PoE Cisco Switch

I need to perform a quick test. I have a Cisco Meraki (MR12) Access Point and need to confirm whether or not the device maintains its configuration once it loses connectivity to the Internet.

The device currently connects to a port on my closet PoE switch. What I want to know is if I shut the respective port down (ie preventing it to connect to the Internet) will the PoE port continue to send power to the device?

The AP will retain it's configuration even when the cloud is unavailable. You will not be able to make changes or obtain any updates, but it should still function. If you turn off the port which leads towards the internet the AP will stay up. If you shut down the port the AP is connected to you will also power down the AP, unless you have a separate power supply for the AP.

If you shutdown the port, the device should not be getting power.

you can also just disable POE on the port with
ROUTER (config)#Interface GigabitEthernet0/1
ROUTER (config-if)# power inline never 

Open in new window

And enable it with
ROUTER (config)#Interface GigabitEthernet0/1
ROUTER (config-if)# power inline auto

Open in new window

I don't want to disable the power. I want to keep the AP powered on (via the PoE switch/port) but disonncect it from the Internet.

Then you are limited to a few methods.
Disconnect the switch's uplink.
Put it on a vlan that isn't routable or doesn't exist outside of the switch.
Apply an ACL to the vlan/router to deny all traffic sourced from the AP itself.
Use a power injector without a connection to a switch to provide power only to the AP.

If you still need clients to connect to the AP and access the network you should go with the ACL method.

Yep rauenpc is correct.  You should put the AP in a VLAN that goes nowhere - that's the easiest way.  If you shutdown the port the PoE to that port will also be turned off.
