MSM760: APs are slow on getting synchronized after controller reboot

hpbon — Wed, 16 Dec 2015 15:49:15 GMT

Wifi was reported slow, so I decided to reboot controller. After controller reboot LED on most access points are flashing sequential and one hour since the controller is back up after reboot, only 4 AP are syncronised.

Is it normal to take so long? Do I need to de something to speed op process?

Regards, Lars.

Hi.
When this problem started happening? How many apps you have on the environment? What is their status now? Is there any error log? The controller and ap's are on the same network?

I am having 35 APs and a license to 40

This is the first time I am booting the controller, so it is the fist time I am seing it.

Before I went to bed 9 APs were left unsynced. This morning 3 are left unsynced...

Is this normal behaviour?

Regards, Lars.

The documentation is written that all apps receive the new firmware at the same time ....
How is the Controller and network consumption?

But I haven't firmware upgraded it - the controller has just been rebooted.

Network seems ok

I can confirm that APs take a troublingly long time to come online again - particularly if you change firmware versions; you can have a couple of hours of downtime across a larger site (we have over 70 APs, which suggests wireless is important to us) before things work again.

It's not really good enough, and I struggle to understand why pushing out firmware "updates" and "updating configurations" takes as long as it does.

How is your access points configured to reach the controller?

Are the APs static ip address or dhcp?

Manually set or via dhcp or all aps and controller on the same vlan?

Are the APs Discovery set to the controller ip address?

I have 4x controllers and 400x APs and software upgrade from 6.5.0.0 to 6.2.0.0 took 30 minutes for upgrade, firmware flash to AP and syncronize.
