IAP restarting

Hi guys,

 

I was trying to connect to the Instant SSID of an IAP which has no uplink connection. I have read in other post in order to do this possible, I have to assign a static IP, and that is what I did.

After assigning a static IP by console, the IAP boots and after a while starts broadcasting the Instant SSID, I can connect, but after a couple of minutes the IAP restarts and I don't know why. I attach the console output. What's happening?

Re: IAP restarting

What do you plan to do with an IAP that has no network connectivity?

Re: IAP restarting

Hi Colin,

 

I want to completely configure some IAPs at office, and once configured bring the IAPs to customer site and connect them to its network for fast deployment. I don't want to waste time at customer site. But I can't do this because the IAP keeps restarting.

 

Regards,

Julián

Re: IAP restarting

Hey, can you try running "show version" after one if the times the IAP has rebooted? There will be a line that gives you the Reboot Time and Cause, this might provide some clues.

 

Also try deleting the Instant SSID and creating a test SSID to configure management. I have seen instances where the "Instant" SSID has uplink/OOS configuration causing the AP to reboot unless the Instant SSID is removed.

Re: IAP restarting

Hi zailon0,

 

I issued "show version" after the IAP has rebooted and this is the output:

 

a8:bd:27:ca:79:14# show version
Aruba Operating System Software.
ArubaOS (MODEL: 325), Version 6.5.1.0-4.3.1.0
Website: http://www.arubanetworks.com

Compiled on 2016-12-15 at 03:19:05 PST (build 57768) by p4build
FIPS Mode :disabled

AP uptime is 3 minutes 21 seconds
Reboot Time and Cause: AP rebooted Thu Jan 1 08:08:12 UTC 1970; Current uplink down, no useable uplink

 

Therefore, you cannot access the WebUI when there is no uplink connection because the IAP reboots. Then, there is no way to configure an IAP wherever you are if there is no a Ethernet connection.

 

On the other hand, I have done the second option, to configure a SSID and power on the IAP and check if it reboots, and indeed the IAP reboots anyway. Attached the output of this second option, you'll see the cause if the same.

Re: IAP restarting

Have you tried enforcing the uplink? 

 

To enforce an uplink:
1. Click the System > show advanced settings > Uplink. The Uplink tab contents are displayed.
2. Under Management, select the type of uplink from the Enforce Uplink drop-down list. If Ethernet uplink
is selected, the Port text box is displayed.
3. Specify the Ethernet interface port number.
4. Click OK. The selected uplink is enforced on the IAP.

 

This should ensure that eth1 is always used regardless of the uplink. I've never test this feature but do you want to give it a go?

Re: IAP restarting

Hi zailon0,

 

I will try and let you know. In the meanwhile I have other question. As I told you, I have configure a SSID and also a static IP, netmask and default gateway on the IAP. When running the "show running-config", I can't see this configuration in the output, why not?

Re: IAP restarting

Hi zailon0,

 

I have tried enforcing the uplink. It seems the IAP lasts a little more, but finally it reboots anyway. Before rebooting, you can see this line:

 

[  169.275007] ip_timer_handler: ignore uplink port state, wifi uplink 0- 3g uplink 0- enforce eth0 1

 

After rebooting, I have issued the "show version" and now the cause is the gateway is unrecheable. Whatever the case may be, if the uplink is not connected, the IAP always reboots. Attached the output.

Re: IAP restarting

Hi Julian,

 

The static IP parameters are AP specific & will not be listed in the running config

 

You can view them using the following command

 

show ap-env

 

For the other issue, is the ethernet LED lit up on the IAP as I can see the messages related to "Ethernet uplink not active".

 

Without detection of physical link, IAP will keep rebooting.

Re: IAP restarting

Hi Nitesh,

 

Thanks for the configuration question.

About the issue, this IAP has no Ethernet LED, but in any casethe IAP has the uplink disconnected on purpose. I wanted to test if the WebUI can be accessed when the uplink is disconnnected, and I have confirmed it can't be, at least with this model and firmware.

Julián
