Jumper Settings on cisco wireless APs (1010)

I noticed the other day that there are jumpers inside the 1010 APs and I was just curious on if anyone knows what they are for. I've searched the net with little luck on finding a document that explains this.
It's all just morbid curiosity, but who knows- could be handy information to know.
Thanks!

That is how you can access the vxworks shell.
It is quite limited though
We originally looked at the airspace solution when nortel was reselling them..
I played around with a sacrificial 1020 a while back.
There was some doco available before cisco bought airspace, but it seems to have dissappeared.
There may still be some info in google cache for some airspace info @ a year or 2 back.
Here is what I found

Snow Leopard 10.6.4 and unable to get IP address from Wireless APs

I have a MacBook Pro with 10.6.4 and just recently ran into an issue in connecting to Wireless APs. Many of my corporate APs with WPA2, etc work great. I even have some great success at customers of mine with Cisco APs and open authentication (ie., Guest access).
However, I have been having alot of problems with generic APs (Linksys, etc.) For example, I have been in two hotels in the past week and I would connect to the AP, but I would only have a self assigned IP address. I have no problems at Starbucks.
I have tried to turn airport on and off, rebooting with no success. I have also disabled my firewall with no luck. The problem is very repeatable.
What do you think?

You might try resetting your connection settings using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take a minute or so to try.

Issue with Cisco Meraki APs

Is there any known issues with Cisco Meraki APs with client devices which publish PMF support in probe requests ? We are seeing connectivity issues with Cisco Meraki MR12,MR16 and MX80 models . Please update if there are any known issue with these APs.

Thanks for your thoughts, Nathan. We do actually have the "Enable Fast Reconnect" option selected on our wireless profile. Good idea, though.
We did also (originally) have 2 RADIUS servers defined within our wireless network. What we discovered was that each Meraki AP will try each one in order, top-to-bottom, and then primarily use the server that responded to it first. So, if for any reason you have a short-lived issue with your local RADIUS server responding to requests, and the AP is able to talk to a remote RADIUS server (in our case, one on the other side of the world) instead, the AP will elect to use the remote RADIUS server instead. In our case, the latency is high enough between these APs and this remote RADIUS server that while a client is roaming between APs, and having to re-authenticate, the entire process breaks down because (1) the client is moving between APs faster than the remote RADIUS server can authenticate the client, and (2) the entire exchange and communication ends up timing out -- thus forcing a manual re-connect. This is not a common occurrence by any means, but I just wanted to share what made us later choose to define only 1 RADIUS server, in the network settings. Surely our circumstance here is rather unique, but I thought it might be worth mentioning. Having only 1 RADIUS server defined forces ALL of our APs to use the same RADIUS server, regardless of anything else. It has resulted in a much smoother re-auth process for our clients.
I appreciate the link you sent, however. If I come across anything else that is helpful, I'll certainly post it back here. I appreciate your input once again!

