You would think there should be a near-hitless upgrade process.  Could be as 
simple as temporarily restricting APs from downgrading.  And that doesn't even 
have to be done the AP side, that could be done via a setting on the WLC.

I have seen the APs jumping between WLCs running different code levels and 
downloading different codes during upgrade as well. Then I came out this 
upgrade procedure and it seems no more looping:

1. On WLCs management interface vlans, remove the ACL entries which permit APs 
to join the WLCs. 
2. Download new codes to all WLCs from WCS at once.
3. Reboot all WLCs from WCS once.
4. Put the ACL entries back. 

Then you just watch the APs joining WLCs without looping.

Cisco would suggest to shut down all wisms port channels during upgrade and do 
upgrade through service port. That is the same idea to prevent APs from joining 
WLCs before the upgrade finish.

Has anyone seen much iPad action on their networks yet?

I heard today that we have around 10 of them doing Active Sync with email.

We had a couple of support calls early Monday indicating problems with our
Impulse/SafeConnect NAC system identifying them properly. Since then Impulse
put in a patch that apparently fixed it. Our xpressconnect config tool
worked fine using their tool, choosing the same option that configs iPods,
etc. We have also been testing our own iPad today and haven't seen any
issues yet. We noticed that the Apple's auto config worked as well for our
own 802.1x network, with the caveat that it made it possible for someone to
fake the certificate.

RE: [WIRELESS-LAN] Cisco Wireless Controller Feature Gaps

2010-04-26 Thread Frank Bulk - iName.com
AFAIK Aruba doesn't insert itself in the IPv6 path, just like Cisco, but it
does bridge the traffic fine (using it right now).  I'm sure Aruba has more
in the works, but I haven't asked/sought for that.

In terms of IDS/IPS vendors, I just engaged TippingPoint on this and they
wrote that "the N-Family devices (660N - 5100N) support IPv6, including
tunneled traffic from 4 -> 6, 6 -> 4, etc." and "currently the plan is the
TP10 will be able to support IPv6 sometime around the end of the calendar
year"

As for load balancers, these are my notes:
A10 Networks: today
Barracuda Networks: nothing on website; told one customer in Q1'10 or
earlier that IPv6 is in the works, and when asked for sooner, "they told us
it's based on customer demand and maybe by end of year [2010]."
Foundry (Brocade) ServerIron: they support IPv6 in the 11.x loads.
Coyote: "We can commit to the fact that the Coyote Point Systems Equalizers
in production today (GX platform family) will support IPV6.  I suspect that
the earliest you will see this capability is 4th Quarter 2010."
F5 BigIP: Yes
Kemp: does not have a solution, though it is on the horizon [stated fall of
2009]
Radware: Yes; just bringing out the new image for allowing DS on a single
interface. [stated spring 2010]

Subject: Re: [WIRELESS-LAN] Cisco Wireless Controller Feature Gaps

James, we are currently running IPv6 on all of our campus wired and wireless
networks (WiSM's).   The WiSM's simply bridge IPv6 traffic to our routers.
Essentialy, there is no IPv6 functionality within the WiSM.  This is
problematic for many reasons, but the biggest is that IPv6 users can bypass
our web authentication if they only use IPv6 services.  Secondly, there is
no mobility solution for IPv6 users which has caused problems for clients.
We peer with "Google over IPv6", therefore any IPv6 problems are noticed
very quickly.  We felt the risk that we assume was acceptable enough for the
short term inorder to help push the IPv6 adoption on campus and to provide a
use case for vendors that aren't there yet.

The WiSM product manager gave us a roadmap on where IPv6 is headed with the
platform, but I think it was under NDA, so you'll need to ask your account
team to get you that info.  

I am not aware of any vendor that currently supports IPv6 for the wireless
space, although Aruba did announce upcoming support for it.  The vendors
seem to be in no hurry to implement it, so keep demanding it as a necessary
feature with every opportunity.  This applies to all vendors, not just
wireless.  An extra loud 'Hello' to IDS/IPS and load balancing vendors!

I'm aware it's supposed to do IPv6, but have heard rumblings on the
grapevine that it doesn't do it in a functional sense -- is anyone using
IPv6 in production with Cisco WLCs (WiSMs in our case)?

If indeed the community believes this to broken, then that would be lacking
feature for me.

Re: [WIRELESS-LAN] locate the rogue AP from wired side

2004-02-17 Thread Frank Bulk - iNAME.com


If you want to do some distributed wireless security monitoring, you might want to look at a solution from AirDefense or AirMagnet.  Network Chemistry has a cheap monitoring solution.
 
