DHCP and groups AP assignments

I'm having a problem where I have AP groups works perfectly fine, but when a customer moves from one building to the other assignment DHCP from the 'first' AP group is preserved when the user accesses AP assigned to another group of AP.

For example, Laptop1 has an 10.2.1.110 address in AP Group1. When the user moves to an AP in Group 2, the Laptop1 retains the 10.2.1.110 rather than get a new address of Group2.

Traffic still works perfectly, but I need them to inherit the regimes of intellectual property of the AP group they moved (conditions of the application).

Our configuration is very similar to this document: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008073c723.shtml#configs

We have a controller 4402 with 37 1131 AP all AP is assigned to a group AP in their respective buildings and DHCP VLAN and traffic works perfectly well in each.

DHCP is offered by a Windows 2003 server as clients wired and wireless must be in the same subnet for the purposes of the application.

The controller and the AP is in native VLAN 10.

I'd appreciate any help to determine why the controller or the DHCP server is not recognize the change of the client subnet.

It is a normal behavior as long as the customer can place an AP on Group1 AP to ap on AP Group2. If you want the device to re-associate one building to another, you need to place the ap on a different WLC with a different mobility group name. If all of the ap is on the same mobility group, then you will have the seamless roaming like what you see.

  • How can I restore my tabs and groups of tabs after a update to version 36.0?

    I work with many tabs when I use Firefox. I keep classified in groups of tabs, which helps to separate the different children to work I do and interests I have. I have been using this environment for years. When I started my job today, Firefox updated to v36.0, and noted the following behaviors:

    1. There is only one group of tabs when you try to display tabs at Panorama, as opposed to a dozen groups;

    2. normally if the hidden tabs (tabs in the same group as the startup group, and not the default page) downloading of content to what the user clicks on, icon, if any, and the name of the page will show on the tab currently, the tabs display 'New tab' and no icon. It seems, however, the number of tabs that exist across all groups of tabs, but are now ghosts this default value, a group of tabs. I must add, however, I do not count the number of tabs, so I can't be exactly. When you click on it, there is just a blank page. It is so strange that Firefox knows they are there but cannot simply attach the address.

    I tried to restore the following files from my backup of Windows Home Server to the folder AppData\Roaming\Mozilla\Firefox\Profiles\ .default < gobbletygook >:

    1. in the sessionstore-backups folder, I replaced the files previous.js, recovery.bak and recovery.js (not all of the upgrade ~) with the files yesterday and the day before yesterday.

    When that did nothing, I replaced

    2 sessionCheckpoints.json

    I do not see any file with a recent date that seems to be the one that I have to restore. I should add that I don't see hidden files. I thought about the restoration of the whole of the batch, but didn't know how it would affect the program v36.0 and the profile on 35.0.1 files.

    I have deadlines this week and must immediately restore my environment in order to make these possible. I have no address list on my Web pages to work in IE or other. Any help would be much appreciated.

    On a second note, I had been wondering recently if this tab group environment is an appropriate way to maintain my work environment. Sometimes, during the opening of Panorama, I would get an error saying a script takes too much time, but if I clicked on continue, it would display the groups in a few seconds. I considered bringing it in bookmarks, but it would be tedious and more difficult to access and open several tabs. Initially, I tried tabs groups thinking it was just a matter of maintaining a table of addresses (in tabs) with a name or an ID of tab group. How that might go wrong? Well, there, so it is obviously more complicated than that, and I did not know that upgrades would affect the data of a personal nature. That I should abandon the use of tab groups?

    With the help of information from the user, ptressel, in a post here on the existence of sessionstore.js when version 33 was released, I could easily get my tabs and groups of tabs as follows:

    1. close Firefox and, perhaps, wait a few seconds (30 years?) for any final closing of files;
    2. Check if you have a sessionstore.js file in your profile folder, named as I documented in my original post above.
    3. If this is not timestamped before the discovery of your problem, open the sessionstore-backups folder.
    4. Check if the recovery.js file is properly stamped and, if not, the recovery.bak.
    5. At this point, you are likely to find that none of them is before your problem occurring. If so, open your backups from this folder and go through steps 2 to 4 to find a file before your problem occurring.
    6. When you find a file, copy it to the root of your current profile folder and name it, "sessionstore.js.
    7. Open Firefox. Mine opened upwards as you wish.

    It is a solution for Windows. Sorry I can't comment on other platforms, but I'd bet it's just a copy of file and change of name, it is likely even.

    For Windows users, you can find you must sign out and sign in as administrator in order to access backups. You must not logoff your standard account, but do have Firefox closed as described above.

    Hope that helps.

  • Is it possible to save the current tabs and groups so that they can be recharged at any time?

    My Firefox crashes sometimes, and when I start it up again, my groups and tabs that I had are lost, so I need to recreate my history window. Is there a way I can save the groups that I have with the tabs on the inside so that I can retrieve them at a later date.
    "I say that Firefox does not save the whenever I close the browser, so I'm güssing there a file somewhere that contains this information, if I know how is called this file I could save it on my regular schedule and retrieve them if I had to, of course the best solution would be to have a ' save the groups ' & 'Support groups' in the menu.

    Thanks in advance

    (PIN) App tabs and groups of tabs (Panorama) are stored in session data in the sessionstore.js file in the Firefox profile folder.

  • Research Protect deleted all my tabs and groups of Firefox

    I had about 200 tabs grouped together in about 30 groups of 31.0 Firefox (latest version). The Group appeared when I clicked on the icon to the left of the button "minimize" or press CTRL + SHIFT + E. It is called "your Firefox tabs - group". I also use Xmarks, but I have disabled Synchronization tab recently.