WLAN Clients not browsing on Cisco Wireless Controller WLC NME-AIR-WLC12-K9

HiI have a question and i need a solution and expert help.I have done a deployment which involves Security (ASA5540), Routing/voice gateway/wlc NME-AIR-WLC12-k9) and Switching (Cisco3845-ccme/k9)Below is the list of equipment used:1. Cisco ASA 5540 - which is connected at the edge to the ISP router
2. Core Switch WS-C4948E as core and DHCP Server for all VLANs
3. Access/Distribution Switches WS-C3560G-48PS-S connected as trunk to the core switch
4. Router/Voice Gateway/WLC Cisco3845-CCME/K9 - This is the voice gateway and also the WLC
5. Wireless APs AIR-LAP1242AG-E-K9 (12 qty)Here is the deployment scenario:1. G0/0 of the ASA is connected to a 7200 router from the ISP (Public IP Add)
2. G0/1 of the ASA is connected to gig 1/3 on the Core Switch on VLAN 2 which is the management VLAN (Local IP 10.1.1.2)
3. Port 3 of the Core switch is on vlan 2 connected to ASA - Management IP of Core Switch is 10.1.1.1. Core Switch is the DHCP Server for all VLANS on the network.
4. All the Access/Distribution switches are configured with IP Addresses on VLAN 2
5. Telephony Services is configured on the router and DHCP Pool for Access Points and Wireless Clients is running on the router.
6. Two DHCP pools were created on the router for APs and Wireless Clients.
7. G0/0 of the router is configured on the same network that issues dhcp ip to the AP and is connected to gig 1/1 on the core switch
8 G0/1 of the router is configured as the voice port for the IP Telephony Services and is connected to G 1/2 on the core switch1. Clients receiving DHCP IP on the Core Switch can communicate with all vlans and can browse to the Internet.
2. IP Telephony Services is running well.
3. Client on wireless can get IP from the DHCP on the router but cannot browse.I have pings from the router to the core switch and firewall, but clients connected to the wireless
cannot ping other vlans on the core switch and vice versa.The port connecting the router to the core switch is an Access Port, i have changed to to trunk but still no changes.My biggest problem now is how to make the clients on the wireless communicate with other clients on the network and be able to browse to the Internet.Below is the configs on the router and core switch.Router ConfigNimc_Voice_Router#sh run

Please i need somebody to help me

I wouldn't configure an ip address on the service engine subinterface.
Try setting up a vlan interface on the router with that ip address and the subinterface will be linked to the vlan interface through the encapsulation command. A vlan interface will better work as a gateway for the wireless clients

Cisco wireless and Apple Mac woes

Hello all,
I've been working with Cisco wireless and WLC's for a couple of years now but the recent onslaught of Apple Mac's is giving me heart burn. I've seen this at numerous sites now and need to throw it to eht community for guidance.
Basically we have had a number of instances where the Macs just fall off the wifi. Sometimes it's when they wake from sleep and other times when roaming between AP's (1131s with same SSID's). Our standard install is WPA2 and per ap local authentication. PC's work fine and never an issue.
We have completed a survey with a spectrum analyser and no RF interefence is present nor errors on the radio interface.
Questions:
- Is there a preferred Cisco config/setup for Mac's to work reliably? I've heard loads of rumors but nothing concrete and nor can I find anything specific.
- Should I be setting up WDS in case there is an authenticating issue.
- For those who are Mac gurus and happen to be reading. What Mac options we should look at?
This has all come to a head because the clients IT company who recommended the Macs (different from us doing the network infrastructure) are insisting that the problem is Cisco incompatibility and that we should rip out the Cisco kit and install airports (what tha!!!).
Thanks in advance for any pointers.
For those who like a config here it is .... Vanilla stuff really

Yeah!! even i have come across multiple issue with MAC and Cisco.. these are the below settings which i normally do on the cisco gears and most of the times this solved the issue..
on the IOS AP disable Aironet Extentions and set the poer local and ofdm to max
no dot11 extension aironet
power local cck max
power local ofdm max
end
On the WLC, disable Aironet IE..
lemme know if this answered your question..

MacBook Pro will not connect to Cisco Wireless Network

I have just bought a brand new MacBook Pro, running Leopard (OSX 10.5.1) and I just cannot get it to connect to the Wireless Network at my workplace.
The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. It appears to be an Apple issue.
For reference, my old Vaio PC, my Nokia N95 and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
It has to be a bug in Mac OSX... doesn't it?!?
Things I have already tried (following suggestions on many forums):
* Switching Airport off/on
* Deleting various network-related Plist files and rebooting
* Manually assigning an IP Address (not really permitted but doesn't work anyway!)
* Disabling all network adaptors except Airport
AP Grapher shows that the MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
Can anybody please help? Thank you.

i posted this same reply elsewhere because it worked for me for my Buffalo wireless router: try manually setting your IP address instead of relying on DHCP, which sometimes (I don't know why) doesn't work well with Macs. It's a good get around. I am a happy Mac user but nothing is perfect on earth, and when the Mac gives problems, it does give a lot of frustration. Macs are not as easy to troubleshoot as Win because a Mac is built to be user friendly(and it works most of the time), meaning a lot of the background computing stuff is hidden away from users to avoid user accidentally upsetting some settings.
Unfortunately, the highly automated troubleshooting wizards provided by OS X are not perfect so when these software wizards fail to resolve the problem, like my Network Diagnostics, I have to spend more time tinkering around. There's "Terminal" of course but then most of us, especially PC converts to Macs, don't know how to use it.
You should also try updating your MBP, see if there are any new updates being released.