As for wire side detection, it's rather difficulty because the Ethernet MAC may or may not be the same as the wireless MAC.  Many times they are within plus/minus 1, but not necessarily.  They could be from two different sets.
 
Probably the easiest way to identify which room is to do some rough triangulation, or, use a laptop, associate to the AP, ping from inside your network to your laptop, and then trace the route to your laptop's MAC.

Re: [WIRELESS-LAN] locate the rogue AP from wired side

2004-02-17 Thread Frank Bulk - iNAME.com


I don't believe that Netstumbler catches devices that hide their SSID.
 
While Cisco's WLSE 2.5 identifies rogues, it's not a solution I would get just to identify rogues.  WLSE remains primarily a configuration system for AP's.  Of course, if you already have Cisco AP's, then WLSE is a no-brainer.  
 
Wireless containment is a nice feature, but few have it; only Aruba's wireless switch can auto-contain.  The rest it's either manual or in consideration for implementation.  The vendors can all do it (it's just a DeAuth), but there are some liability concerns, obvious in situations where your system is on the 10th floor of a 25 floor building.

I just read in a Cisco PowerPoint slide that according to a META Group 2003 report, 15% of WLAN's TCO is CapEx, while the last 85% is OpEx.  These numbers are probably more accurate for for-profit corporations, but there is probably some truth for schools, too.  If an organization spends $750 per access point with a 3-year life-cycle, and has a deployment of 300 AP's, that works out to be $425K per year in operational expenses.  That seems quite high.

I’m trying to get a sense of the costs associated with operating a WLAN, specifically as it relates to “physical” maintenance of a network with 100s of APs.
In other words: 

How often does one need to “touch” an AP for maintenance purposes (upgrade, replacement, configuration, debug, reset, etc.) ? 
How much time does one typically “spend” with the AP in the above cases and how is that time impacted by the fact the AP is in a hard-to-reach place (e.g. ceilings) ?

Hello,
 
I’m new to the listserv.  I read somewhere that the AP’s maximum speed for all clients is equal to the lowest connected speed, i.e. if one person connects at 1Mb then all users on that AP connect at 1Mb.  Is this true?  If so, that would explain why some of my clients end up with low speeds and great signal strength.  If this is vendor specific, we are using Cisco 350 and 1200’s on campus.

Re: [WIRELESS-LAN] [WIRELESS] Most un-wired campuses

2004-04-08 Thread Frank Bulk - iNAME.com


The study includes several aspects, if you look at the bottom of the link:

"The "Most Unwired College Campuses" survey findings are based on the number of hotspots, the number of undergraduates, number of computers and the computer to student ratio. The results were also based on the percentage of each college campus that is covered by wireless technology. The data was collected from university interviews and documents, and a variety of industry sources."

 
I was surprised to see that Syracuse University was included, considering that the wireless coverage here is not 100%.  It shows that 100% campus coverage is not a prerequisite to getting on this list, and shows the relatively lack of deployment in colleges and universities nationwide.

Re: [WIRELESS-LAN] Wireless site survey tool

2004-06-03 Thread Frank Bulk - iNAME.com
Title: Wireless site survey tool


Nas:
 
I've tested Surveyor, and it works quite well.  It's based on the concept of active and passive surveys.  The active survey associates to an AP and record packet loss, signal strength, and connection speed.  The passive site survey listens for all APs and their beacons, and can only record each AP's signal strength from where it is.  While the product can't auto-discover, it is amazing to see that with a good 'walk', you can narrow down the location of the AP to about a 20' x 20' area.  The heat map shows it quite clearly.
 
Maps can be based on bitmap, jpeg's, and as well as AutoCAD drawings.  The product does require the use of one their support cards, so it is somewhat vendor specific.  Supported cards should be on their website.
 
I think that Ekahau's product can do something very similar, but for a few more dollars.  Trapeze's RingMaster is more a site planning tool.

AirMagnet has a new tool called Surveyor that they demonstrated at InterOp; I think it's out, and the list price was in the $2K range.  Runs on a laptop. I haven't looked at it yet but it does look like a good tool for site surveys.  I don't think it (or any product for that matter) can "auto discover" the exact location of an AP, but the resulting survey of signal strength and distribution should be enough to "figure out" where it is.

Cisco's new WLSM

Cisco released their new WLSM module for the Catalyst 6500 a few weeks ago.  I work for a magazine and we are examining this product and it's related components.

