that need 802.3at (PoE+ up to 30W) for full  functionality.