I have an iPad with iOS 5.0.1 that is not able to connect to cisco wireless networks at work.

Hi, I have an iPad that is not able to connect to any of the Cisco wireless access points at work. The iPad is on the latest iOS 5.0.1. I did a reset on the iPad and erased all content and settings. The wireless network I'm trying to connect uses WPA2 Enterprise encryption. I'm able to connect to a Verizon mifi device so I know wireless is working. It seems like it's just not getting the certificate. I'm able to connect to our wireless network from other iPads just fine except for this one device. Please let me know if there is anything else I can do to troubleshoot the issue. Thank you.

I suggest updating using iTunes on your computer (current version: 11.0.3).
Update iOS first, then apps.

Advanced Settings to Improve Wireless Range (Fragmentation, RTS, and beacon interval)

I've got a WPA wireless network set up that utilizes a total of 4 WRT54GL routers as access points (on channels 1, 6, and 11 [the two APs furthest from each other both utilize 11). Each AP generally supports about 5 clients at a time (though sometimes as high as 10).
Generally, everything is working, but the clients furthest from the access points occasionally lose their connections, and some users have reported periods when they are completely unable to obtain an IP. I am virtually certain that this is based on poor signal strength resulting from distance from the APs and/or RF interference from other APs in the building. I have done everything possible to improve signal strength by router placement, optimizing channel usage based upon RF surveys, and upgrading to high-gain omnis.
This leaves nothing to do apart from tweaking the advanced wireless settings to marginally improve problems related to weak signal and/or RF interference, so I've been reading everything I can find on these boards and elsewhere about changing Fragmentation Threshold, RTS threshold, and beacon interval. However, I'm left with the following questions.
1) There seems to be disagreement about Fragmentation threshold and RTS threshold settings. Some (including the Linksys Technical Troubleshooting Wizard) recommend that both be set to 2304. I have also seen people insist that Fragmentation be set to 2306 and RTS to 2304. A few recommend 2306 for both thresholds, and some advise 2306 for Fragmentation and 2307 for RTS (though by my limited understanding, it simply disables RTS when the value is higher than the fragmentation threshold value). Which of these settings is best? And more importantly, WHY is it the best? Generally, I understand what the settings do, but I am reluctant to change them when there doesn't seem to be a consensus about exactly what they should be.
2) With respect to beacon interval, I've seen both 75ms and 50ms recommmended to replace the default of 100ms. For a network of my size (4 APs, averaging 5 users each), will increasing the number of beacons (and hence the RF traffic even when the network is idle) pose a problem? Also, I'm a little less clear as to how this would improve connectivity.
Since these settings will affect all users, I want to make sure that I'm using settings that will be beneficial on the whole. The last thing I want to do is inadvertantly make things worse, and since I can't test things directly from the standpoint of each user, I was hoping that someone could explain to me in greater detail what settings I should try and, more importantly, why.
Thank you for your help!

I changed my Beacon, RTS, and Frag values to the above values and now I'm unable to connect to the wireless network anymore. I tried to match the RTS and Fragmentation settings in my wireless utility (Hawking Wireless - RT73) to the new values, but I can't connect anymore. I didn't see anywhere i could change the Beacon number in the utility, but I wonder if that is my problem... Any ideas?
I have no internet, no network connection. I can connect to other networks in range, but even though the network with these altered Beacon/RTS/Frag values is detected, I cannot connect to it. I can send packets but all received packs fail. (CRC Fail, I think)
I can't get back into the web setup for the router, so is there anything I could do from my end? Find an adapter that lets me configure the Beacon setting?

