AP70 unable to get elf file

Hello,

in our environment we set up the wlan controller OAW-4308 with firmware AOS-W 5.0.3.3.

Now we started to connect our older AP-70 to the controller. Not directly to the controller but over a separate subnet. One of these got connected and provisioned just fine but a lot of the AP-70 get stuck in loading the elf file from the controller.
Following steps we have done:

AP-CLI, AP-Boot:
# purge
# setenv serverip #IP-Address#
# setenv master #IP-Address#
# save
# reset


The APs got their IP from DHCP and here's the console output after reset:

The IP connectivity is quite correct and our firewall logs shows nothing was blocked.


Anyone here a suggestion to solve this without connecting the APs directly to the controller?

Re: AP70 unable to get elf file

What physical infrastructure exists between the access point and the controller? Is the access point connected to a POE switch? If these access points are older, why don't they have an older image on them? TFTP is only copied after a factory reset..

On the controller, please see if the access point is truly connecting via tftp by executing:


"show datapath session table 10.1.1.20"

I am assuming 10.1.1.20 is the ip address of the access point. That will show if TFTP is even getting to the controller.

Is that controller beyond capacity?

Re: AP70 unable to get elf file

Thanks for the quick reply!

The APs never used before because they came out of our reserve repository.

The APs are connected to a POE Switch but is this relevant? No problem to connect them to an ac-adapter.

Here's the output code:

(OAW-4308) #show datapath session table 10.1.1.20

Re: AP70 unable to get elf file

I would connect it directly to the controller, because you say a firewall is involved. Does the firewall do any natting function? TFTP does not like NAT :(

Re: AP70 unable to get elf file

Ok, connect these APs directly to the controller is a bit complicated cause it's installed in our data center and only a few persons have access.

So, the firewall has a any/any rule for provisioning time. No NAT configured at all. Simple Routing connection.

Is there no other way to get the image to the AP?

Re: AP70 unable to get elf file

- Is this controller up and running right now, with access points on it?
- Are those working access points on the opposite side of the firewall?
- Were those other access points provisioned the same way?

Yes

Yes, quite correct!

- Were those other access points provisioned the same way?
Yes, but the other APs already have had an image.

Re: AP70 unable to get elf file

Unfortunately, based on your setup, your access points probably have to be on the same side of the firewall for the access points to get that image over tftp.

Re: AP70 unable to get elf file

So I try to get access to the data center, maybe takes 1-2 days...

Thanks for your help, maybe someone comes a straight solution to flash the image without controller to mind...

Re: AP70 unable to get elf file

There is a way, but you might run into the same issue that you are having now to copy the tftp file.

You can use a tftp client/server to copy the mips.ari file from the controller to a laptop (you might NOT even be able to do this).

After that you setup the AP to boot from tftp and point it to the laptop with the mips.ari file:

apboot> setenv master apboot> setenv serverip
apboot> setenv bootcmd tftpboot
apboot> save
apboot> boot

After it loads, change the bootcmd variable back to bootap, and the master and serverip back to the controller:

apboot> setenv bootcmd bootap