2004-07-01 Thread Frank Bulk - iNAME.com


Matt:
 
That's a good question about the SUP720 requirement, the same one that we had.
- From what what we were told, previous SUP's did not have support for hardware-assisted Multipoint GRE tunnels.  There is a tunnel for each mobility group associated with an access point.  Mobiltiy groups are somewhat equivalent to wireless VLANs or SSID's.  So if your network has three SSID's on each of your 100 AP's, you would have 300 multipoint GRE tunnels.
 
Besides this performance requirement for tunneling, there are also the benefits of:
- user based rate limiting
- resource limiters
 
There are likely more reasons, but I have forgotten.  
 
As for inter-WLSM roaming, that's correct.  If you have 500 access points you'll need to associate half the AP's with one WLSM, and the other half with the second WLSM.  Roaming times in the 50 ms range (using CCX v2.0 cards, of course) will only occur between AP's associated to the same WLSM.  I expect Cisco to increase the number of AP's they support per line card as well as solve or mitigate the inter-WLSM roaming issue.  Of course, there is no guarantee of that, but it's a reasonable assumption.

RE: [WIRELESS-LAN] Cisco's new WLSM

2004-07-01 Thread Frank Bulk - iNAME.com


Matt:
 
Has Cisco's solution ever been cheap? ;)  
 
Let me detail a few of the list price costs (educational institutions should be able to get at least 35 and up to 45 points off list).
WLSM: $18K
minimal incremental licensing costs to go from 150 to 300 AP's: $8K
Firewall module: $35K
SUP720: $28K
Cisco's point is that their competitors don't scale, so for a deployment of several hundred AP's, where their competitors would need to add management/control boxes, Cisco wouldn't.  Of course, their competitors claim scaling in the 20 to 130 range.  Whose numbers do you believe? I really don't have the answer for that.
 
I didn't see any user monitoring per-se with the solution, but I can imagine that the WLSE box (another $5K, I believe) can do something user related.  I'll have to look at this.
 
Each GRE tunnel can be prioritized on a per tunnel or per packet basis, and rate limiting of the contents can be done via their SUP720's support for user-based rate limiting which can one an IP address or a larger group.
 
Although the WLSM is the actual aggregrator of the RF measurements and rogue information, administrator interaction concerning rogue detection, power levels, RF management is done via the WLSE box's web interface.

Re: [WIRELESS-LAN] Cisco's new WLSM

2004-07-02 Thread Frank Bulk - iNAME.com


Jeff:
 
Let's be clear that the WLSM is not superset of WLSE's features.  The WLSM is an advanced WDS, and the WLSE will continue to play an extended role in managing access points, monitoring for rogues, load-balancing power, etc.  You don't need the WLSE to run the new WLSM blade, but most organizations will use that 1-U management solution.  
 
You make a valid point about vendors and the numbers of AP they support.  I think the reason they are so flexible is that the number is so variable.  It's dependent on how much traffic will traverse the switch, how many client sessions it needs to maintain, what kind of encryption will be used, the rate of roams, if clients are using just 802.11b or 802.11a/g as well, etc.  There is so much variety that all the vendors numbers can be qualified.  Each vendor will have some kind of bottleneck, whether it's the encryption processor, host processor, the data plane (a 100 Mb link could theoretically scale only to 4 saturated hi-speed links), or the control plane.  So vendors aren't being totally arbitrary when they crank up their numbers to get a deal or hammer out a licensing agreement.  Each organizations environment will be different.  In all of this there is a subtle warning: don't run the demo or pilot and prematurely call it a success.  Dense and pervasive deployments (both of AP's and clients) will likely discover the limits of these systems, so it's wise to deploy carefully, with plans to change the ratio of AP's/clients to controllers if performance becomes a problem.  I've had several vendors share customer stories in which the pilot ran well, but once they got into a dense deployments (or started using VoWLAN) the problems started appearing, and they decided to move to a new vendor or change their site design.
 
Of course Cisco shops will experience the best integration of Cisco-specific features between the wired and wireless networks, but that's to be expected, and why some organizations go with a single-vendor solution.  It's the client side of the wireless world that's difficult to control, most apparent in an educational environment.  I know that Syracuse University strongly recommends the Cisco 350 card, but that doesn't mean that's the only card students use.  As you stated, once you use non-CCX cards the roaming benefits of the Cisco solution are mostly lost.  But you still have the management of AP's and traffic control.
 
