1552 without WLC

endpoint — Sun, 04 Jul 2021 06:40:57 GMT

is it possible to setup and use 1552 AP as a standalone AP, without WLC to act as a bridge between two locations and possible to serve the clients?

With 1142 (indoor) i can setup autonomouse mode, access 1142 AP over the http ad configure it without using WLC.

Can the same be done with 1552 without having to use WLC? Was able to setup static IP on 1552 but dont see the option to configure it further.

Thanks

I don't think so. I think there is an autonomous code for survey purposes but if you intend using it for production you need a WLC.

I believe you are right, i would need WLC.

I got authonomous code installed, could you share how to set it up for survey purposes?

It would be configured like any other autonomous access point. I don't believe at there is a config guide for the MESH AP, but you can reference the code release configuration guide which is general.

which code you installed? c1520-k9w7-tar.152-2.JB.tar ?

Was it full autonomous mode, or just site survey?

If you want to use it as an autonomous AP I guess you could use the code as it is fully functional and supported. But then you wouldn't have a mesh ap, just a FAT AP:)

Support for AP1550, AP3500E, AP3500I, AP3600E, and AP3600I,

This release provides complete software functionality to AP1550, AP3500E, AP3500I, AP3600E, and AP3600I series access points.

Thanks Scott,

I just today saw one partner providing the AP with the autonomous image to one of the customer. No controller ordered. So I was not sure if they were intending to use it as autonomous on the long term or the customer has already a controller.

(If a customer has a controller then it does not matter to mention the image but the image was clearly mentioned separately in the order).

Not sure, but maybe it can be used if you want an outdoor, not MESH AP.

Amjad,

That is interesting that someone would use that expensive AP as autonomous, when you can just throw in a 2504 and use the full feature of the 1550. It's an interesting idea, but very expensive:)

The reason why (I think) is they need to install it outside in very tough weather conditions. besides they are intending to cover relatively large area. Indooer APs won't work and buying an additional controller is beyond the budget. maybe that's why.

Hi guys. I'm at customer site. We have one AP1552 in mesh mode. We want to reinstall this software and use it as autonomous. Anyway, the problem that PC cant reach AP, AP cant reach PC AP can get IP address with DHCP or use static. But PING doesn't work.

Any specific upgrade procedure is needed for these mesh AP's 1552?

Well if you have a power injector, that would be the best way to access the mesh AP. I would then do the debug capwap console cli and then the archive download-sw command. If the mesh is up and joined to the RAP, you might also have to issue this command so that the AP doesn't reload: debug capwap client no-reload

Thanks,

Scott

Scott,

There is nothing configured. I just have brand new Cisco AP1552 with MESH software image and my laptop. AP gets IP address, but can't reach anything anyway.

AP#sh ip int br

Interface IP-Address OK? Method Status Protocol

BVI1 192.168.32.126 YES DHCP up up

Dot11Radio0 unassigned NO unset up up

Dot11Radio1 unassigned NO unset up up

GigabitEthernet0 unassigned NO unset up up

GigabitEthernet1 unassigned NO unset up down

GigabitEthernet2 unassigned NO unset up down

GigabitEthernet3 unassigned NO unset up down

Also I can see arp table:

AP#sh arp

Protocol Address Age (min) Hardware Addr Type Interface

Internet 192.168.32.102 7 001e.8c4f.c8a6 ARPA BVI1

Internet 192.168.32.254 2 001b.66a4.c340 ARPA BVI1

I thought it simple upgrade process like with other APs. Magic?

OK. I tried to connect this AP to the vWLC. I can see this ouput on AP console:

vWLC has bad certificate?

The outdoor mesh isn't supported on the vWLC.

At this page https://supportforums.cisco.com/docs/DOC-26765 I found this :

Features Not Supported on vWLC

Outdoor mesh access points (Outdoor AP with FlexConnect mode will work)

So I thought, AP would be able to download FlexConnect image!

But anyway. AP/PC/vWLC is on the same subnet. But it is impossible to ping AP. Other devices are not pingable from AP!

How this is possible? Is it normal for mesh APs?

Maybe it is impossible to use any commands even ping in MESH mode without active WLC connection?

Guys!

I got some really valuable information from one guy. His name is Sam. Sam says:

"Autonomous code is indeed supported on the 1552 platform. Getting the image onto the AP is somewhat tricky. Since there is no 'mode' button to hold down to perform an image recovery with, you have two options:

1) open up the unit and use the serial console to perform the image upgrade from ROMMON (difficult, but can be done without a controller) or

2) join the AP to a controller in mesh mode then use the 'config ap tftp-downgrade' command at the WLC CLI (easy, but requires a controller).

More details on this method can be found at:

http://www.cisco.com/en/US/docs/wireless/controller/3.2/configuration/guide/c32lwap.html

(config guide is old, but commands are the same in new versions of code)"

Hope this helps for everyone!

Hello,

Please have a look at 'Getting Started Guide: Cisco Aironet 1550 Series Outdoor Mesh Access Points'

I think this should clarify your situation.