Cisco Wireless Implementation

Hi,
We are in process of deploying cisco wireless infrastucture using WLC 5508 and AP1252. However, just curious to know what are Cisco best practices regarding VLAN design for these components. Can they belong to same VLAN or we need to provision separate VLANS for WLC and APs.
Appreciate your early response.
-> Ripu

500 APs will be fine. The number of clients isn't an issue here, it becomes more of an issue depending on the setup of your wireless infrastructure, you probably wouldn't want 1000s of users on one big flat network.
Hope this helps,
Thanks
Chris

Cisco Wireless NAC Appliance - Design Practices ??

Hi,
I have a new Cisco WIreless NAC appliance, the purpose of which is to manage the Guest users access to network. I have been searching for some best practices related to the design of this appliance but havent found one.
Can anybody help me in sharing his design experience or any docuement which would be guiding in deciding over the design / placement of this NAC device in network.
Thank You.

Hi,
there is nothing such as "Wireless Nac appliance".
The question is "do you have the NAC Guest Server" or the "Nac appliance Server and Nac appliance Manager (CAS/CAM)" ?
Because those are just not the same at all.
Then on the wireless side, do you have autonomous APs or a WLC ?
Sorry to ask, but there's just so many possibilities you could be asking that we need to clarify.
My bet is that you are either looking for this :

Network ready for Cisco wireless ?

I know for IPT their is lots of network readiness guides. Is their anything like that for Cisco wireless (with central controler)? We looking at putting in Dell swithcs and not cisco. Anybody have any switch level feture I should be looking out for?

For autonomous you would likely need less features on a switch then with autonomous access points. I'm not a fan of Dell switches, but at the edge they should be fine. With the lightweight APs you don't have to trunk to the access points ('cept H-REAP configs), so you could potentially plug them into hubs!
I would probably look for a PoE midspan if you are not using the new 3560E swithes. Microsemi sells a managed hi-power midspan that support all Cisco access points all the way up to the 1250s (and assumptively beyond). Purchasing 802.3af PoE now seems like a bad idea.

MARs and Wireless APs

Has anyone configured thier MARS appliance to monitor wireless APs such as a Cisco Aironet 1240? As of Version 4.2.2 there are no wireless products listed under device type. If someone has this configured which device did they use?
Thanks.

bobsills,
This is absolutely possible. We have all of our wireless APs added to MARS. Simply add them as a Cisco IOS 12.2 device and MARS should be able to log in and manage the devices. We have everything from 1200s to 350s monitored via MARS. Ensure that you're using IOS on the APs, as older VxWorks ones cannot be managed by MARS. Any other questions I can answer please let me know.

Need Help on Cisco Wireless Solution!

Hello Netpros!
I have some issues that probably most of wireless implementers faced after implementing a wireless solution. This is an actual feedback from the customer and These issues can be broken down to the following:
1. The wireless Network is slow! (wireless performance)
The customer has Airtight in placed and airtight reports that users are mostly connected to the wireless network on 2 mbps speed. Users also says that their network experience using wireless are slow compared to wired network.
My question is what reports or guides that cisco wireless cotroller system or WLC can shows that proves the network is working as it is intended. Any guides on how to improve the user experience? Any guide from Cisco IT?
During these slowness, what reports from WCS or WLC that can best shows the problems and helps us implementers to mitigate the problem?
2. Baseline Wireless Performance.
When asked about a baseline performance of wireless network, what reports from the WCS or WLC that can show this and what is the acceptable or baseline values?
3. Is there a general guideline on how to use WCS or WLC reporting tools to troubleshoot a wireless performance issue? What reports to see? and how to translate that to say to the customer that the wireless network is under performing?
The main reasons i am asking these questions is because i cannot find any useful documents in cisco that guides the wireless implementers on how to use the reports generated by WCS or WLC when it concerns the performance of the wireless.
Most of the reports WCS generate that relates to the performance normally rounds up the AP performance, channel, noise, but how to translate that to user concerns is another matter.
Perhaps these issues are partly due to user expectations or maybe the wireless setup need to be tweaked or even might requires a spectrum analyzer to pinpoint interferences.
In either cases, I hope netpros can help direct me to good documentation albeit from cisco or other sources that can best outline wireless performance reporting using cisco wcs and wlc.
Background information:
The wireless network setup has one WCS, one location appliance, 4 WLCs and around 150 to 200 APs, most running Local and some running HREAP. Most of the issues concerns the local type APs.
Thanking all in advance!