Competing solutions like from wireless infrastructure switch vendors have to be vendor-agnostic because they don't control any other part of the wired network.  You may call them Cisco-proprietary features, while Cisco will says it's the extra value it adds to the solution...they might even say that they provide a superset of features.  They might also say that the reason that some thing are proprietary is because Cisco has to provide solutions in response to customer demands while standards move slowly through the standard bodies.  It's the same thing in every product and industry.  At the end of the day, the customer needs to choose for themselves what's appropriate.
 
Could you elaborate a bit more on "Ask Cisco to demonstrate all their Aruba and Airespace -alike features when the only clients on the network are authenticating with EAP-TTLS/PAP"?

When you get down to brass tacks, some vendorsare willing to throw out the "we can't go more than 32 APs on this boxbecause it's a performance limit" and jack up the licensed number ofusers to accommodate your budget requirements.

This was about five years ago. Along the way, wireless throngs joined the mix.At that time we did a rather thorough analysis of ISC, Lucent's QIP, Nortel's NetID, Cisco Network Registrar, and Microsoft's built-in DHCP server. We decided on NetID, and we have been largely very satisfied with it for the five or so years that we have been running it. Our runner up was QIP, which is also a very impressive product. However, we returned to ISC this year as its fail-over and load-balancing features have come a long way and we wanted to move away from Solaris to Linux. We currently run both NetID and ISC, but our wireless network (about 5300 users and 830 APs) is being served by ISC. We intend to phase out NetID for our campus by year's end.ISC is a very good option, and you can't beat the price or the ubiquity. It probably has more road time than any of the others; I'd venture to guess that only Microsoft could come close in terms of installs. I don't know anyone using Microsoft for a significant deployment, so in terms of users served, it is ISC, hands down, imho.ISC still has many shortcomings, however. Some notable points are its relatively poor support for a database engine backend and its virtually non-existant user interface front-end. There are lots and lots of tools for it, though, as it has been around in the open-source community for so long, and it is extremely stable. I encourage you to consider ISC, NetID, and QIP.Consider the choice of failover carefully. Even 700 users is significant enough that you don't want any downtime for your DHCP server ... this is just as important as any piece of equipment in your core network, because if it breaks your users don't work. We've had occassional anomolies, but for all intents and purposes we've had 100% uptime for five years (in that, for the last five years, no user has every failed to get an address due to server unavailability). This is the mark you must hit for DHCP.

Re: [WIRELESS-LAN] Authentication/Encryption revisited

2004-09-09 Thread Frank Bulk - iNAME.com


Don't some SSL VPN's require some kind of ActiveX control to provide encryption for non-web-based applications?  That would neccesitate a Windows computer.
 
Of course, if the service being provided is web-based and can do SSL, then it's a nice easy way to secure your traffic Layer-3.  But your Layer-2 traffic is still in the clear.
 
Phillipe Hanset makes a good point about 802.1X's ubiquity.  68% of our ResNET uses Windows XP, 3% use Windows 2000, and 3% use Mac OS 9/X.  Thirteen percent recorded 'don't know', so many of them could be Win2K/XP.  That means at least 3/4's of the student population can use their OS' native 802.1X client.  Wait until next academic year and the numbers will be much better.  For the other older Windows computer there is even WIRE1x:

Add Cisco's ACS to provide the intermediate LDAP authentication, and you have a solution.

FCC Clarifies OTARD Rules: College Dorm Exemption Still Applies=
 
On June 24, the Federal Communications Commission’s Office of Engineering and Technology (OET) issued a Public Notice (DA 04-1844) concerning the use of unlicensed devices (such as WiFi access points). The Public Notice stated that unlicensed devices are subject to the same consumer protections for the installation and use of consumer antennas under the FCC’s Over-the-Air Reception Devices (OTARD) rules as, for example, satellite TV dishes. The OTARD rules allow tenants to install such devices in areas subject to their exclusive use and control.
 
ACUTA immediately contacted the OET staff on this matter, due to our concern about the potentially negative impact of “rogue access points” on campus wireless networks. The FCC had stated in a previous Order that campus dormitory housing is exempt from the OTARD rules, because it is not a typical residential lease situation. Through our attorney, we contacted the OET staff to express our concerns regarding the Public Notice, and to seek clarification that the exemption for college dorms was applicable to unlicensed devices.
 
We are pleased to report the OET staff response that, “…the Public Notice does not change prior Commission interpretations of the extent to which college dormitories are, or are not, covered for a particular customer antenna installation.”
 
