L3 connections between Access points and WLC

hi,
we have a customer asking us to configure wireless system as per attached drawing.
WLC is in Data Center which is connected to Data Center Switch ( Cisco 3850), then this DC-Switch is connected to DC-Core ( Cisco Nexus-7K).
this Nexus-7K is connected to many campus Networks. in all campuses there is Cisco 4507 Campus Core which is connected to Nexus-7K.
then from Campus core many distribution switches are connected.
all Vlans for data and wifi is created in Distribution Switches. Distribution Switches are VTP Servers and many access switches with connected APs are connected back to this Distribution Switch.
All Access Points are registered at WLC in Data Center, but wifi clients are not getting ip address from DHCP Server, as well as even if we configured static ip address at wifi clients they are not able to communicate correctly.
please correct me if there is a mistake in this design , or we have a solution to solve this problem please let me know.
attached topology diagram
thanks,
anvar

Hey Anvar,
Too much details about network, to make it simple:
1- APs and WLC can be in separate VLANs (Not a problem)
2- As APs have joined, these two VLANs look fine for me
If your clients can't communicate probably with static IP address
1- From the WLC, ping default gateway for that VLAN
2- If the WLC can reach the gateway, its wired VLAN issue that you need to investigate in the path (maybe using wired device in the same VLAN as the clients in the switch where the APs are connected)
Now, about why the clients are not taking IP:
1- What is your DHCP, where its located? Is it the same one for all clients?
2- Do you have local APs or FlexConnect ?
3- When you run the debugs for DHCP where the process breaks?
Cheers,
Nour

WRT54G ver. 6 Connected to access point and internet, but cannot access the web

I can connect to the access point and it shows that I an connected to the internet. However when I open a bowser it says page cannot be displayed! Signal is very good to excellent. Also, I have been using it all day and it was working fine, until I shutdown. When I booted back up it stopped working. The internet is working! I have XBOX Live working right now. Just not the computer. Any Help would be appreciated.

Hi... it seems that your Wireless adapter on does get a IP address or DNS no after reboot. Try assigning a Static IP address and DNS on the Wireless Adapter. Also try to update the drivers for that wireless adapter.

Certificate between Access point and Wireless client

Hi;
is there anyway to configure a certificate between the wireless AP and clients to secure my username and the password.
my setup is WLC5508/AP1142/ACS5.4
I need the client to trust the certifcate before entering the UN/PW

Hello,
As per your query i can suggest you the following solution-
LAP authorization can be performed in two ways:
Using the Internal Authorization list on the WLC
Using the MAC address database on an AAA server
The behaviors of the LAPs differ based on the certificate used:
LAPs with SSCs—The WLC will only use the Internal Authorization list and will not forward a request to a RADIUS server for these LAPs.
LAPs with MICs—WLC can use either the Internal Authorization list configured on the WLC or use a RADIUS server to authorize the LAPs
This document discusses LAP authorization using both the Internal Authorization list and the AAA server.
For more information refer to the link-

Connection between lightweight access point and switch?

Hello everybody,
I am a bit confused about cisco 1000 series access point connection. On wireless lan controller and lightweight access point basic configuration example document id 69719 (http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080665cdf.shtml), I understood the access point has two vlans associated with (vlan 3 and 4). Am I correct?
Why is connection between access point and catalyst port just access port rather 802.1q trunk? How vlan traffic can traverse from the access point to controller?
Please advice.
Many thanks,
Nitass

Nitass,
The AP itself does not need to be a trunked port, but the uplink to the controller does. When using a Lightweight enviroment, all the traffic passes thru an encrypted LWAPP tunnel from the AP to the controller, and then gets sent out the correct VLAN interface on the controller.

