Impossible to get trunk port to work on 4402 and 6509

I'm having a problem getting circuits developed on a pair of 4402 I just expdis preconfigured.

The switches are running Catos.

I've tried both using a SHIFT and individual ports on the WLC, and the only way I can access the WLC is when the switch port is configured as an access port.

Whenever I have change the link mode on, I lose access.

I tried to restart it and that didn't work either.

The subnet manager and ap - manager is in vlan 254, and I put the vlan native of the switch ports to VLANs 254.

I tried all forms of the sheath (desirable, nonegotiate etc.), but I just will not work.

I use this exact set elsewhere without any problems.

Controller was originally on 4.2.130 and is now on 5.1.150.

Someone has an idea or two?

Very well. First make sure that the wlc which management Manager and thus lies on the same vlan. Also, make sure that it is not signposted in the wlc which means that it is set to '0 '. On the trunk dot1q, assign it vlan native what the wlc is configured for. Make sure that you do not have the global command "tag dot1q vlan native. Also male that the service port has an ip address and not routable in your network.

  • Get two licenses that work on Mac and PC.

    Hello

    I am a student who was hired by a company to make more videos explaining what they do as a society and how it's done. We would like to buy Adobe Premiere Pro CS6 and use it to create videos. My employer uses a Mac and I use a PC. I'll do some work from home and at the office as well. We would like to know if there was a way to buy Adobe Premiere Pro CS6 with two licenses that can be downloaded on two separate computers, one on a PC and the other on a Mac.

    Thank you

    Jesse Scholz

    If you purchase two licenses, one for a windows machine and one for an apple machine, then you should have no problem with installation on two machines, a windows machine and the other an Apple machine, respectively.  The two licenses would essentially purchases separate.

    A single user license allows installation and activation on both machines (from the same platform), so you could actually install the windows on two windows machines and licenses from apple on two computers from apple.  What you can't do, is buy a license and use for a windows machine and an apple computer.

    If you want to save money and make only a purchase...  If you were to purchase a single user subscription creative cloud, you can use the same subscription to install on two different platforms.  The only question would then become the following condition in which you can use only one of the two facilities at any given time.  But if you want to be the only one using the machines that don't need not be a problem.

  • Impossible to get NIC teaming to work

    I'm a total noob in networking so excuse me in advance.

    I'm setting up a virtual environment with 3 hosts ESXi 6.0 that all with 2 physical network connected to a single Catalyst 3560 switch cards. I have 4 VLANS to shared resources on a port channel and have the 2-way switch NIC assigned to this channel. I can't get ping half of the time, if I have two active network cards and I can't do more than 1 virtual machine by host to ping the host. Here is the config on the switch for a host:

    Interface Port-Channel 4

    Test host 3 Port Channel description

    switchport trunk encapsulation dot1q

    switchport trunk allowed vlan 2,5,102,104

    What I've done the research tells me that I have everything configured properly. Y at - it still system requirements within the switch or ESXi 6.0 to enable LACP on this channel port? Any help would be appreciated!

    Hello

    As others have said, it looks like your team / config is wrong - see http://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-60-networking-guide.pdf

  • Impossible to get a javasript alert work in FF, but the same alert works in Internet Explorer, Chrome, Opera.

  • Impossible to get Graph.DataSource to work in WPF, I (thread question?)

    My chart is work beautifly when I use:

    chartCollection.Append (measure. GHz, measurement.dB);

    But when I try to use this call to the same method, I get nothing on the graph:

    Double data = new double [256];
    ....
    Graph DataSource = data;

    I know not if there is a suspicion, but I declare chartCollection on the main thread, and then pass it on to a different thread to collect data and it draw in real time.

    I could have lived with chartCollection.Append but in this case, I got a lot of data instanteneusly and I want to assign to chart at a time.

    Moreover, it seems that you need about 350 ms differ between each card. Add to not cause exception... but in my case I need to delay in all cases (for data) is not a problem.

    Thank you!

    I'm not very clear on how you mix the table/matrix updates. Here is an example of chart queue adds via the dispatcher (using a class task and assistance as a quick way to simulate the substantive work). You can use any delegate with the dispatcher, so you can assign DataSource in a delegate instead of use the method append on a collection of table.

    public partial class MainWindow : Window {
            private readonly ChartCollection chart = new ChartCollection( );

    public MainWindow( ) {
                InitializeComponent( );

    this.graph.DataSource = chart;

    var worker = new Worker( this.Dispatcher, chart.Append );
                Task.Factory.StartNew( worker.DoWork );
            }

    private class Worker {
                private readonly Dispatcher dispatcher;
                private readonly Action append;

    public Worker( Dispatcher dispatcher, Action append ) {
                    this.dispatcher = dispatcher;
                    this.append = append;
                }

    public void DoWork( ) {
                    for( int i = 0; i <= 360;="" ++i="" )="">
                        double value = Math.Sin( i * Math.PI / 180 );
                        this.dispatcher.BeginInvoke( this.append, i, value );
                        Thread.Sleep( 100 );
                    }
                }
            }

  • Error code 8E5E0147, impossible to get Windows Update to work

    When I try to download windows updates I get the following error code: "8e5e0147" and none of the updates will be installed. I now like 15 important updates.

    I already searched this forum and other forums of solutions, but none of those I've tried seems to fix the problem. That's what I tried:

    • Disabled Antivirus and firewall software
    • Tried to install updates and
    • Manually install the updates by microsoft download. This give me an error code, just "failed to install".
    • Run a checkdisk, no errors.

  • Impossible to get WRT300N/Atheros AR5009 working draft-N

    My HP laptop with Vista Home Premium is an Atheros AR5009, which is supposed to work with draft-N card.  Unfortunately, I can't get my WRT300N and the AR5009 to connect to any better than g speeds.  I tried first to specify the router to run only at the draft-N, then the laptop couldn't connect.  I tried to find an option for the adapter work on the project-N only, but failed.  I read a few forums where they said that the problem was that WPA2 security must be used, so I mounted that - no change.  HP of not responding on their end, so I hope that someone else had my problem and can offer a solution.

    Nevermind, I managed to solve the problem on my own.  The router and the wireless card must be set to WPA (not WPA2) encryption.  Strange, but it works.

    I can't Google earth to work after downloading Google earth, when I try to use it I get a message that Google Earth has stopped working. Is there a way to tell if my graphics card works or if I need a new graphics card?

    As far as I know, these are the requirements for Google Earth - https://support.google.com/earth/answer/20701?hl=en. Make sure that your PC and graphics are satisfied, and that your graphics card drivers are up to date with the latest version of your PC manufacturer supports the web site.

    - Https://support.google.com/earth/answer/176180?hl=en may be useful. Try what he refers to as switching between DirectX and OpenGL to see if that helps etc..

    Is there any (exact) error message and the error code given? There are clues that are recorded in the Event Viewer log? (look in "Local event viewer" - "summary of administrative events' - 'Criticism' or 'Mistakes' for any reference to the time and date of the accident).
