ap redeploy controller-less doesn't work for non Unified APs

Hi all,

 

Starting a topic to warn others of an undocumented limitation with the ap redeploy controller-less command which was introducted in AOS 6.5.2.0.

 

The CLI Guide states: 

 

ap redeploy controller-less

ap redeploy controller-less

all                   

ap-group <ap-group>

ap-name <ap-name>

ip-addr <ip-addr>

ip6-addr <ip6-addr>

wired-mac <wired-mac>

Description

This command sets the AP preference role to controller-less, allowing the AP to bypass controller discovery and immediately initiate Instant discovery during AP image upgrade. APs with the controller-less preference role are deployed as controller-less APs.

Syntax

Parameter

Description

Default

all

Deploys all APs as controller-less APs.

ap-group <ap-group>

Deploys all APs in the specified AP group as controller-less APs.

ap-name <ap-name>

Deploys the AP with the specified AP name as a controller-less AP.

ip-addr <ip-addr>

Deploys the AP with the specified IP address as a controller-less AP.

ip6-addr <ip6-addr>

Deploys the AP with the specified IPv6 address as a controller-less AP.

wired-mac <wired-mac>

Deploys the AP with the specified MAC address as a controller-less AP.

Example

The following command deploys all APs as controller-less APs:

(host) #ap redeploy controller-less all

When attempting to run this command on an IAP-275 I received an error stating that this command is not supported on this AP model.

 

I have reviewed the very latest code version (8.3) and there is an addendum added to this command which states that this command only works on Unified APs. 

 

This is quite misleading as there is no mention of the unified AP limitiations in any of the 6.5 documentation. The outcome is that you can't confirm anything other than newer unified APs from CAP to IAP using this command. 

 

 

Hopefully someone at Aruba can fix up the documentation to make this clearer

That is because a little known "feature" of Instant 6.5.2 is if you load it on an Instant AP and factory reset it, every instant AP becomes a UAP. That behavior has since changed.

 

Most APs SOLD as UAPs (except for two models) require 8.x to function.

Re: ap redeploy controller-less doesn't work for non Unified APs

Hi Colin, it would be great if these caveats were documented. i've now got a customer facing  a very expensive exercise to factory reset over 50 access points which are all pole mounted.  this command had it worked as documented would have saved them thousands of $$

Re: ap redeploy controller-less doesn't work for non Unified APs

if i was to downgrade my contorller to 6.5.2.0 would that allow me to redeploy the IAP-275 which are already running as CAP or is this only if the Instant firmware is installed first?

I don't know, but it is definitely a corner case  situation that was reverted.

Why would they need to factory reset APs?  Is this controller-based or an Instant Cluster?

Re: ap redeploy controller-less doesn't work for non Unified APs

existing setup centrallised model with IAP-275 running as CAP on 7210 controllers. Customer moving to distributed Instant model and most of the internal APs are being replaced but the external IAP-275 are remaining and need to be converted from CAP to IAP so they can work with the local IAP cluster instead of the central controller.

They should use the wifi console to get into the APs console and attempt to factory reset it there.

Re: ap redeploy controller-less doesn't work for non Unified APs

Hi colin,

 

when you say wifi console are you referring to some inband method of accessing the AP console (i.e. not USB)?

 

i tried clearing boot params using the ap provision command but that just brought it up as default CAP.
