I had to get a controller replaced due to bad memory. Well the wlc cisco sent to me had the Russian LDPE image on it. Which wouldn’t allow me to upgrade the code to non LDPE image. I found this doc explaining the issue and also the fix for the problem.

Cisco IPSEC VPN Client for Android

Curious to know what others are doing for Cisco VPN Access from their Android Devices: As far as I know VPNC Widget will work if the device is rooted. I am trying to get "Samsung Anyconnect" working, it appears to successfully authenticate but then disconnects me - I think this might be a license issue or something on our ASA?

Apple Petition- Mid-Week Sanity Check

July 11, 2012 | Lee Badman

Folks,

Those interested seem to agree that we’d discuss specific pain points regarding “those other” Apple devices like AppleTv and any AirPlay/Bonjour-dependent gadgets until Friday, at which point we’d firm up the petition and find a place to host it. Then would come signatures, and ultimately presenting it to Apple, possibly via each of our Apple reps.

Neil Johnson has started the companion Facebook group, and has drafted the early version of what everyone appears to want from Apple development in petition form at https://www.facebook.com/groups/enterpriseairplay with 72 members joining thus far. (Thanks, Neil)

Apple TV/Wide Area Bonjour question

Good afternoon -- I had a question about how you setup Wide Area Bonjour -- in your example below you listed a dns record for _appletv-v2._tcp: 35CF2488F02660B1._appletv-v2._tcp SRV 0 0 3689 utnet-appletv.bonjour.utexas.edu. ; Replace with unicast FQDN of target host 35CF2488F02660B1._appletv-v2._tcp TXT "txtvers=1" "hG=00000000-06f6-4f5d-0171-0bcc51d34d14" "MniT=167845888" "fs=2" "Name=utnet-appletv" "PrVs=65538" "DFID=2" "EiTS=1" "MiTPV=196611" What is the number prefixing the ._appletv-v2._tcp?

Apple Petition

July 6, 2012 | William C. Green

Today it is AppleTV, tomorrow it will be a different device/use/software. The underlying issue, as others have noted, is the Bonjour resource discovery mechanism, what Apple likely needs is a directory service. Once that is solved, the problem will then shift to authentication/authorization/accounting and scalability. I'd suggest:

That Apple create non-Bonjour/non-multicast discovery mechanisms that scale in large enterprise environments.

That Apple integrate their offerings with enterprise AAA services.

Institutional Policy on radio frequencies

July 6, 2012 | Brian Helman

I’m researching policies regarding the governance of radio frequency control at other institutions? This seems to pop up annually here where a department goes for a convenient/cheap installation of a product, which inevitably means the device – weather station, score board, energy management – is 2.4GHz. And we tend to learn about it AFTER it is purchased and installed.

What I’m trying to find are institutional policies regarding who governs/identifies/recommends/etc wireless devices, whether 802.11 or not. I would like to present this to my management with the hopes of heading off “wireless” surprises.

Thanks,

shielding 2.4 from interference

July 3, 2012 | Peter Murphy

Wayne State http://wayne.edu has been getting complaints concerning wireless connectivity, especially in our Allied Health building. We may have found the problem with a spectrum analyzer: a magnetic imaging machine adjacent to some of the larger classrooms was completely over-powering 2.4GHz channel 11, and showing across the band. I am seeking some suggestions for shielding, which I will pass along to that Dean. I have seen paint, paneling and curtains. Replacing wall panels is probably out, as they do have some lead shielding for some of the medicines involved.

FlexConnect and Multicast

July 3, 2012 | Listserv Anonymous User

Message from me@mpking.com

So according to *many* release notes, I've found the following.

If you have a FlexConnect access point, your controller must be set to Multicast-Unicast mode in order for the Flexconnect to get the multicast traffic from the central controller.

I have an interesting corner case, that I'm currently unable to test (do to my lack of a multicast infrastructure) but would love to know the answer to.

If you have a FlexConnect AP, which is locally terminating traffic on a VLAN, and that VLAN is multicast enabled, would the multicast traffic still get forwarded?

Outdoor wireless questions

July 2, 2012 | Ethan Sommer

We are again considering deploying wireless outside, but we feel like we keep running up against inherent contradictions that we don't know how to solve. Here are the expected "problems" we anticipate" 1. If we put high powered APs outside, then they will cause interference with APs inside, and indoor clients might try to connect to them because they seem "stronger" even though they'd have a better connection to the indoor APs. a. How do you deal with the interference problems between high powered outdoor APs and indoor APs? b. Do you use the same SSIDs indoors and outdoors, and if yes, do indoor clients connect to the outdoor APs? c. If you have a seperate "outdoor" SSID, to client wireless network priority lists ever cause indoor clients to connect to the outdoor network? 2. We currently use one VLAN per building, all on the same SSID. Clients outside might hop between APs that are on different buildings, but not re-request a new DHCP lease. a. What VLAN should we put...

