Controller vs. Cloud-based (cloud controller)
We are trying to navigate the waters in choosing between a in-house, controller-based, wireless network solution or a cloud-based solution. We have been presented with the usual suspects in cloud-based (Aerohive, Meracki, etc) and with Cisco (5500) and Aruba on the other side. We are a multi-campus organization with approx. 200 APs.
Any hard reasons why go with a controller-based vs. cloud-based solution? If we must keep the conversation limited to Cisco, why go Meracki over Cisco's WLC solutions or vise versa?
For the project I am working on the Meracki solution has the following disadvantages:
- The client has a strict secuirty policy that prevents the off-shoring of any data.
- Our standard SmartNet maintenance contract includes the on-site replacement of faulty equipment. It appears that Meracki does not offer this option.
- I am based in the Southern Hemisphere. I found no Customer deployment stories on the web site for this region, only for US and European locations. Not sure therefore if they are shipping to countries in this region yet.
- The web site talks about how software is automatically updated on WAPs. I would require more information as to how this is scheduled so as to minimise downtime.
Advantages of Meracki
- Meracki is owned by Cisco.
- Where I live skilled wireless engineers are in short supply. At face value it appears with the Meracki solution you could hire more junior wireless engineers.
- The 99.99% SLA is attractive.

Wireless Management - Local Controller vs. Cloud
Good afternoon,
We are currently looking to upgrade (re-design) our wireless network at our college.
I was curious if anyone had any experience going from a local, controller-based wireless network to a cloud-based controller? If so, what have you found the pros and cons to be?
If you thought about going to a “cloud solution”, what stopped you?
In addition, any other feedback on Meracki, Aerohive, Aruba, or other solutions would be much appreciated.
About Us
We are currently running wireless at our 3 primary campus locations, and looking to add it to our 3 satellite locations.
We use 4402 WLCs at our primary locations with a mix of 1140 and 1240 APs.The advantage of using local controller are
1.Lower Operational Expenses
2.Easier Way to Scale with Optimal Design
3.Single Location to Apply Wired and Wireless Services
In addition, certain controllers, such as Cisco Wireless Services Module (WiSM) blades on the Cisco Catalyst® 6500 Series Switches, perform various other functions, including application inspection using the Cisco Network Analysis Module, enhanced security with a full stateful firewall and intrusion detection system, and more. Placing the controller in a centralized location simplifies N+1 or N+N redundancy, depending on the size of the network. This redundancy means that for each wireless controller (N) there is at least one backup controller (+1). The backup controller is not positioned to actively contribute to normal system operation but provides a reliable way to protect the network in case of any failure or downtime on the component being used to manage network access
The advatage of using cloud based controller
1.The Cisco Flex 7500 Series Cloud Controllers are used for this.
2.you can consolidate multiple controllers in to one controller with support up to 6000 access points and 64,000 clients from data center
3.Gain significant saving in operatins by configuring , managing and troubleshooting 6000 AP's and 64,000 clients in single pint of touch
4. When traffic is directed to the controller in FlexConnect Central switched mode, the Flex7500 Series supports Application Visibility and Control (AVC). AVC includes the NBAR-2 engine, Cisco's deep packet inspection (DPI) capability that classifies applications, applies quality of service (QoS) to either drop or mark the traffic, and prioritizes business-critical applications in the network. AVC uses NetFlow Version 9 to export the flows. The Cisco Flex 7500 Series in central switched mode also supports Bonjour Services Directory to enable Bonjour Services to be advertised and utilized in a separate Layer 3 -
App Controller and Clouds connect to or configure public/private clouds
Hi
i was wondering what kinds of clouds private/public can App Controller can connect to or configure and where can i find the list of the public/private clouds that it supports.
ThanksApp Controller can connect to the following clouds:
System Center Virtual Machine Manager
Windows Azure
Hosting service providers
I don't have a list of the Hosting service providers that have a compatible cloud, although I know a couple have previously posted to this forum. The service provider needs to be running System Center and in particular
Service Provider Foundation.

