Cisco peer to peer Forward-upstream option
Hi, In the wlan advanced settings in cisco wifi, there is a peer to peer blocking option. We have used both drop ( no peer to peer ) and disable ( allow peer to peer ) but not the other option. Our security team are asking about the ability to put an IPS between wlan clients and I am thinking the forward-upstream option is the method to use. Has anyone used this option? If so how do you specify the upstream device? Cheers, Peter.

Radio specific client count report in Cisco environment
Hi, I was wondering if anyone has been able to run a report that identifies unused radios of using Cisco Prime 1.4. We recently found a room with two access points where a client couldn't connect. It turned out that even though the 2.4 radio reported as being on and functioning, no clients could connect. One stopped working a few weeks ago, and the other three days ago. The 5GHz radios were working fine and had clients associated to both access points. I ran the Client Count report for the affected floor from the Client Reports section and this was ok for a small area, as it reports all the access points in a graph format, and allowed me to select by radio type. It got me wondering how many other radios may have a similar problem. If I run this report for all our access points, there is no sort function, so you have to manually look through all the graphs. In the Device section, there is a Top AP by Client Count This is a handy report, as it gives a numeric output and can be sorted, but it seems to be total clients for the AP and there is no option to report on just specific radio type, so I can only assume that this report only reports access points with no associations on any radio. Any assistance would be greatly appreciated. Thanks, Peter.

RE: Controlling Bonjour Zones
Hello Jason, We also use Cisco. Like you we found the bonjour gateway features worked, but did not provide location control. In some cases our academics have multiple AppleTV's in the one location and don't mind that they are all available. In other locations, they only want to see the local Apple TV, so we have an ssid advertised with a name like ATV-P512 to let them know this is the apple tv for Building P room 512. This is a bit of a pain as we also have to create an ap-group for each apple tv. We are using 802.1x and found that if the ATV is powered off, it does not store the time and has issues accepting a certificate. For this reason we connect the AppleTV using the wired port, on the same vlan that the ssid terminates on. We actually had to turn off the bonjour gateway feature for these networks to achieve our goal. While this is not an ideal solution, it achieves the outcome we require. Peter.

I know other vendors have similar workaround features and am interested see how people have gone with it, keen to hear from users of other vendors as well. So far it all seems to work as advertised, was pretty easy setup with good control over what services you advertise. However I find there to be a lack of location control, and would like to know if anyone has implemented ways to control the location where the advertisements go. For something like this we'd like to restrict the advertisements to location by building/level/room/AP, it will help it scale better for users devices when scrolling through the list of available devices to connect to like an Apple TV. Users in building 1 don't need to see an Apple TV in a meeting room in building 2. Using separate SSID's is also not really a scalable solution... though does work of course with a dedicated subnet and multicast enabled. We currently don't have building based networks, which would be one way to control advertisements. This is something we are planning, but are a while off yet, also the ability to go more granular than just buildings would be useful. I've started a conversation with our local Cisco office, but am interested see what others may have done or believe could be useful for this.

RE: [WIRELESS-LAN] Apple and wireless connectivity issues?
Hi, We also experienced this type of issue when we recently enabled multicast on our Cisco wireless controllers. We are using WiSMs and after enabling multicast experienced a lot of odd issues. This caused ipv6 capable clients issues, even though ipv6 is not configured on the wlans. The main issue was for mac users, who could see other mac shares and had intermittent connectivity to google at various times. We are using 7.0.98.0 code on the controllers. After reading the release notes, I found that when multicast is enabled, multicast and ipv6 is not blocked by peer to peer settings and is forwarded by default. Bonjour uses both multicast and ipv6. Also we found a windows host acting as a ipv6 router, due to internet sharing being enabled. This caused the other ipv6 capable devices on the wireless network to connect and get an ipv6 address. As google have a entry the devices were trying to access it via the ipv6 network. Below is a discussion from other universities which have also encountered this issue. http://www.mail-archive.com/cisco-...@puck.nether.net/msg32671.html There is no support for ipv6 acl’s on the controllers in the current versions of code. To resolve the issue we had to disable multicast.

By default, these machines provide IPv6 router advertisements for their built in 6-to-4 tunnel. The Mac prefers IPv6 when available, sees these RAs and accepts that user's machine as its gateway. The users machine passes my traffic on to its gateway as tunneled traffic. Since I'm using IPv6, and it has converted my traffic through its 6-to-4 gateway, my traffic needs another gateway to get back to IPv6. I have seen times when the gateway it found was in New Zealand (I'm in Pennsylvania). Depending on where it dumps me out, I probably don't have an optimal path to my destination. In theory, the fix is to get people to turn of MSICS. In practice, its easier to get people to turn off IPv6. By the way, the MSICS issue should also exist for IPv4, since it includes DHCP offers. However, we have the ability to block this in our LAN. We do not currently have the ability to block RAs.

RE: [WIRELESS-LAN] Cisco WLAN Session Timeout
HI, I think the access points use this value to determine if hosts are still connected. Some time ago they changed the default to 0 sec. We do monthly reporting for maximum associations per access point for capacity planning. At that time the maximum associations for each access point was huge. In the next code release, they changed the value to 1800 seconds. Not sure if this is still the case.

RE: [WIRELESS-LAN] WIRELESS-LAN Digest - 19 Jan 2009 to 20 Jan 2009 (#2009-8)
Hi, We have been running 5.2 for a few weeks also. The main reason we upgraded was for support of the new 1142N aps. An issue the I noticed immediately after the upgrade is a lot of log messages for Potential honeypot rogues. The controller seems to think that different ssids on the some of our valid aps are rogues. This causes the controller to disable the radio interface briefly. Below is what the TAC engineer said about this issue: I found a bug filed by my teammate last month, for too many honeypot trap events on WLCs. Reported in code prior to 5.2.157.0, the good news is that DE have apparently determined the cause and coded a fix. The bad news is that they show apply-to: and integrated-in: fields of 6.0.x.0 which is not out until later this month or early Mar09. The other issue we encountered was the removal of the wlan override feature. This wasn't too big a problem in our case. AP Grouping is now the required method of limiting the distribution of wlans. By default all aps are in the default-group which advertises all wlans on the controller. We are going to use 3 groups, Production ( all our regular wlans ), Conference and Development. From the controller it is quite simple to move the ap's between groups, in the WLANS Advanced menu. Is anyone else using version 5.2 ? Regards, Peter.

WCS accepts spaces in the AP group name, however, the controller does not 2. WCS doesn't necessarily assign the correct interface name to the controller using and AP group. SSID name XY interface XY on the ap group template. Push it to the controllers and SSID name XY interface ZZ. So be careful with #2 in using AP Groups.

Fully realizing that some of the other lesser known 802.11 working groups (like .11r) are better suited for reference in this line of dialogue, I guess I'm thinking that at least on our campus, there's a fair amount of bus stop-and-go, considering all of the bus stops, stop signs, traffic-related slowdowns, etc. So if I had a shuttle route of say a mile and a half, the typical AVERAGE speed of the bus might be 10 or 15 MPH, despite the posted limit being 30.

Even bicycle speeds might be too much. For a modern day WLAN network to be a success (IMHO), they would have to implement Enterprise WPA2 and if you think we have re-authentication fun on a campus mobile level, I can just imagine doing this at a XX AP per second level while moving on a bus. I'd advocate that a per-bus Wi-Fi AP is the best architecture.
