Who knows what the USB ports of AP2800 and AP3800 do?

[Rps-Cheers]

I can check the doc from cisco and find the usb of AP2800 can provide power to other devices.

Cisco Aironet 2800 and 3800 Series APs have a USB port that can act as a source of power for some USB devices. The power can be up to 2.5W; if a USB device draws more than 2.5W of power, the USB port shuts down automatically. The port is enabled when the power draw is 2.5W and lower.

https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-8/config-guide/b_cg88/ap_power_and_lan_connections.html#info_ap_usb_port_as_power_source

I want to know if it can only power other devices? Can the device be used as an external storage through the USB port, or upgrade the AP by plugging in the USB?

Thx a lot !

According to the "Getting Started Guide", The USB port does not have any software support at this time. Check out the guide below:

Cisco Aironet 2800 Series Access Points, Getting Started Guide - Cisco

May be for now do not support any usage, Maybe new release code they may use for software upgrade or maybe otehr usage - for now there is no clarity.

Before the 4800 was released, one of the intention was to use the short-lived AIR-BLE-USB-10.

Sorry for the late reply, thank you for your reply.
At present, it seems that this USB interface is not very useful, only waiting for new functions to go online.

[balaji.bandi]

yes correct, if Cisco wants to utilise it later in the future.

[Scott Fella]

The easy answer is "nothing".  It does nothing and probably will never do anything.  You would have to wait and see, but I think after they announce the end of sale, there will be limited features that will be introduced to the ap until it becomes end of support.  You never know, but I think they are focusing on the newer 91x0 access points and not much on the existing x802 ap's.

It sounds reasonable, after all, a new wireless architecture has now been introduced. Maybe AireOS will be phased out, we will wait and see.

[balaji.bandi]

May be IOS XE can get better to use that USB port

[Rps-Cheers]

Yes, but designing this USB on AP2800/3800 seems a bit tasteless.Haha~

So far, I haven't seen how useful it is.

Future communication with Mars most likely!

As others have said, it will probably never have use because we can see wireless smart config all around us in Cisco  competitors. That is way forward.

[Rps-Cheers]

Haha, it may be a pre-set function, if needed, it may be developed at any time

[Scott Fella]

You know they have tested that internally but never officially supported it after the release:) What I remember is that these would most likely be used for external ble beacons.

[Scott Fella]

AireOS is going to be phased out. There already has been statements released on that. If you look, the also released the end of sale for the 3504 and 5520 already. You just have to keep an eye out for when software and hardware support ends.

Thanks for Scott's reply
