SMART-RF malfunctioning

winger — Thu, 10 Oct 2024 10:44:13 GMT

Hello, Extreme community!

We have a problem with the SMART-RF functionality in our deployment. In a nutshell, something is causing "Select Shutdown hide" in an RF-Domain that has its own dedicated SMART-RF Policy with "no select-shutdown" configured. We have multiple RF-Domains on our controller covering one region of the globe.

We are running: 7.9.0.1-007R on our NX-7530-100R0-WR controller and a mix of different firmware on the APs. They are like this:
ap7532 > 7.7.1.6-006R
ap7632 > 7.7.1.6-006R
ap305c > 7.9.0.1-007R
ap305cx > 7.9.0.1-007R
ap410c > 7.9.0.1-007R
ap410-1 > 7.9.0.1-007R

I have checked the local RF-Domain manager config for any possible config mismatch, and I didn't find anything different from what there is on the central controller. There is also no reason/indication from SMART-RF to hide the R1.

With that particular RF-Domain we also notice something funny. From time to time when show wireless ap on XXX is done, the result is empty. And after some seconds it's filled with data again. Anyone faced similar behavior? Here are the SMART-RF Policy details:
sensitivity custom

assignable-power 2.4GHz max 18

Morning winger,

If you are not trying to take advantage of Nova UI i would suggest upgrading deployment to 7.7.1.10.
If you are trying to get away from the flash GUI please update deployment to 7.9.5, the AP76xx APs will update to 7.7.1.10 as they are not capable of 7.9.x code.

Hello Daren,

thank you for pointing in the direction of the FW swap. We are considering it. I would really like to drop all of the non-universal APs: 7xxx series and stay with 310's/305's/410/460's. Unfortunately, this is not an option for us right now. I was looking at the SMART history from the controller and I got this:
% Error processing 'show smart-rf history on XXXX':
Traceback (most recent call last):
File "/bld/n03/workspace/ADVAP_n_CTRL/wing/obj/nx7-bare_metal/src/sys/cfgd/cli/show.py", line 130, in _show_read

Exception: Timed out waiting for remote device 1C.A2.2E.C0 xpath=wing-stats/rf_domain/XXXX/smart-rf/history

is it giving us any clue on where the main problem is?

It sounds like the RFDM (rf-domain manager) is not responding.
Do a "show mint neighbors" and a "show global domain manager" and ensure that the device reporting as the RFDM has mint id 1C.A2.2E.C0 and is function properly on the network.

I would try a quick reboot of that device and see if that helps.