Silly doubt abt access-points and bridges

hi all i have read cisco doc wherein clients connecting to access-points and also where the cisco access-point is working like a bridge and still clients can connect to it .
then any specific reason why people generally connect clients to access-points.
i mean is there any benefit of either method over the other.
any help and guidance would be really helpful.
regards
sushil

In short, it is preferred to have users connect to access points.... 99% of the time. You can use a wireless bridge (that is associated to an AP) that is connected to a switch/hub to supply network connectivity to wired users off the switch/hub. There are also access points that can be used as a bridge for building point to point connectivity.
Look at the home users with wireless.... it allows then to move from place to place (as long as there is coverage) without having to be wired in.

Need Information For Connecting Access point to WLC 4402

Hi Friends
I need Some information for Connecting my New Access point ( Cisco AIRLAP 1242AG) with WLC(4402) Controller
In our network set up we have two WLC(4402) we needs to Connect this New Accesspoint To one of our WLC
My Access point is brand New. I need to Know what all i have to do inorder to connect this AP to the controller (from Acesspoint perspective & WLC perspective)
I need to Know what I need to do in AP to connect to the Controller
Do i need to Assign Static IP Address forAP or after connecting to the switch it automatically gets ip from DHCP and regsiter with controller??
Do i Need to Configure my AP with default gateway(the switch to which is connected ?) & DO i need to configure the AP with Controller Ip address ??
Pls Assist

How do I set the transition between access points would be fine?

Hello everyone,
We have an organization Wirless controller 2504 with 20 aironet access-point (700 series)
Once I defined all the access points I noticed that the transition between them is not working fine...
I mean that clients can not walk around in our organization without having to connect to any access point separately.
How do I set the transition between access points would be fine?
Thanks a lot (:

HI Omri,
which software version you have on WLC ?
Is the site survey done propely ?
Remember: It is the client that decides when to roam and which AP to connect to based on what it perceives the signal to be.
If your site survey design is perfect and still have problems while roaming then:
Disable your lower data rates on the 2.4ghz and or 5ghz radio and your clients will roam better. Try to disable everything below 11mbps. and give that a try.May be old device will work in this case.

Can't establish wireless connection between the printer and computer.

I recently upgraded my wireless to an Apple AirPort Time Capsule. I'm able to set up the printer via USB cable. And I'm able to set up the printer on the network via the Airport WPA utility. However I cannot establish a wireless connection between the computer and the printer. When I go to the printers window in my system prefereces, there is no wireless printer available to add in the "available printers" menu. Only the USB version printer is listed and of course when I disconnect the USB cable it shows as offline.I've tried all the fixes on HP's support pages. I've tried reinstalling the printer on both the router and the computer numerous times. The only thing I haven't done is reinstall the printer using the "Install Wizard" software that is supposed to come with the printer - (mine never came with it in the first place and of course HP doesn't have it available for download). And when I reset the printer to factory settings, then connect it to the computer via the USB, there is no installation software that pops up. Cant even find the **bleep** thing in "Finder". (I'm assuming that it should show up as some sort of external device.) I've checked to make sure both computer and printer are on the same network. (sometimes my computer will grab a connection with the next nearest network.) I've checked all the settings for the printer via the HTML configuration utility. I've even updated my Macbook software and restarted it multiple times. Note: the printer actually worked for a bit when I first switched routers, but the printer's wireless function went offline several times and then quit altogether. Really frustrated that I bought another HP product thinking this time things would be different. HP is no help unless you want to pay $$ for a phone call. I'm about ready to take this thing out in the desert to use for target practice and never buy another HP product ever again.