Yup,
thats what we told the customer and even showed them the wlc/wcs reports.
Unfortunately, these customers are lacking in wireless knowledge and they want a streamlined, documented steps to generate the reports and also to help them understand in laymen terms.
At the moment we are formulating a holistic approach to the customer to get them understand wireless first, get them to have a policy and enforce and then drill down to management, reporting and troubleshooting.
The thing is, the wireless is always working fine, but sometimes so it happens some bigshots unable to connect to the wireless network in meeting rooms or somewhere and the become jumpy and pointing fingers.
So the IT manager wants to reduces the finger pointing by having the WLC/WCS to produce reports to them.

Cisco Wireless Cable Modem & Time Capsule

Hi,
I am having problem extending the cisco wireless modem using time capsule.
1) I am trying to wireless extend the range in time capsule but it hit error like "can't extend this wireless".
2) Since I hit error in 1), I try the Join wirelss setup. I can successfull join the wireless network but I could not use the ethernet port.
Any advise, please.

If you have not already done so, perform a Factory Default Reset on the Time Capsule (TC) to get it back to a known state.
Resetting an AirPort Base Station or Time Capsule FAQ
Then before you hook up the Time Capsule, make sure that the Ethernet port is working correctly on the AirPort Express (AX) by connecting a laptop to the Ethernet connection. Turn off the wireless on the laptop and see if you can get an Internet connection. If you can, the AX and the Ethernet port are working correctly.
Connect an Ethernet cable from the AX to the WAN port (circle of dots or world icon) on the TC
Open AirPort Utility, select the TC, and click Manual Setup
Click the Time Capsule tab below the icons to assign a name to the TC, device password and adjust Time Zone settings
Click the Wireless tab
Wireless Mode = Create a wireless network
Wireless Network Name = Same name as the Cisco network if you want more coverage under that name
Check mark next to Allow this network to be extended
Radio Mode = Auto
Channel = Auto
Wireless Security = Exact same setting that the Cisco network is using...if you want more coverage...etc.
Wireless Password + Same password as the Cisco network
Confirm Password
Click the Intenet icon, then the Internet Connection Tab
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings, wait a minute or two, then power off the entire network and restart again, starting with modem, then Cisco, then AX, then TC, then other devices.
If you want the TC to provide a different wireless network than the Cisco, then assign a different name to the Wireless Network Name on the TC.

Disabling WPS on Wireless APs via Firmware Modification

Greg Ose posted on the procedure if anyone wants to use it.
http://blog.nullmethod.com/2012/01/disabling-wps-on-wireless-aps-via.html
See, greg Ose already has a patch out - well, he can certainly disable WPS and that's most critical right now. Ok, Cisco now have a go at it.

While this is interesting, I'd suggest it makes a lot more sense to look at the latest "tomatousb" firmware for the E4200. It is very solid as-is, no mods needed, and well tested, much less risky. Just upgrade to it, empty the NVRAM via the "configuration" menu, and start configuring it. You'll have to do this part anyways, so you might as well avoid the risky step of modifying Linksys firmware, and go for pre-made firmware instead.
Both routing and wireless works very well, with no WPS implemented. There is also USB and media server functionality which I hear work well, also. I haven't used them. And you can do things like setting the transmit power of your router, but be careful with that *smile*. You can also monitor various usage parameters, way beyond Linksys firmware fuctionality.
Works real well for me and for many others as well.