IPv6 only SSID with Cisco

June 8, 2012 | Dan Brisson

I searched back through the archives but haven't stumbled on to anything regarding this topic, and now that World IPv6 Launch day is behind us, I'm curious if anyone has setup a v6 only SSID in a Cisco WLC environment. It seems like a good way for folks to dip their toe into IPv6 and the controllers seem to provide decent support in the latest code releases. I'm also wondering about using NAT-PT for this SSID. I suppose we could just dual-stack our existing SSID, and maybe that makes the most sense, but I'm not sure I want to take that leap yet. Anyone with some experience in either or both of these areas willing to share?

WiFi Direct

November 5, 2012 | Listserv Anonymous User

Message from craigsimons@sfu.ca

How does everyone plan on dealing with Wi-Fi Direct from both a policy and a technology perspective? From an RF management point of view, I can't imagine a situation where it would be possible to individually manage all devices, printers, projectors, etc that can create Wi-Fi direct networks. And while an official policy might be able to steer frequency usage, it would be pretty tough to enforce without an existing sensor/countermeasures infrastructure in place (of which I would also assume 802.11w will eventually make useless anyway).

Yet, part of me wants to recommend it as the "official solution" for screencasting (ie Miracast) rather than fight a losing fight with AirPlay and mDNS over wireless.

My sense is that all TVs, projectors, printers, and BYOD type devices will eventually support it and managing the...

Where To Put Multicast ACL

October 26, 2012 | Listserv Anonymous User

Message from curtis.k.larsen@utah.edu

We have Cisco WiSM1's and WiSM2's deployed in a very centralized manner. While they are in physically separate datacenters, they connect to a single distribution block. All WLC Mgmt interfaces are in the same VLAN. Years ago, when we first turned up the multicast on wireless (mainly to support Vocera Push-to-talk) we chose to use unique multicast group addresses for each controller - thinking this would reduce the amount of total mcast going to each AP. We are in multicast-multicast mode, and use pim-sparse. Over time, as I am sure many of you have seen - the multicast just keeps growing. I have since discovered the ability to apply multicast ACL's to controller interfaces, and WLAN's so that I can keep clients from joining unnecessary multicast group addresses, and still allow Vocera's group address or Airplay to our Apple-TV on our specific AAA override subnet. Unfortunately, there is still some multicast that I...

Perhaps it’s because it’s Friday, but just getting PI 1.2.0.103 up & running and I see that when within the GENERAL dashboard,

I cannot scroll all the way to the right to see the edge of the dashlets on that side.

I thought it might be quickest to just ask this group.

Anyone else seeing this? or is this just a user error as I get accustomed to the new interface ;-)

If I minimize all dashlets on the left, then I can see a bit more of it.

I’m seeing no difference between IE/Chrome (most current revs).

If I drag/drop the right-side dashlets to the left , then I can see the entire thing – I suppose I can move them all to the left hand side.

sizing NAT and leases for the explosion

This is official, we have almost reached the capacity of our public IP addresses (20,000 just on Wireless) We love IPv6, but for the moment it's not going to solve our issue! So, NAT it is, and we have zero experience besides our visitor network that handles 1000+ users. Our plan is to terminate NAT on our Fortinet firewalls, and assign 32 VLANs (in our Aruba VLAN pools) with a private /21 in each subnet. So ~64,000 IP addresses. We block mDNS etc... no worries there. We can now move away from the 30 minutes lease time and go to... I was thinking 12 or 14 hours. We plan to do NAT-PAT 1 public to 8 private IP ratio or 1 to 16.

Just an update on the issue with that 3Com site which contacted me last week….

I’ve not heard back from this guy, despite several emails to him.

Another IT guy with a 3Com infrastructure also contacted me saying they were running into similar problems: interestingly, when they disconnected the 3Com APs from the their switch, everything worked fine. It turns out, THIS network is using the H3C gear that 3Com had started to license and resell before the HP acquisition – this was NOT legacy 3Com WLAN equipment.

I passed onto him a comment sent to me by an HP guy, speaking unofficially: he says there is a known issue related to this for the H3C equipment. He didn’t elaborate because it’s not his area of expertise...

Dot1x/WPA2 and machine authentication

August 3, 2012 | Joseph Roth

We are in the process of rolling out the Cisco Identity Services Engine as well as a WPA2 SSID, and have run into an issue, I did some research online and have not come up with much so I was hoping someone else could shed some light on this...

By default Windows will first attempt to do machine authentication, and then if this fails it should move on to user authentication. We have Cisco ISE joined to our domain, and so the domain machines that connect to our WPA2 SSID successfully do machine authentication. However, machines that are not joined to the domain that fail machine authentication (which they should) will at times throw up an authentication failure message in Windows, but not prompt for a username/password to authenticate to the SSID. Sometimes they do, sometimes they don't, it is inconsistent. In Windows 7 if we go into the Advanced settings and specify that it use username/pass only, it works fine. I believe that the default is machine and/or...
