The CoS class system / host-complete control

Let's say that the UCS system QoS enabled priorities:

-Platinum, CS5, 30%, without moving

-Bronze, CS2, 20%

-Best Effort, everything, N/A%

If a QoS of UCS, called 'MostlyBronze' policy is configured with "priority: Bronze" and "host controls: None", then any traffic received on one VMnic associated politics MostlyBronze (CS0, CS2... whatever) will be stamped with CS2 and queued using weight Bronze 20% as defined in the system of QoS class.

But what happens if "host controls: Full" is checked in the MostlyBronze policy?  Are received on a VMnic MostlyBronze packages that are unmarked (CS0), always full of CS2 and given the weight of 20% queue?  Or is the 'reliable' CS0, and packets are treated as best Effort?

Similarly, if ' host controls: Full "is checked and that the received packet is marked CS5, is he queued as Bronze (20% by weight, activate the drop), but passed with unchanged CS5?  Or is the marking of CS5 received "in confidence" and he is awaiting Platinum (without moving), although the vmnic is associated with the MostlyBronze policy?

Hello

If the host control is set to FULL we don't mark frames with QoS settings configured from UCSM, we base CoS marking out of the BONE. Just so you're aware CS0 = best effort in UCS.

Does that answer your question?

Thank you

Justin

  • VMPlayer newbie - switch back and forth between the host and the guest operating system

    I am newbie to VMPlayer. I just installed VMPlayer 3.0.0 build-203739 on Red Hat Linux 5 (host). Then I created a VM comments Kubuntu (8.10). So far so good. In the VMPlayer window, I selected 'play Virtual Machine '. After this, the host operating system controls disappeared and I could see a taskbar on the top of my screen and I could also see Kubuntu startup (in an area of the small window in the center of the screen). The problem I'm running is that I'm not able to navigate outside of this area of the small window. I'm not even able to click/Select the taskbar of VMPlayer top of the screen. The mouse movement is limited to the area of the small window. How to and fro my host and the guest operating system? Is there a key combination? I finally had to stop my VM guest to return to the control of my host system. I guess it's a problem quite newbie that I am running. Any help would be greatly appreciated.

    Hello, welcome to the forum

    Host Windows to switch between comments and the OS (when you are in the guest operating system), you must use ctrl + alt.

    According to this link , it's the same thing in Linux host too.

    >Default VMware Player uses key combination Ctrl + Alt to jump out of the guest. Then CTRLAltdel is accessible via theAltInsert command. If you find this annoying, you can change the jump shortcut to CtrlAltshift by adding the following lines to your ~/.vmware/preferences:

    > pref.hotkey.shift = "true".

    > pref.hotkey.control = "true".

    > pref.hotkey.alt = "true".

    After your installation OS in the virtual machine, install "VMware Tools" on it so you will get better performance and some improvements (like moving your mouse out of guest to your host operating system operating system and Vice Versa, or be able to copy beyond host/guest, better resolution on reviews and...)

    I hope it helps a bit.

  • Bean Java properties class that extends data control cannot get data on the user interface

    Hello

    I'm writing a bean something like the following and trying to create a control of data off of it:

    package model.beans;

    import java.util.Properties;

    SerializableAttribute public class PropBean extends properties {}

    String ID;
    The name of the string;
    public PropBean() {}
    Super();
    setName ("TURBO");
    setId("123");
    }

    public String getProperty (String key) {}
    If (key.equalsIgnoreCase ('name')) {}
    return getName();
    } else {}
    return getId();
    }
    }

    public String getProperty (String key, String Valeurdefaut) {}
    If (key.equalsIgnoreCase ('name')) {}
    return getName();
    } ElseIf (key.equals ("id")) {}
    return getId();
    }
    else {}
    return Valeurdefaut;

    }


    public String getName() {}
    System.out.println ("GET =" + myIdName);
    Return myIdName;

    public void setName (String name) {}
    myIdName = name;
    System.out.println ("VALUE =" + myIdName);
    }

    {} public void setId (String id)
    This.ID = id;
    System.out.println ("VALUE =" + this.id);
    }

    public String getId() {}
    System.out.println ("GET =" + this.id);
    return the id;
    }
    }

    When I binds the name and id attaributes text of output values do not appear on the screen.
    But if I do not extend class properties and then on the piece of code just works very well.

    The same thing happened when I extended HashMap.
    I had to override the method getObject (Object obj) to make it work.

    However I am still unable to run when the class extends a class of properties.

    See you soon,.
    REDA

    Hello

    When you extend HashMap then create you a hash table. Properties extend from HashTable, which seems to be similar. Tehre is a reason why your class should extend the properties instead of use the Properies class as a resource reference?

  • HP Pavilion 15 laptop: HP Pavilion 15 laptop: System Restore completed successfully. The problem is not resolved.

    About 3-4 weeks ago, my computer found himself in a reboot loop. I was not online at the time where he was probably not due to an update.

    After going on the HP Web site, it was first suggested that the issue could be overheating due to dust. I followed the instructions but it does not work.

    Diagnosis is directed which has determined that there are no problems with the hardware or memory.

    Then the site suggested that I do a Refresh system or a system restore. I tried the cooling system. It did not work.