Hi , I saw your post regarding the problems you are having with your LaserJet Pro P1102w Printer not showing on your Macintosh computer. I may have found some resources for you.
I have a few questions for you, so I can offer some additional assistance:Before you upgraded to the Apple AirPort Time Capsule, was the printer working wirelessly without any issues?
When you say; 'I reset the printer to factory settings', how where you trying to do this?
I found some instructions from this post: How do I reset my Laserjet p1102w to its defaults, copied here for you:
To restore the printer back to factory settings, turn the printer off, hold down the wireless button and the cancel button (x button) then turn the printer back on and don't release the two buttons until the printer stops making noise. (When they say turn the printer off, I think they mean unplug the power cable.)
"I've checked to make sure both computer and printer are on the same network." Do you know if you are able to access the printers Embedded Web Server (EWS)?To access the EWS - Make sure that the Ready light () is on and that the printer is idle and silent.Press and hold the Cancel button (), and release it when the Ready light () begins blinking.The configuration page prints.Type the IP address or host name of the product in the address field of a supported Web browser, and then press Enter on your keyboardLet me know if this page loads
To answer a few more items you have listed:... When I go to the printers window in my system preferences, there is no wireless printer available to add in the "available printers" menu.This could be an issue with your print system, I recommend resetting the printing system and then Repair Disk Permissions - after that try to add the printer again.
... the "Install Wizard" software that is supposed to come with the printer - (mine never came with it in the first place and of course HP doesn't have it available for download)HP provides their software/drivers to Apple to be released through your Apple software updates. You can review this document on how to Install a Mac Printer Driver Using Apple Software Update. Which leads into your next point...
... there is no installation software that pops upWhen you connect the USB cable your mac may still recognize the printer software as being already installed - check for apple updatesOn the Mac, click the Apple menu (), and then click Software Update, or click About this Mac, and then click Software Update. A list of available updates displays.
... Not seeing the printer in "Finder" From what I understand most printers will not show in Finder unless you install a memory card into a supported port on certain printer models, only then will it read it like an external device. A few more things you can check are that the new settings in the Apple AirPort Time Capsule are setup to allow the printer to communicate. There are several of these settings listed in this document; Tips and Workarounds for Common Wireless Network Printer Issues. HP regularly releases firmware updates that may also correct the problem you are experiencing. You can click on this link to Getting Printer Updates for HP LaserJet Pro P1102w Printer. I did find 2 more documents that may offer some additional information as well;HP LaserJet Pro P1102w Printer - Connecting the Printer After Changing Your Wireless NetworkAn 'Unable to Find Printer' Error Displays for the HP LaserJet Pro P1102w Printer Please let me know if any of these steps resolved your issue, or the details of what happened. I look forward to hearing from you, hopefully with good news! Thanks,

IOS 6, Netgear access point and Internet

Hi,
I’ve reached a point where I’m not entirely sure what to do next.
Here are some quick details (all are on most recent firmware unless stated):
Router: Draytek Vigor2830n
Access Point: Netgear WG102
Devices: iPhone 4, iPhone 5, iPad 2 and two iPad 2’s for comparison on iOS 5.
So, all devices running iOS 6.1.3/4 will connect to the Netgear access point just fine, can browse the LAN / stream media from network shares but internet access seems to be 'delayed' and can take anywhere between a minute to 20 minutes to connect (I give up after this). In comparison both the iPad 2’s running iOS 5 will gain internet access immediately after connecting to the access point.
On the other hand, when connecting to the routers wireless on all devices it works flawlessly and internet connection is 'instant'.
Given the problems that Netgear wifi has had with iOS 6, which were supposedly ‘fixed’ in iOS 6.1, I’m not sure what to do. It’s definitely a software problem, and could well be something to do with the router (along with connecting to the access point and iOS 6), but I’m not sure what to start changing first. iOS 5 works fine, so what has changed in iOS 6 to break it?
Its not a security issue like before 6.1 and not being able to connect to the access point at all.
Basically:
- I either need to figure what in iOS 6 is causing this ‘delay’ and how to fix it
-Give up on the access point and buy a new one (seems a bit extreme given that every other devices works fine – iOS 5, blackberry, laptops etc).
-Wait for iOS 7, hopefully in the next couple of weeks and see if it fixes it, though I can find little information on this issue as it is, and nothing to suggest iOS 7 might help. Though if iOS 5 is fine, iOS 6 broke it and 6.1 slightly fixed it, maybe iOS 7 will cure it? Doubt it…but worth waiting a few days.
Anyone got any suggestions? I have been through all the usual (HTTP proxy, forget this network, reset network settings), nothing makes it work flawlessly like iOS 5 and the issue is the same on a wide spread of devices running iOS 6.

