Blinking IAPs in Airwave

Hi!

I manage 4 open WLANs with access to Internet. Networks worked properly (in AirWave there was always 100% SNMP and ICMP uptime) for about 1 month since it was deployed. But now some networks are blinking in their status, below is AMP events from Airwave one of WLANs:

Wed Mar 19 10:04:49 2014SystemStatus changed to 'OK'

Mon Mar 17 15:04:50 2014SystemStatus changed to 'OK'
Mon Mar 17 15:04:50 2014SystemUp
Mon Mar 17 15:04:50 2014SystemTunnel IP changed from 192.168.0.17 to 192.168.0.12.

 

Sometimes there is: Status changed to 'AP is not associated to Virtual Controller'.

 

Can you tell me what cause this behaviour? It can be link from external vendor (20Mbps symterical), which in the same time provide DHCP server?

Thanks in advance for help.

Re: Blinking IAPs in Airwave

We do not have enough detail about your deployment to provide any advice.  In general it shows a connectivity issue between Airwave and your IAPS.  In order to understand what is going on here, we need more information about your deployment and topology.

Re: Blinking IAPs in Airwave

[ Edited ]

There are 4 sites, in every site are 4 IAPs connected to Internet link via switch. Every WLAN is cofigured as open (no authentication, works like hotspot) and every virtual controller is connected to Airwave, config below:

Re: Blinking IAPs in Airwave

If all sites were good and now they are not, I would look at the site where Airwave is located.  What is the bandwidth at that site?  What is the bandwidth at those other sites?

Re: Blinking IAPs in Airwave

I have no information about Airwave site, i have only access in monitor mode (external company manage this platform). In my WLAN networks, there are three sites with 6Mbps symetrical, and one site with 20 Mbps symetrical.

Re: Blinking IAPs in Airwave

If there's a lot of network latency between sites, then it's possible that fine tuning the HTTPS timeout under Group -> select group with VC -> Basic tab -> Aruba Instant settings box.  Alternatively, if you open a case with support, they can help determine the relative latency between the APs and AirWave -> from the AirWave perspective (this is done by enabling additional logging to track all packets received from the Instant APs, then tracking the time between messages for gaps larger than the default 5 minutes).

Re: Blinking IAPs in Airwave

I will try contact with somebody who manage Airwave. Your assumption can be true, because in site where is 20Mbps symetrical and the same avarage number of clients like in the other sites (where is 6Mbps),  there is 100% SNMP and ICMP uptime through whole time.

Re: Blinking IAPs in Airwave

For IAPs, SNMP uptime is less important due to the difference in how AirWave communicates with IAPs.  By design, IAPs send packet updates regularly to AirWave over HTTPS not SNMP.  This moves the information exchange from a request based exchange to an announcement style where the IAP gives updates at 5 minute intervals (with 1 minute check up heartbeats).

Re: Blinking IAPs in Airwave

To be sure, ICMP Uptime means, how much (in observation time)  IAPs, responses to the ping from Airwave? I'm thinking about set limit (actually now there is no restriction) max bandwidth for user and for whole SSID to that level, to provide good communication between IAPs and Airwave.

Re: Blinking IAPs in Airwave

Correct.  The AMP will occasionally ping devices to check for uptime.  I'd have to investigate some more, but I believe that IAPs do not adhere to the ping test.  I have a feeling that IAP up-ness is only related to if we are getting update packets over HTTPS.
