Re: [WIRELESS-LAN] Cisco 11n users
Hi, I would be very interested if this subject discussion was kept open to the group. We just turned on an 11a/b/g/n service using a single Cisco 4402 with 16 APs (soon to expand to the max 50 APs a single 4402 will allow. It covers a residence, so it's not a high density area nor would I expect a lot of roaming between APs. We're running Ciscos V5.1 of code while I understand that most folks are at 4.3? No negative reports (yet?) but we do have folks using it. This is our first stab at thin APs.we have 800+ 350s and 1121s. I'll be happy to try to answer any questionswe're still sort of new at this.thx.JJames SavageYork UniversitySenior Communications Tech.108 Steacie Building[EMAIL PROTECTED]4700 Keele Streetph: 416-736-2100 ext. 22605Toronto, Ontariofax: 416-736-5701M3J 1P3, CANADA ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Cisco 11n users
Five 4404 with 230 1252s deployed (all have 2.4 5 radios) with the goal of reaching 350+ in January. Running Cisco's 5.1 code base. 5GHz running with 40Mhz wide channels. We went live September 1st with the bulk of the 1252s deployed in our residential halls. So far, I'd say that the deployment has been rather uneventful. All are in the same mobility group, and our peak concurrent user count is in the 800-830 range. We had some initial pains with Macs that employ broadcom-based airport cards where they would fall on their face if the AP was using channels between 52-140.

Re: [WIRELESS-LAN] Meru Networks
We have nearly 700 AP311s across our campus with at least another 400 going in over the next 6 months or so. We are using the MC5000s with the new accelerator modules. Overall, I'd say, the products have been stable and reliable. Currently there is an issue with the MC5000 chassis when it is fully loaded with these new blades, Meru is aware of the problem and looking for a solution. Also the current version of ezrf does not support the version of code on the controller that we are running, 3.6-111. This is a minor issue since it doesn't affect the actual operation of the network. We expect this to be resolved in the next week or so. On a more positive note, we have been able to get the latest version of Airwave to recognize the MC5000s and the APs attached to them, so we are getting the information we really like from there. -- Daniel Eklund Director, Network Engineering Wayne State University Detroit, MI 48201 Phone: 313-577-5558 Fax: 313-577-5577 ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
RE: [WIRELESS-LAN] Cisco 11n users
To extend Matt's question- how many are using 11n's extended range as a feature? What I mean is that we have most (though not all) of our designs based more on capacity than range. Even though 11n can give better range, not sure how important that will be when we still want less users on APs to preserve higher per-user throughputs. Though in some areas the better range will come into play and provide value, but these (for us) will arguably be in the minority. -Lee -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Barber, Matt Sent: Tuesday, November 11, 2008 3:07 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 11n users Anyone running 11n in the 2.4 GHz on the 1252s? 20 or 40MHz?

Do people deploying the 1252s find that 802.11a and 802.11g clients are getting better range and/or throughput? I understand that MIMO and MRC will improve the AP's receive sensitivity, making clients more visible, but I was curious whether this would apply to the downstream as well as the upstream.

RE: [WIRELESS-LAN] Meru Networks
You mentioned Airwave working with mc5000 and ap's. We have two 3150's with about 150 ap S (pretty small compared with yall). I am wondering if anyone has had any experience with Meru and Airmagnet? I have the spec analyzer card from cognio and that works fine but the laptop analyzer (now wifi analyzer) does not seem to do well with the single bssid architecture. Does anyone know how to extract the actual radio mac addresses from each AP so you can add to airmagnet and know exactly what AP is doing what? I know every radio (2 per ap) has it's own mac because the program can see them but I don't know how to find out which is for which ap. I can find the wired Ethernet mac for the ap's but not the radios. Any ideas?

We are using the MC5000s with the new accelerator modules. Overall, I'd say, the products have been stable and reliable. Currently there is an issue with the MC5000 chassis when it is fully loaded with these new blades, Meru is aware of the problem and looking for a solution. Also the current version of ezrf does not support the version of code on the controller that we are running, 3.6-111. This is a minor issue since it doesn't affect the actual operation of the network. We expect this to be resolved in the next week or so. On a more positive note, we have been able to get the latest version of Airwave to recognize the MC5000s and the APs attached to them, so we are getting the information we really like from there. -- Daniel Eklund Director, Network Engineering Wayne State University Detroit, MI 48201 Phone: 313-577-5558 Fax: 313-577-5577 ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.

Re: [WIRELESS-LAN] Cisco 11n users
We are running 11n in 2.4 GHz on the 1252's, but only at 20MHz. 40MHz in 2.4 MHz seems like a very bad idea because of the lack of non-overlapping channels. As for range, the building I'm in is a thick concrete/rebar construction and I can get about 120 feet (exiting the building) from an 1252 AP before I can't see it. That said, I'm designing based on capacity more than range. In the case that capacity is not an issue, I'm shooting for 50-70 foot spacing between 1252s to maximize 5GHz coverage. Jeff Barber, Matt [EMAIL PROTECTED] 11/11/2008 12:06 PM Anyone running 11n in the 2.4 GHz on the 1252s? 20 or 40MHz? What kind of range from the APs are you seeing?

We just turned on an 11a/b/g/n service using a single Cisco 4402 with 16 APs (soon to expand to the max 50 APs a single 4402 will allow. It covers a residence, so it's not a high density area nor would I expect a lot of roaming between APs. We're running Ciscos V5.1 of code while I understand that most folks are at 4.3? No negative reports (yet?) but we do have folks using it. This is our first stab at thin APs.we have 800+ 350s and 1121s.

Time-based rotation for TKIP ucast and mcast keys
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 In order to successfully mitigate the new TKIP attack, organizations need to turn on key rotation for stations, where each minute of key use represents one byte of plaintext an attacker can recover for a given packet. The consensus so far is that 2 minutes before the next key rotation (PTK, not PMK; no RADIUS involvement here) is reasonable. I've been looking around, but I haven't found if this is possible on Cisco, Meru, Trapeze or Symbol products. A friend at Aruba pointed out the steps for an Aruba 3.x controller: enable configure terminal aaa authentication dot1x profilename multicast-keyrotation unicast-keyrotation timer mkey-rotation-period 120 timer ukey-rotation-period 120 Does anyone know if this is possible on Cisco LWAPP AP's, Cisco autonomous AP's or other vendor products? I'm collecting this material for a SANS webcast on Monday.
