that the AP supports. You can look at retry frames. etc.

James,
Does Aruba state what is the last stable version? I am seriously
wondering if going backwards is an option because I am currently seeing some
issues as well, but I just upgraded a little over a week ago to 8.7.1.3. We
use 325's and 225's predominately. I haven't opened a ticket yet. I

Wireless managers,
We have some Aruba 325 AP’s in a gym and I am wondering what some of you
use to protect them from physical damage such as a softball ball, etc? Do
you use some sort of a cage? If so what? If it uses metal, does it
interfere with your signal strength?

I was told by Sertigo that all commercial certs would be affected. We just
bought the last 2 year expirations we could get away with for both 802.1x

The reason I am told has to do with so many smaller establishments that go
out of business before their cert expires leaving the cert as
Yep, that is exactly what we have had to do sometimes. Get both devices

move the 802.1x back to the preferred SSID. Sort of a pain. Many vendors

Bruce,
It has been awhile, but I recall having done it a couple times. We used
mac address authentication in our case. I remember though having Aruba
having to add in some code to the controller to allow it to work after
Sonos had done an upgrade a couple years ago. I would hope by now that
perspective? Ie. which protocols and such.

Vikki,
What are you using for a firewall? We had to open up a couple ingress
protocols after we upgraded our PA firewall. These protocols need to talk
to servers on the Internet. PA’s latest models will block the handshaking
unless ingress is open. We found this to be predominately true for
This brings up an issue where I have philosophically wondered if mac
address authentication isn’t better than 802.11x (wpa2). The reason isn’t
because it guards the network better. But if one does get hacked at the
point of accessing the network, the consequences are way less. One isn’t

It is a mixed bag for us. We have over 80 closets on our campus. If we
think a location has reliable power, we don’t bother and we just replace a
switch if something happens. We did identify 5 residential buildings that
have unreliable power so we put UPS’s in them. The other buildings
I think this is an excellent topic that has made me wonder. Given that so
many users don’t secure their radius client profile, I have often thought
mac address authentication might be a better option, but it would require a
convenient registration method. If someone uses a man in the middle
I agree with this sentiment. 2.4 is a long-run losing battle. We deployed
5 ghz nearly everywhere to minimize the need for 2.4. I observe that
2/3rds of all devices automatically use 5 ghz. So it really isn’t as big
of a problem as it could be. I expect that number to improve each year. I
Chris,
We use vlan pools in our Aruba wireless configurations to accommodate
our students. Normally, the same ip address will follow a student around
as they roam so that makes roaming easier. We have had problems with

You may want to consider putting in a UPS to make sure the power is clean

some of you handle this. Do you have a
method for blocking them?
Also, there are other products beginning to broadcast their own ssid as
well including printers, connectify, etc. How do you handle them? Do
you even have policy restricting those from your network?