Dont know my routerand access point works fine. Try http://support.apple.com/kb/HT4199 and make sure your setting are correct.

(Trouble printing) Trouble with connection between Macbook Pro and Hp Deskjet 1510.

Trouble with connection between Macbook Pro and Hp Deskjet 1510. (Nothing Prints).
I have a Macbook Pro and am having difficulty printing documents from ‘Pages' from my Hp Deskjet 1510. I have installed the necessary software for the printer and it is connected via USB. Every time I try to print the printer icon comes up as it should, 'printing' and then 'job completed' and then the icon disappears. (Nothing is printed.) I thought it might be something to do with Pages compatibility with the printer but exporting the document to Word or making it a PDF doesn’t change anything. I don’t have Microsoft Word on my computer. The scanner does work and when I printed a ‘Test Page’ that worked too.
Let me know if you know why this is happening.

With these settings the network now works flawlessly, however, when i have my ethernet cable plugged in, my internet access via my airport card(on the macbook pro) is no longer available. Hoping you can tell me why this would be with this info i've provided.
Educated guess. The networking devices have priorities as to which are used. The standard order is that Ethernet has a higher priority than Airport.
While your Ethernet is unplugged it is inactive and the Mac ignores it. Once you plug it in, the Mac sees that it is active and switches traffic to that interface.
I actually take advantage of this feature at home, but configuring my Airport and Ethernet with identical fixed IP addresses. Normally I'll use Airport, but if I'm copying a huge file and I want faster performance, I'll just walk my MacBook (previously iBook, previously Powerbook) over to my Ethernet switch and plug in my MacBook. Magically, the Mac detects that the Ethernet is active and continues the file transfer uninterrupted over the faster 100baseT Ethernet connection. When the transfer is finished, or if I really need to move back to the Comfy Chair, I unplug the Ethernet cable, and all activity reverts back to the Airport, all without disrupting any existing networking connections.
You on the other hand have totally different settings for your Ethernet and your Airport, so when you switch to Ethernet, you basically loose your Airport connections.
Something you can try:
System Preferences -> Network
Gear icon on the bottom left, next to the [+] [-] icons.
Select *Set Service Order...*
Now Drag the network interfaces into the perfer priority order you want. In this case put Airport above Ethernet.
NOTE: You may want to create a new Network Location for this, instead of messing with your normal home Location (which is most likely the default Automatic. That way you have your original you can always fall back to.

IPad's Roaming Between Access Points

A company with 460 Cisco Access Points is using iPad Mini's to control lighting and other things, the iPad Mini's are roaming between access points VERY SLOW, they are dropping 45-50 packets between roams. iPad 2's and iPhone's are roaming just fine, if they drop any packets it's a max of 5.
Is there any differance in the NIC's that are in iPad 2's and iPad Mini's? Or is there a setting for fast roaming?

Hi,
It seems that these APs are not aware of each other, I would suggest you look into a controller based solution, that means you need some sort of controller base AP system to get this seamless roaming feature, I also suggest you check whether there's compatibility
issue for the device with product vender.

How to test the connection between DSD backend and DSD connector

Dear all,
I am configuring the MDSD scenario .. and i want to insure that my customization is correct
How to test the connection between DSD Backend and DSD connector ??

