RF-group WLC4400

Hello

I have 2 WLC 4402 which I configured in the same group of RF. What I see, is, from the windows to AUTO-RF, on the side, I don't see that a single controller.

Each controller is the "group leader".

The controller are connected to the same local network and can ping themselves.

Any help?

A big thank you and best regards

Luigi

Hi Luigi,

Before you can configure really RF grouping each WLC must have at least an access point installed that can hear another point of access that is associated with the other WLC;

In view of all the controllers share the same name of RF group, to form a group of RF, a WLC needs to have only a single access point to hear a point of access to an another WLC

Workflow involved when a system of MRR works to form a grouping RF. It is also imperative to understand where RF calculations occur. This is a preview of what the Solution of Cisco Unified through to familiarize themselves, group and calculate all MRR features:

Controllers, including APs should have a calculated RF configuration as a single group, are provisioned with the same name of RF group. A RF group name is an ASCII string, each access point uses to determine if the other APs they hear are part of the same system.

APs send periodically messages from neighbor who share information about themselves, their controllers and their RF band name. These neighbouring messages can be authenticated by other APs that share the same name of RF group.

APs that can hear the messages of these neighbor and authenticate messages based on the name of Group shared RF, share this information with their connected controllers. Neighbor messages consist mainly of controller IP addresses and information about the AP that transmits the message.

The controllers, who can now identify the other controllers that are part of the RF group, form a logical group to share information of RF. Subsequently, the controllers elect a group leader.

Equipped with detailed information on the RF for each AP environment in RF group, a series of algorithms of MRR are executed at the head of RF group. The algorithms are designed to optimize the AP configurations associated with these functions (with the exception of the cover hole detection and the Correction algorithm, which are executed on the local APs controller):

Of the channels of the dynamics (DCA)

Transmit power control (TPC)

The good doc.

    When I send a mass text by enabling / disabling message group, then I turn on message group, suddenly became a group text responses?

    I sometimes send jokes or notifications to multiple contacts.  After I mass text them by activating / deactivating iMessage and Group Messages, then I switch on iMessage and Group Messages - will people I sent a mass text message can see phone numbers and the responses of the other?

    I think it should not because after sending the text it comes just up on their phone as a text message you only, but I want to just make sure

    Thank you

    Hello Eddie7777,

    Thanks for your post. I understand that you wanted to confirm if a mass message will convert to a group message after activating again Group Messaging. I certainly understand wanting to send a mass text message without launching a group of crazy message where number of all is shared. I'll be more than happy to help clarify.

    I tested on my iPhone, and so my previous knowledge on the messages, I discovered some great information. When you send a mass text with disabled group messaging message, it sends the messages individually and these other people only get a text without your mass SMS numbers. When you have enabled messaging group once again, it won't change the message on their end, and if they say it will for you.

    Hope this helps explain things!

    Take care!

  • iMessages group Conversation does not go in DND

    I've just updated to iOS 10 on my iPhone more than 6 and a group conversation in the Messages that I sometimes put on DND now does not recognize that the conversation has been implemented within DND.  Messages continues to inform me about all messages from anyone in the group.  Is there any solution for this?

    Thank you

    Brent

    Have what troubleshooting you tried? Troubleshooting user steps include reboot, reset, restore from backup, restore to factory; tests after each stage.

    If you return in the message after the ignition of the DND, does always show as it is turned on?

  • I restored my iPhone 6 from an itunes backup, but my group chat contacts are changed

    So I backed up my iphone on itunes because I went to the apple store to solve a problem I had. After that that they had deleted everything on my phone, I went home and tried to restore it. All went well, all my contacts were saved, my pictures, etc. so I waited so he could complete the synchronization for my laptop. While I was checking my messages, I noticed that many of the cats from group I had, had shared some of my names of friends with other people on my contact list. I also saw that other people who were in the GM had their photo ID, but instead of their name, their phone numbers were posted. I rebooted my phone and hope so that it can be corrected, but it didn't, I also tried to add the people who did not appear in the newsgroup, but I have added to them, the person that they have been replaced by a show! If anyone can help me on how to solve this problem, it would be highly appreciated!

