APs unable to adopt to Controller RFS6K v5.8

[dot1x]

Hi Champs!

Our client having issue where the APs at one of the sites are not joining the controller. Though the APs are up and running, serving the clients as well but we can’t see them online on controller.

We can ping the APs from the controller CLI and vice versa.

Another thing we noticed yesterday, when we logged into GUI of an AP, we could see rest of the APs there.

Any thoughts?



RFS6000 v5.8

AP Model: AP7131

In case any low bandwidth WAN links are present between the remote sites with high latency and packet loss, it is recommended to increase the default MiNT Hello Interval and Adjacency Hold Timer on both AP and Controller Profile. Usually hello interval value of 60 with adjacency hold-time of 180 should suffice on high latency links, but in some rare cases it may be extended to 120 hello interval and 360 adjacency hold-time.

Access Point Profile Example:

!
profile ap7532 default-ap7532
autoinstall configuration
autoinstall firmware
interface radio1
interface radio2
interface ge1
interface vlan1
ip address dhcp
ip address zeroconf secondary
ip dhcp client request options all
interface pppoe1
use firewall-policy default
use client-identity-group
default controller
hello-interval 60 adjacency-hold-time 180 service pm sys-restart
router ospf

it's configured as

controller host pool 1 level 2

If that is the case this knowledge article should help~
What is recommended MINT MTU size?

By the way, for remote site AP, you should be using

controller host level 2