SSO with Hybrid Cloud-Based Deployments
Hi
I´m wondering, how SSO works with Hybrid Cloud-Based Deployments.
I want to use Jabber for Windows with WebEx Connect and Unified Communications integration with Cisco WebEx.
Questions:
How can I configure Jabber for Windows to use SSO with WebEx Connect after Client-Installation?
I´ve read, that SSO username with WebEx Connect will be [email protected] Correct?
I´ve read, that I have to create a jabber-config.xml with a follows to enforce Jabber for Windows to use the Webex-Connect login credentials also for Phone Services. Correct?
<CUCM> <PhoneService_UseCredentialsFrom>presence</PhoneService_UseCredentialsFrom> </CUCM>
If this is correct, Jabber for Windows will use [email protected] to authenticate with CUCM, but CUCM would need only the username without the domain. From my point of view, Jabber for Windows will not be able to authenticate with CUCM for Phone Services.
Any thoughts?
thank you
TinoHi Maqsood
Thanks for your info. I´ve tested the "PhoneService_UseCredentialsFrom" attribute in my hybrid deployment and it seems, that it effects the jabber also in this scenario: the credentials form in the jabber options menu are not displayed.
My understanding of the admin guide is, that it should work:
Authentication in Hybrid Cloud-Based Deployments
If the client authentication credentials are the same as the voicemail service credentials on Cisco Unity Connection, you can specify the VoicemailService_UseCredentialsFrom parameter in the Cisco Jabber for Windowsconfiguration file. This parameter uses the client authentication credentials to access voicemail services. As a result, Cisco Jabber for Windows users do not need to enter their credentials for voicemail services in the client.
You should ensure that the sign in credentials and voicemail service credentials are the same for the Cisco Jabber for Windows users. If you set this parameter, the Voicemail section is not available on the Phone accounts tab in the Options window.
thanks,

Creative Cloud just wasn't working for me, so after several years of frustration with being abroad and not online when the program decided to require online verification, I'm ditching Creative Cloud and reverting to the purchased Adobe Acrobat XI Pro point product. However, after uninstalling Creative Cloud Desktop (and CC-based Acrobat XI Pro), it still wants to go online and check my CC subscription, disallowing use of the newly installed point product version from a several year-old ESD file (and the more recent AcrobatUpd11010.dmg file).
Anyone have an idea of how to eliminate request to renew my subscription?
If, as a journalist, I've have these issues over the past two years, including this final insult when I'm trying to get away from CC, it can't be a one-off problem. So I'd like to hear details about others who've had a similar issue with reverting from CC back to a point product or to CS.
Thanks,

How do I create a UDL for a Cloud-based Database like Amazon ?
I have been using UDL connections to SQL Server without any issues.
I was just asked to look in to Cloud-based databases, but I'm not sure ho to create a connection to the databases once they have been created.
Has anyone done anything like this?
If so, do you have an example the you can share?
KeithUnless the cloud based database you are interested in does provide an ODBC and/or OLE/ADO driver there is no way to connect to this database through the LabVIEW Database Toolkit or any other of the Database Toolkits out there that can use an UDL.
However if you talk specifically about a service like Amazon RDS then this is based on a database engine of MySQL, SQL Server, Oracle SQL or PostgreSQL depending what the client chose when setting up the DB in the Amazon cloud and as such you simply would have to use the according database driver and get the correct internet address to connect to. What address that would need to be should be most likely visible in the setup console program or as Amazon calls it the AWS Management Console.

Hi @Sunshyn2005
I timed-out waiting for advice, and contacted HP Support, who helped me get the printer back on the air. While we didn't manage to root-cause it, in the course of trying various things, the tech disabled Norton 360's firewall, which then allowed connecting to the printer, and restoring print service, which remains up after re-enabling the firewall.
The timing of the disconnection doesn't neatly corellate with any Windows updates. My own theory is that it was caused by a 360 update, but am unable to find a smoking gun, since 360 doesn't provide update history. The exact root-cause remains a mystery, but at least provides another thing for folks to try should they find themselves in similar straits.
I really appreciated your hint that a Windows update might be the root cause, and your pointing out how to review the history and back-out updates: this morning, I found that Windows had installed a batch of updates overnight, and found that no browsers worked. Using your advice, I rolled back the update, restoring browsing.
Thanks,

I used a friends mac to initiated a adobe premier pro project on a mac drive. I then saved the project. I uploaded the saved project to my Cloud. On my Windows based laptop, I signed into my Cloud account, downloaded the same project. I opened my Pr app, and could not see the project, though the parent file is openable and searchable. Have I not used the full ability of cloud, meaning have I incorrectly synched something? Any help would be appreciated, thank you!

I already have an app that I paid someone to make but I needed to make some changes to the code and wanted to do it in Dreamweaver. How is it best to load my code into Dreamweaver, navigate through it, and find the code I need to change? As well my version of Dreamweaver ( It the new Cloud based ) doesn't have any of the App features. Do I need to load it differently or something?
It really depends on how the app was developed and loaded. DW can help with web interfaces and some parts of the app development, but depending on the complexity and language of the app you may need additional tools like Xcode (Apple) in order to modify the app.

