ARUBA 225 DHCP ISSUE

Hi All

 

I have a found a quirk with my Aruba Instant Wireless network.

 

I have 18 IAP 105's and 2 recently added 2 x 225's. One of the 225's has assumed master of the Virtual Controller but I found a quirk with random ipad/iphones trying to connect on the 225.

 

I receive an alert saying "

2014/3/21 12:28:47
90:b2:1f:c3:04:7c
DHCP request timed out
AP20 C BLOCK C2.

 

It then just gives it an IP address starting with 169.254._._

 

If i then walk over to another AP which is an IAP 105 and turn my wifi on and off my device it then instantly connects.

 

Does anyone have a similar thing happen or any ideas as to what im missing??

What is providing DHCP on that network?

What version of instant are you running?

Re: ARUBA 225 DHCP ISSUE

I ran into the same issue with IAP 225 running 6.3.1.2-4.0.0.3 specialy with the 2.4GHZ clients. the clients werent getting the ip address and in the VC it was showing DHCP request timeout.

1st i reduce the power but it didnt work well  and still the clients werent getting the IP address after that disabled the client match, on restarting the IAP i was able to get the ip address.

So far its working fine have to check the behaviour for some time.

Re: ARUBA 225 DHCP ISSUE

I am using windows Server 2008 R2 to give out DHCP. I have 2 of these running on my network.

 

The version of firmware is 6.3.1.2-4.0.0.4_42384.

Re: ARUBA 225 DHCP ISSUE

The version of firmware is 6.3.1.2-4.0.0.4_42384.

 

I am using windows Server 2008 R2 to give out DHCP. I have 2 of these running on my network.

I use radius to authenticate against windows AD.

 

I have 20 x IAP 105's and 2 x 225's. I have noted that the wireless network will not run cohesively unless one of the 225's is the master.

I use a virtual controller which is why we bought the IAP series in the first place.

 

Can you think of anything else which would help.

Re: ARUBA 225 DHCP ISSUE

When you say that you disabled the client match. What is that and where can I find it on the web interface of the VC?

Re: ARUBA 225 DHCP ISSUE

Can you share the output of ?show tech-support? from your virtual controller?

Re: ARUBA 225 DHCP ISSUE

I can get onto my virtual controller but where is the location of find tech support?

 

I find a section called support but it is blank.

Re: ARUBA 225 DHCP ISSUE

If you are in the UI, please click the ?More > Support? link, and then select ?AP Tech Support Dump? from the first drop-list, select the AP you are having trouble with in the second drop-list, and then click on Run to see the output.