    Hello, arsmars!

    Thank you for using communities of Apple Support. Looks like your Contacts are not being very cooperative since you have restored your iPhone iOS 10 6. I know that I have not memorized a phone number in ages and would need this support as soon as possible. I'll be happy to help you.

    It seems that you use iCloud to synchronize contacts between devices. On your iPhone, go to settings > iCloud. Disable the Contacts, wait 5 seconds, then turn it back on and check your Messages and Contacts.  I have a link below if you are still having problems:

  • IOS 10 Notifications: Please bring back ability to group by app notifications

    Please, please, please bring back the ability to group by app notifications...

    And why Apple consider it an improvement "," to take away our ability to choose how we sort our notifications in the first place? Not happy at all to this subject :-(. Some of us are _a_lot_ notifications, and also be able to group by app notifications means that we can then _clear_ notifications by app, as well (i.e. clear specific _types_ of the notifications at a time), which is VERY useful... With respect, this is a gross oversight on the part of Apple. I'm an ardent loyal fan, very long Apple products, but 'small', absurd decisions like this add up, making it more difficult and more difficult to justify is not something else.

  • iOS 10 - auto bluetooth with contact group synchronization

    I have my iPhone 5s coupled to my car bluetooth hands-free system.

    With iOS 9 I was able to sync only certain groups of Contacts from iPhone. It was helpful that I have a number of groups in iPhone Contacts, including one specially created for syncing to my car.

    Since the update of my iPhone to iOS 10, I have that option in the bluetooth settings of the iPhone to check any combination of 'Favorite phone', "Phone Recents" or "All Contacts". None of them are useful for me as I want to synchronize with one of the original groups in Contacts.

    Help, please!

    Thank you.

    The same problem. A month ago I could synchronize specific groups with the phone book from my car. Now, the only option is "Contact".  Help!

    I do my job to the computer on a MAC book PRO. I want to create a document using Pages and then convert the document to PDF and send a group email. I want to send the PDF using the pdf for each receiver icon must click the icon to open the document. My problem is the document does not show the icon, but rather the document is already open. I spoke with 2 Apple. 'Experts' care and can help me. Can someone tell me what to do?

    It's a question of how the recipients e-mail programs deal with attachments. Many e-mail programs will open all the files they can handle, including files jpg and PDF, by default, and if the recipient has not changed that there is nothing you can do about it. The only solution is to the compress first, then it will be delivered as an attachment, allowing the recipient to decompress and open it.

  • I can't see Group Conversations?

    My phone number has recently added 2 cats of Imessages group. For one of them, I personally entered the phone number. However, on my Iphone I can't see group conversations. I can't see any discussion group click on everything. I have group messages and MMS on. Also, I tried to reset the network settings, restart my Iphone and turn on/off Imessages. I currently have 9 Ios. Everyone in the group the cats have been the reception and sending of the messages that I don't know. Is there a solution?

    This article can help:

    Send a message from your iPhone, iPad or iPod touch - Apple Support Group

    To quote a few excerpts: If you send a message to group of people who don't use an iMessage, the message is sent as an MMS or SMS message.  Messages MMS & SMS groups appear in green text bubbles and go through your carrier instead of Apple. In addition, when you send an SMS to group, all responses are sent as individual text messages and recipients cannot see the other answers in the group.

    So, if you are having problems with Group SMS and MMS messages, I think you will need to contact your support provider.

  • Contacts - assign group on import

    When the Yahoo address book importing (exported as a CSV file) is it possible during import the corresponding field to assign the category (the label of Yahoo) as a group?

    The idea is to bring in a few thousand emails, who have 10 groups of different sizes.

    I know that I can a) affect the other field label or Notes and then later b) search maps for names of previous groups, c) select all and then d) create each group. I hope that I can eliminate these steps.

    You could probably do with some AppleScript, but otherwise I don't think.

    I think that the simplest solution would be to divide the file into groups and import each separately. When you import, they all appear in the last Smart import group. You can then create your new group and drag them all since the last import in the new group.