Hi Viren,
The problem is:
We have a new BW system. The basis people asked me to check the connection between this BW system and the R/3. There is only one client for now(100). I have logged into 100 and tried executing RSA1 to check the connection, but it gave a message box saying "You can only work in Client 000". Then I have treid logging into 000(just to make sure) and tried executing RSA1. Even here I got a message saying "The SAP BW system must not be operated in client 000". Now, I am not sure of what is wrong in clien 100. I am not sure if I have to do some settings before I access RSA1 or any other BW transaction. Could you please help me in this.
Also, I just checked the RFC destinations in BW. There is a destination created for our R/3 and I have noticed that they have given a remote UserID and password for remote login. I tried to check the Remote UserID in SU01 but there is no userID with that name. Could this be a problem?
Thanks,
RPK.

Connectivity between Oracle database and client...

Hi guys,
I was asked to make a connection between oracle client and database via internet so that our clients can access the database from different parts of the country, and the data that is transmitted in the internet does not require security consideration. And I have successfully implemented this.
But later onwards they asked me to structure it in such a way so that clients must be able to select, insert, update and delete data offline, in case there is online connectivity problem.
So my question is, are there any possibilities in oracle to temporarily store data that are available in the oracle database to the client side and then later onwards transfer those datas once the clients are available online. Or are there any other alternative ways...
Additional Information - Client access the database through an application created by VB.
Please do help me on this project.
Thanks in advance for your help.

Asif.You probably should do a cost/risk analysis. Where you are headed might be able to be done (but it will require that the "clients" also have their own copy of the database) but it won't be easy and it certainly won't be cheap, either in initial implementation or in on-going maintenance. The alternative is to take a hard look at your network connections and see if it wouldn't be cheaper/easier to be able to ensure that it is reliable. Remember "the internet" won't break, it is highly redundant. If you have connectivity issues, they will almost certainly be in your own equipment and configurations, so your (your organization) will have the ability to address and fix any issues there.

Connection between 2 points in a geodetic coordinate system

In a geodetic coordinate system the connection between two points is a geodetic line or "great circle" (the shortest connection between two points on the surface of the earth).
Since Oracle 9i distances and queries like "Is a point outside or inside the polygon" are computed correctly for a geodetic coordinate system.
Even though a circle or arc is not allowed in a geodetic coordinate system (like WGS84 - SRID 8307)
arcs and circles are used in geographic applications like aeronautical maps.
Frequently a special area is defined like this "10 nautical miles around airport XXXX"
and this area is shown as a circle in aeronautical maps (in the projection).
The function SDO_UTIL.CIRCLE_POLYGON (in Oracle 10g) is very useful to construct such kind of areas and for queries like
"Does the area belonging to airport XXXX overlap with the area belonging to airport YYYY?".
For Oracle 8i we had to write special PL/SQL code.
Another type of connection between two points that is frequently used is a line of equal latitude (parallel).
Many boundaries are defined like "from meridian (longitude) 30Â°E to meridian 31Â°E along parallel 47.5Â°N".
If this line is a border of a polygon and if we use a direct connection (geodetic line) and we ask if a point is
inside or outside the polygon, we will not get the correct answer if the point is close north to this line.
We have to approximate the line and add points e.g. every 0.1Â° longitude (30.1,30.2,30.3...), then the answer will be correct.
My question:
Are there plans to support circles of equal latitude or generally rhumb lines as a type of connection between two points?
Karl Mann

There are no plans to support rhumb lines, also know as loxodromes, and including the special case of parallels of latitude, at this time. Note that it is easy to simulate such rhumb lines with a sufficiently dense set of sampled points. Such a densification is implemented implicitly for parallels in the VIEWPORT_TRANSFORM function so that the concept of the "geodetic minimum bounding rectangle" can be supported, primarily for visualization applications.

Use N95 as access point and get laptop inet throug...

Is it possible to use the N95 as an (WIFI) access point and use a laptop, a psp, an ipod touch to access the internet through 3G or even Turbo 3G?
That would be really really cool!
Regards
Raptor

I dont think it is as would have to be connected through a router to a phone line anyway. My psp doesn't even detect my N95. You would have to use it as a bluetooth modem and 3g.
Its not who i am underneath. But what i do that defines me.