    I contacted HP Tech Support hotline and they told me to update the drivers. Drivers cannot be updated / installed (by me at least) in Safe Mode, if it does not work.

    Then told me the only choice I had was to do a Factory Reset/System Restore.  After the purchase of an external HARD drive and backup of my files, I tried to do the factory reset. I received a prompt to insert a disc, but computer did not come with a disc. If it does not work.

    Then I was told by support that I had to buy "recovery disc" or a new copy of Windows 8.1. Technical support said it was the only way to solve the problem. By chance, I found another video that shows how to access recovery tool of real system since menu troubleshooting at start-up.

    System recovery completed successfully. However, while creating the new installation of Windows 8.1 (implementation name, country, favorite colors, e-mail etc.) the original reboot loop problem started. If it does not work. Even worse, because the Windows installation is incomplete - and can complete because of the reboot loop - I can access more fashion is safe.

    Any help or advice would be greatly appreciated. Miracles would net you have my firstborn (eat too in any case).

    Okay, so I had to take the machine to a technician. What she said is that it was certainly not a hardware problem. Its best estimate is that my computer As witn infected a Trojan horse which subsequently transferred, entered the BIOS and corrupted partition.

    Short history of Tech, they fixed by redoing the BIOS and installing a new copy of Windows 8.1. I asked about the other options that I received. She explained that a remote technical support could not fix the problem, nor recovery disks could solve the problem.

    My advice to all who encounter such a complex problem, when you contact HP Support don't forget to request contact information for a local HP technician, licensed (I only asked for this in desperation by accident). Just in case your problem is not easily diagnosed or solvable, it might just save you some time, money and spare you confusion.

    As for how I got infected with the Trojan possible in the first place, no idea. The only thing I can think is that I've opened an e-mail looking strange but legitimate to someone I didn't know. However, it was about 6 months ago and the problem started a month before, so I at least do not know if there is a link. However, it is always good advice not to open strange e-mails. Note that the technician did say that even if I had Norton installed, it would not be able to automatically detect the problem. (I wonder if I called Norton technical support if they could have helped or pointed me in the right direction faster. But even once, any comments or information I received from HP technical support gave usable clues. "And refresh the system that has been proposed did uninstall Norton).

    So, I have a computer to work again. I hope this info can be useful to someone and avoid frustration. Thanks to everyone who took the time to read my post.

  • Satellite Pro U200-10I - how to disable the system at startup control upward?

    : x Hi,.

    I have Toshiba Satellite Pro U200-10I and I want to disable the control system, as it is a long time to start machine. Is there a way to Devil who?

    Nedd your help! : D

    Hello

    Just checking the system do you mean exactly?
    Is this based on Windows or BIOS based?

    If you mean the ScanDisk in Windows startup you can disable it in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager
    Change the BootExecute entry to: autocheck autochk *.

    After that restart the ScanDisk is disabled and doesn't appear at Windows startup.

  • How to keep the controls panel/glance through the changes of fonts more small-medium-large screen made through a window to customize the Windows operating system?

    Hello

    My application uses digital edition, ring and other controls with chains of control/label mainly composed of EditDialogMetaFont size = 11 (all optimized for the smallest font setting in a customization of the Win operating system window). When the user changes the font to the medium setting for example the police of all labels and controls is changed size = table 13 and all labels are misaligned with some labels even extending lines of Panel and thus become partially visible. How to deal with this situation, please?

    Thank you

    Martin M.

    The description of the metafonts sheds some light on this issue; It basically says that for a police metafont predefined size is not an absolute value and can change... The solution uses the fonts provided by the operating system, for example, Arial.

  • Front panel FPGA Boolean mechanical action is important to control the actions of a host RT?

    When a host RT controls an FPGA VI shipped through Boolean values on the face before of the FPGA VI, no matter what setting the mechanical action is used by the Boolean front panels?  For example, they all just act as "Switch When you press on" or the law "lock when you press on" as one-shots?

    Okay, it looks like I have a little bit of clarification to make.

    First of all, the patterns of waveform above are correct. As soon as the handshaking signal Host_Write if high, the data is written to the next clock cycle. At this point, "Lock" options are equivalent to eachother, and all the options of 'Switch' are equivalent to the eachother. Each takes 150ns to receive the signal of Host_Write.

    The only thing in my post above that is misleading is when I said that transitions occur at the same time. This is not true, as the writing must be serialy, 150ns apart.

    In case anyone is interested, I enclose the test and the test bench project. On your host machine, simply generate the files for the simulation construction-spec, then replace the tb_NiFPGASimulationModel.vhd generated by the one I've attached (this is the test bench). This should be at "C:\NIFPGA\simulation\FPGA_Boolean_Mechanical_Action\FPGA_Target\MechanicalActionTest\user". Given that forums don't add .vhd files, please rename the .txt in .vhd.

  • Can't place separator reference in the private class data control

    Any reason, I can't drag and drop a splitter reference leave my block diagram to a private open class data control? Basically, I'm ignored when I let it go, even if I see an icon 'drop' after that I drag the control.

    Well, I think I got smart and just placed a generic control Refnum into the command group, and then used the VI of the server class to identify it as a separator. Interesting how I could drag and drop references to the sub-panels and other types but not a divider.