    Generally all the tabs and their groups have been saved when I closed Firefox. Today I opened Firefox and all tabs and groups disappeared! Instead, it opens some search engine called Trovi (www.trovi.com) with "bing results. Its the same in Chrome, Opera and IE.

    My OS is Windows 8.1 update 1 with all updates installed. My antivirus is Avast! with all updates installed. There was some malware installed of course, but I'm not awake me. I ran a 'full system test' in Avast! latest updates, which is the deeper analysis that I know (without my laptop HP ProBook 4730 s restaring). No viruses were found.

    I'm suspecting a program called 'Research Protect' version 2.16.10.61 'Client Connect Ltd. It was installed with PowerISO 6.0 x 64.

    I tried to run the system restore, but it seems that all the restore points I ever created are now deleted! I discovered this by opening the system properties-> system-> system restore Protection. However, 'Protection' is 'On' for my system disk.

    How can I restore my tabs and groups? It is extremely important for me.

    Accidentally, I posted my question twice - my apologies. I marked this as resolved and will continue to ask for help on the other.

  • command and group numbers

    Hello

    I have a number of lines where each shows a quantity (in a single column) with a length of wood (in another column), say...

    3 4500

    2 3000

    1 6000

    9 3000

    1 4500

    is there a formula where I can create two additional columns with the sum total of all the required lengths? so, something like this...

    11 3000

    4 4500

    1 6000

    the order of length?

    also, it will not be fixed lengths, so ideally my formula will order and group some lengths come in the columns.

    hope that makes since, cheers, ric

    I think I could to make it simpler, in my second list "lengths", list all possible, according to the digital agenda, such as 3000, 3200, 3600, etc. 3800.

    in this case, I'm sure that there is a simple way to add the amount of items (in the first column of the first series) each time the length is displayed in the second column (in the first game)...? !

  • tabs and groups of tabs are lost

    Closing Firefox and then restarting him, invariably all my tab groups seem to have lost their legs. Reopening of groups of Eve extended or closed (using the Group Manager add-on tab) will not help.

    It is not happened on my previous install but have since upgraded to Kubuntu 14.04 and Firefox 29 (to be precise Firefox to canonical 1.0), I keep losing my tabs and groups of tabs.

    Don't know what mistake I make.

    In case you use "clear history of Firefox closing:

    • do not erase browsing history

    Note that compensation "Preferences of Site" clears all exceptions for cookies, images, pop-up windows, installation of software, passwords, and other specific data from Web site.

    You can check for problems with the sessionstore.js and sessionstore.bak files in the profile folder of Firefox that store session data.

    Rename (or delete) the sessionstore.js file and possible sessionstore-# .js files with a number and sessionstore.bak in the Firefox profile folder.

    Delete sessionstore.js will cause App Tabs and groups of tabs open and closed tabs (back) to get lost and you will have to re-create them (take note or bookmarks if possible).

  • Time Capsule do not pick up address DHCP and cable modem...

    You just bought a Time Capsule and a couple of Airport Express. If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

    That being said, I tried to create a mobile network instead of pure wi - fi and am studying various behaviors that are not as expected when I rear hub to the Internet Time Capsule, but need to isolate and go 1 bit at a time... (it works not as well as suggest Apple instructions on homelessness of installation)...

    If:

    1. configuration of the modem cable shows that DHCP is 'ON' and supplied address range 192.168.0.x by 192.168.0.y,.

    2 Cable modem wireless is disabled,

    3 Time Capsule Wan is connected to the cable modem, Ethernet

    4 Time Capsule is configured to request its address IP, DHCP

    5. Airport Express is in Bridge mode and have addresses such as 10.x.y.z (appears to be from a Time capsule).

    6. safe as Time Capsule is set to be as DHCP and NAT

    7. There is NO other device in this configuration connected by Ethernet except the cable Modem and the Time Capsule.

    So, why is the IP address of the time Capsule 76.181.45.xyz? (The address is NOT in the range of the DHCP as described in the #1; it is not supposed to be?) ....

    Whence this address?

    A friend says this address puts the "other side" Time Capsule of the cable Modem, directly on the Net?... (Shouldn't worry?) ....

    If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

    It's because you didn't have the devices connected via Ethernet before you set up the. Given that the installation utility saw a wireless connection, it is assumed that this was the way that you want to connect devices on your network at all times... so he put it this way.

    If you had an established connection Ethernet before you ran the installer, then the utility would have detected this connection and set up the airport to "expand using Ethernet", does not extend to assistance of wireless.

    (it works not as well as suggest Apple instructions on homelessness of installation)...

    If all goes well, you don't talk about this document... Wi - Fi base stations: extend the reach of your network wireless by adding additional base stations Wi - Fi - Apple Suppo... .. Since the 'how' information in this article is at least 4 years late, bear little resemblance to the latest version of AirPort Utility and some of the information are simply not true.  This document if trash is what you... He'll probably do more harm than good with regard to the details of setting.  The article is OK for basic general information, however.

    6. safe as Time Capsule is set to be as DHCP and NAT

    It should not be if your modem is a modem/router "" or type 'bridge' of the device which is also DHCP and NAT services. The fact that you have disabled the wireless on the device confirms that it is both a modem AND a router. That being the case, then you have two devices that both struggling among themselves to try to control the same network... AND do you also have a network error called Double NAT... something you don't want.

    Probably the best at everything again and provide us with the number of brand and model of your "modem", that we can confirm what it is that you have, then the correctly configured time Capsule to work with this device. Once the time Capsule is set up correctly, it will be easy to put in place the other airports.

    I put t know what are the causes of the problem too but did you look in Event Viewer? Sometimes, it's really useful.