Remote upload into sharepoint 2013 document library (cloud based)
We have a sharepoint 2013 in the cloud.
Is it possible to have some kind of service (windows or web based) that can access a document library on said cloud server and put files into said document library?
I don't think we have a lot of behind the scenes access to the cloud instance of 2013.Hi,
As I said above, we could use the Client Object Model to upload the files without the user having to go to SharePoint in the browser first and logging in.
We can use the credentials in the code as below, the code would copy files to SharePoint online, it worked well in my environment, you can check whether it works.
public static void CopyDocuments(string srcUrl, string srcLibrary, string destUrl, string destLibrary)
// set up the src client
ClientContext srcContext = new ClientContext(srcUrl);
SecureString passWord1 = new SecureString();
foreach (char c in "Password01!".ToCharArray()) passWord1.AppendChar(c);
srcContext.Credentials = new SharePointOnlineCredentials("[email protected]", passWord1);
Web srcWeb = srcContext.Web;
List srcList = srcWeb.Lists.GetByTitle(srcLibrary);
ListItemCollection itemColl = srcList.GetItems(new CamlQuery());
srcContext.Load(itemColl);
srcContext.ExecuteQuery();
// set up the destination context
ClientContext destContext = new ClientContext(destUrl);
SecureString passWord = new SecureString();
foreach (char c in "Password01!".ToCharArray()) passWord.AppendChar(c);
destContext.Credentials = new SharePointOnlineCredentials("[email protected]", passWord);
// get the destination list
Web destWeb = destContext.Web;
destContext.Load(destWeb);
destContext.ExecuteQuery();
foreach (var doc in itemColl)
try
//if (doc.FileSystemObjectType == FileSystemObjectType.File) //Field or Property "FileAttachement not found."
// get the file
File file = doc.File;
srcContext.Load(file);
srcContext.ExecuteQuery();
// build destination url
string nLocation = destWeb.ServerRelativeUrl.TrimEnd('/') + "/" + destLibrary.Replace(" ", "") + "/" + file.Name;
// read the file, copy the content to new file at new location
FileInformation fileInfo = File.OpenBinaryDirect(srcContext, file.ServerRelativeUrl);
File.SaveBinaryDirect(destContext, nLocation, fileInfo.Stream, true);

ACL on controller-based wireless
We're trying to put an ACL on our wireless guest subnets on a controller-based wireless system. We're using 2 of the WiSMs. The ACL I used to use in WLSM allowed the guest subnet to the dhcp servers and out to the internet and dropped everything else, but I don't know where I would apply that list now for it to work with all the different vlans and addresses for the WiSMs.
Hi Brian,
Perhaps this doc will help;

Hi Group:
I am developing a measurement and control system based on the PCI-6040E and SCXI1001,1102, and 1160.
But now, I have a question ,which is how to implement a controller in main_vi based on the test data of sub_vi.
my program is consist of main_vi and several sub_vi, the main_vi is used for controlling and give the operation signal to hardware system (relay). and sub_vi is used for sampling data.
for example: the sub_vi collects data from the hardware and the control algorithm and output is implemented in the main_vi, so the question is how to transfer the test data from the sub_vi to main_vi synchronously.
I try to set the output connecter, but the data just return when sub_vi is closed.
anybody have good idea about it.
Thanks a lotHi hanwei,
I'm making the assumption that you are not using LabVIEW Real-Time. If you are, you should use RT FIFOs. Otherwise, follow MikeS81's advice.
I would go a step further and say that most likely it would be a better design to remove the loop (while loop?) from the subVI and instead place the subVI within a while loop in your top-level VI. This way on each execution of your subVI it will quickly return your data. Then you can also perform all the queue and dequeue operations in the two seperate while loops in your top-level VI. This organization will be easier to read, document, and understand.

Firefox requires clicking "Allow" to view one screen in cloud-based database
When using Firefox (but not Windows) in a cloud-based database (SaaS) for facility scheduling, one particular screen (in a series of screens needed for each reservation) will not load until I click the "Allow" button every time. This is enough of a nuisance that I want to tell Firefox to trust everything on the url, my.serviceu.com/. I'd like to know how to do this. I only have this problem when using the system on Firefox, not MS Explorer, but the system is written to run best on Firefox.
Do you mean this?
*Firefox > Options/Preferences > Advanced > General Accessibility [ ] "Warn me when web sites try to redirect or reload the page"
The setting in "Options > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.