Thus, colleges and universities may continue to legally prohibit students residing in campus dormitories from placing unauthorized antennas for licensed services (such as broadcast or satellite television) or unlicensed services (such as WiFi).
 
However, in cases where the institution enters into an actual lease of residential property (such as student apartments or faculty homes), the exemption does not apply. In such cases, the resident would have the right to place antennas within their leased property.

Re: [WIRELESS-LAN] Vanderbilt Residential Housing RFI

2004-10-30 Thread Frank Bulk - iNAME.com


I guess what my concern is that if you make 48 Mbps your minimum rate you'll need an access point in each room. ;)
Even at 36 Mbps, I'm guessing an AP in every second or third room.
 
VoWLAN can be accomplished via several means.  One way is to use one band for it, ie 802.11a for voice, and then 802.11b/g for data.  
 
Another way is to enable QoS.  The reality is that Cisco phones can handle only 6 or 7 active calls per 802.11b/g AP, and the Spectralink phones about 10 to 12 calls.  A G.711 call takes only 70 to 80 kbps on the wired Ethernet side, and if you add the overhead of the larger 802.11 frames, ACKs, etc, it's in the low hundreds of kbps per media flow (two flows per phone, of course, one upstream and one downstream).  RF contention is the issue rather than bandwidth as more phones are added.  When 802.11e is ratified it should include scheduling, which WMM does not have, which should allow for higher handset densities.  In the meantime, Meru Networks claims that with their own unique scheduling algorithms they have the ability to increase the density of handsets by at least 5x.

I'm impressed that you get the higher rates that you do, but drywall likely helps a lot.  When you mention the 60 to 80 foot radius, what do you consider the higher 11a date rates to be?  24 and up?
 
I know of one other Meru implementation at a university, but they are not on this listserv.  Another school using Meru is Auburn University Engineering School and SUNY Stony Brook, but again, I don't think they are on this listserv, either.

Re: [WIRELESS-LAN] Wireless Management

2004-12-31 Thread Frank Bulk - iNAME.com


The 'brains', if I understand what you are describing, are already offered by the wireless switch vendors.  They are past L2-roaming and on to L3-roaming, and if you use Cisco's stuff with CCKM, you'll get fast secure L3 roaming.  
 
How big is everyone's L2 wireless domain getting?  The nice thing about identity-based access, which Airespace, Aruba, and Trapeze all offer to different extents, is that wireless users can use just a single SSID, but based on a RADIUS attribute be put into a specific VLAN.  That offers some managment advantages over creating separate SSIDs for every department.  But I'm still in accord that a separate (and broadcasted) guest/visitory SSID is appropriate.

With Cisco's APs you can only broadcast one SSID, and you only have one BSSID.  It's in situations like you are describing that this becomes a weakness in comparison to vendors such as Airespace, Aruba, Symbol, Trapeze, etc that support multiple BSSIDs.

RE: [WIRELESS-LAN] Single mode/single fiber connectivity options?

I know that a service provider vendor, Calix, also has a GBIC to do this.

It's not an uncommon thing to do anymore.

Subject: [WIRELESS-LAN] Single mode/single fiber connectivity options?

Hi,

I need to connect a building to our campus that is about 5-6 miles away. We
will be leasing a single mode fiber connection to the location, and
connecting a Cisco 3750 stack back to our Core 6509. Using a single fiber
instead of a dual fiber connection will save us $12,000/yr.

In looking of ways to do this (connecting GBIC in the core to the SFP in
the 3750), I came accross the following:

http://www.championone.net/pdfs2/SingleFiber40km.pdf

They have a single mode/single fiber GBIC that can connect to their single
mode/single fiber SFP. I called the company, and they said the applicaiton
should work, we would just need to add an antenuator to the fiber
connection since it is rated for 40 km.

Has anyone used this company, or have other ways of making this connection.

Thanks,
Alan Carlson

I second the QuickBridge.  The Alvarion B-series of products should be looked 
at, too.

Lih-Er,

We have used the Proxim Tsunami Quickbridge product for some time now and are 
very happy with it.  However, it's going to cost you at least twice what you 
have budgeted.

I need to bring network to a structure (2-story) in a field from a building 
(about 1000 feet away, 7-story).

It does not need high bandwidth. I would like to hear any product 
recommendation from you.

The budget range is under a $1000 for a pair of wireless bridge. I am more 
concern about the reliability and security sides

of the product.

By the way, does anyone have experience with NanoStation5 from Ubiquiti 
network?  It is quite inexpensive ($160 a pair).

Thanks!
