Re: [WIRELESS-LAN] iOS 8 drops tomorrow
If you have access to OS X Yosemite Beta Server you can install an Apple cacheing server on this OS. We are trying to set one up here in anticipation of the downloads. Apple is shy on the documentation for this feature so if anyone can share any success in this setup please pass it along to the list.

The student may not even know there's an access point there. This won't work for everyone, since the big Aruba/Cisco players don't have this form factor. We're small enough we don't even have a controller and use fat APs. But I thought this was still worth mentioning for those with mixed environments or anyone using Ruckus or Extreme..

So we can take some time to fix the problem (referring to the room access issue). As Larry mentioned, we used to have many complaints with our hallway 2.4 GHz design, we have almost none with our bedroom 5 GHz design. The cost is different of course! BTW, good luck to have a decent coverage at 5 GHz if you plan to cover from the hallway. The attenuation is atrocious! It is hard to reach the room, and APs see each other in the hallway forcing the RADIO algorithm to reduce power.

Re: [WIRELESS-LAN] Odd issue with Aruba wireless...
I just ran into a very similar problem and debugged it with Aruba support. Please check your user-table for the IP address of your server. (Aruba) #show user-table | include ip-address If you see an entry in the user-table check to see what role it is assigned. My SMTP server kept showing up and was being put into a role that would now allow SMTP communication. DOH! The fix is to add the ip address of the server to the validuser acl. configure terminal ip access-list session validuser host ip_address_of_server any any deny position 1 write memory This will modify the validuser acl and tell it not to add the IP address of your server to the user-table. Let me know if this fixes your problem also.

Do a packet-capture on the client to confirm continuous ARP requests for default gateway with no responses. Then, mirror the port on the Aruba controller and see if the ARP response from the default gateway at least makes it that far. With those two data points, you should be able to continue tracing the path to determine where it is dropped. == Ryan Holland Network Engineer, Wireless Office of the Chief Information Officer The Ohio State University 614-292-9906 holland@osu.edu Submit a Kudos to an OCIO employee!

Re: [WIRELESS-LAN] Aruba ARM 2.0
We have been using the 3.3.2.x code line for a while now. We have not enabled any of the advanced ARM 2.0 features yet. We are also experiencing some weird issues with Macs on the N APs. Every once in a while our MacBook Pros will throw up an alert that says Your Wireless LAN has been compromised and will be disabled for one minute. Is this the same thing you are seeing?

Re: [WIRELESS-LAN] Vendor Choice

I have narrowed my choices down to Cisco and Aruba. We are planning on creating three roles which are faculty/staff, student, and guest.Each of these roles will have varying degrees of access to systems on the network. Because of manpower issues we will be broadcasting the SSID and using Novell's LDAP to authenticate to the system. We are not a Cisco shop so there is no advantage either way as far as dropping into our existing system. My question is are there any gotchas I might be missing with these two vendors? From what I have seen, both systems seem to work nearly identically. You can access the same information from each controller, and both are self-healing when an AP goes out. Are there any support issues I should be aware of? We plan on making our decision around the first of November, so I look forward to any comments this group might have. -- * Jay Howell Executive Director of Information Technology Chowan University Ph: 252-398-6361 * ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http:// www.educause.edu/groups/. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http:// www.educause.edu/groups/. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
