How to block all communication port

Hello

I've got sg - 300 cisco cisco switch. I want to make connections between 2nd port on the 3rd and the block between 3rd and 4th port communication.

In short, 2nd port must Access all ports located in the same switch, 3rd port not to communicate all ports except port 2.

and 4th port should not communicate all the ports except port 2nd...

How to do this? is this possible... Please help...

Hi sundar, this can be done with protected Harbour located by editing a port under the administration of the track. This will isolate all individual ports to see each other while using the uplink port. If you need one of these ports AP to connect then it will need to access lists.

  • I would like to know how to block a particular website of all browsers.

    Original title: blocking websites

    I need to know how to block a particular all browsers Web site. I don't want to go into each browser to configure the modules or extensions. I want a challenge. Quick and easy. Something I can do when I add user accounts.

    For example, I've blocked Acronis.com (see figure)

    The host file is located in window\system32\drivers\etc

    When a browser attempts to access a site that is blocked, he'll tell: page not found and error

  • How can I get Thunderbird to stop blocking all my messages... I have to go into options and accept each

    I would like to know where to change this setting.

    As Thunderbird is not blocking e-mails, I'm sure you don't want to block all my messages.

    Maybe you say Thunderbird is blocking remote content which it pays to safe guard your security and your privacy, for very obvious reasons.

    In this case, you would see a message "to protect your privacy, Thunderbird has blocked a remote content in this message.
    The 'options' button gives you a few options.
    You can choose to:

    allow the remote content for that message only
    

    or always allow for that particular e-mail address.

    You can also disable remote content blocking, although this is not recommended - the risk is your take. Please, do not assume the e-mail analysis will cover you.

    Tools > Options > privacy
    or
    Menu icon > Options > Options > privacy

    • "Content of mail slot
    • Select: "allow remote content in messages.
    • Click OK

    Please read this before you select the option to turn off - you must be clear about what he does.

    Not knowing which version of Internet Explorer you have I can't help here to save time I'm you pointing to this tutorial.
    In the new versions of Internet Explorer, drag the slider in the Internet Options via the tabs in privacy.

    In Firefox, it should be the tab privacy as well, but in the preferences

  • How to completely control the PORTS COM of BT?

    This is related to several versions of the Toshiba, but in this case, it is with 5.10.14FP1, installed on a Windows Vista.

    When you start the Bluetooth local COM-Port-Control Panel, the list is filled with eight COM ports:

    COM10 exchanger information Toshiba BT Port (COM10)
    Com11 exchanger information Toshiba BT Port (COM11)
    COM12 exchanger information Toshiba BT Port (COM12)
    COM13 exchanger information Toshiba BT Port (COM13)
    COM14 exchanger information Toshiba BT Port (COM14)
    COM20 HSP Toshiba BT Port (COM20) Manager
    Com21 Toshiba BT Port (COM21) HSP Manager
    COM22 Manager of HSP Toshiba BT Port (COM22)

    If I try to delete one of the existing COM ports tells me that it is created by Information interchange or Manager of HSP.
    And if I add other com ports to the BT stack, they seem to count for COM40.

    However, I need to be able to fully control port numbers the specific COM assigned to different interfaces I add... and I most certanly didn't eight predefined ports.

    So, I have the following questions:
    (1) how to remove eight predefined ports?
    (2) how to change the com ports new I add to use COM1 and beyond. (No, port settings normal in the hardware control panel is not an option that is not there).

    I look forward to your reply...

    Daigoro.

    First of all I think that it is not a good idea to delete COM ports that are used for communication. If the services according to will not work afterwards. You can of course create new server COM ports if necessary and also configure client COM ports to fit your needs. Just use the custom instead of Express Mode Mode configuration wizard. Now you can determine what COM port should be used for your device. COM1 is often already used by the system, for example the built-in modem, so make sure that it's free!
    The tool you are talking about is also available in VISTA. See "Control Panel-> control home Panel-> hardware and sound-> Bluetooth Local COM" for her.
