Security of the port on a SF300 problem

Hello world

We recently bought a new SF300, the main goal was to using the security of the port as a CNA.

I expect to be able to define a list of allowed MAC addresses, but unfortunately, it is not the case.

I used the "Classic Lock" port security.

knowing that I can't have all the computers being connected at the same time (for cause of displacement), when a person to be allowed is here I am forced to disable security so that the switch can learn its MAC address.

the problem is that when I do, the MAC addresses that are already learned are forgotten if disconnected from the LAN and when someone changes his position in the local network, it is blocked from access to the network.

I remember that my goal is to give access to the network based on the MAC address or the domain name (allow computers part of OurDoamin.com).

N.B: In our architecture, each room has a small switch and these switches are connected "central one" which is the Cisco SF300.

Thank you.

Dynamic arp for this inspection. Specify a mac IP on the trust list, the client connection to the "secure" ports (meaning subject to inspection of the arp) then do 'secure' interconnection ports (that is, not subject to inspection arp).

I'll tell you one thing... before playing with DAI, make sure to enter at least the host you are using, otherwise you will be hose to the top of this switch.

  • Problem with security of the ports and disabled learning MAC addresses?

    Hello

    Is there a problem, or incompatibility, if you configure the port-security on "n" ports that belong to X vlan and also disable mac-address-table of learning on this vlan?

    Someone did he do reference, links or PDFs on this problem?

    Thank you very much

    Best regards.

    Hi Javier,

    As I showed above, the combination is valid. I did not all static entries in the security of the ports, but all entries learned through port security will be shown as static on the show see the mac address table. All dynamic learning is disabled.

    I don't know what kind of security problem, that you try to resolve, but the configuration is valid.

    In this case, you will need to use the AddPortgroup method.

  • Portage Z30-A-13W connected to the high speed Port Replicator III - USB problems

    Hi all.

    We recently bought a new Portage Z30-A-13W and Hi-Speed Port Replicator III.
    Setting network and graphics work correctly with port replicator, but the USB ports don't work at all.

    I tried the port replicator USB 2.0 and USB 3.0 and I can't seem to work with a keyboard, mouse, USB key or a mobile phone.

    In the case of mobile phones, it is also no output power of the ports that the mobile does not start to load.

    At any one another experianced this problem and what was the resolution.

    Thank you very much

    Hello

    As far as I know additional drivers are not really needed to use the USB ports.
    This is why I m wondering why don t USB ports work.

    It might be possible that ports high speed Port Replicator III USB are faulty, but to be honest, I can't imagine that all 6 USB ports may bad work at the same time.

    So maybe it s a software problem.
    First of all, I would recommend the default BIOS and check the USB legacy support for keyboard and mouse could be activated.
    After access to the Device Manager and remove / delete the USB hubs and controllers in the list of devices.

    Keep high speed Port Replicator III connected to the computer and restart the device.
    Usually, the system should recognize automatically deleted USB ports and must update the drivers of USB ports.

    I hope that the USB ports don't work after this short workaround solution.
    Keep your fingers crossed.

  • Problems with the port replicator USB 2.0 after installing Windows XP - SP2

    Hello world

    I have a Satellite M30 742 with MS-Windows XP Professional installed. I plugged most of my external devices to him through a port replicator Toshiba USB 2.0. Everything seems to work fine until I installed Service Pack 2.

    Therefore, starting my laptop computer is an adventure to recognize random port replicator: usually four USB ports are recognized, but the ports series and parallel, keyboard and mouse ports are ignored, with a message "unknown USB device".

    Uninstalling and reinstalling, them or their drivers are a vain effort, since Windows keep ignoring them.

    However, in other occasions, they are recognized without problems (even if windows insist on installing their drivers each time that it finds, even if I have already installed a large number of times).

    Please, you have an idea to solve this problem * boring * problem?

    Thank you very much in advance,
    Ricardo.

    Hello

    what you might try is to reinstall the chipset driver because I think that the USB is connected to the chipset.

    In my opinion the Windows upgrade had changed the pilot USB from Toshiba a MS a. So the Port Replicator is not recognized all the time.

  • Problems with an external monitor with the Port Replicator III and M100

    Hey all.

    I just returned from a trip where I took my laptop. Plugged into the Port Replicator port, started and everything was fine. Then after an hour or two, the monitor stopped receiving a signal. I repositioned the laptop and everything was good again. He then loses signal once again, and I was not able to get a signal via the port replicator since.

    The monitor works fine through the hole at the rear of the M100.

    I checked the pins on the Port Replicator port and portable, none folded and tried to clean any dust etc. Still no signal to the monitor.

    Someone has ideas of how to do to solve this problem?

  • Tecra A8: Problem with the USB printer connected to the Port Replicator III

    Hi all

    I have a problem with my Tecra A8, year Advanced Port Replicator III and a USB printer. With the printer connected to a USB port on the Port Replicator, I have to wait 2 minutes for printing to start. When it is connected directly to a USB port on the laptop and the laptop disconnected from the Port, printing starts immediately. I have the latest drivers from the Isensys of Canon LBP 2900 installed and Windows Vista professional as the operating system.

    I called the technical support of my country, but her is not recorded similar problems.

    A person with similar problem? Some help would be very appreciated.

    Thanks in advance.

    Hello

    Seems like a strange question... Already done the standard procedure in the event of such errors? :)

    The standard procedure is somehow similar to the following:

    -Update your BIOS
    -Update all the drivers for your machine
    -Update your printer drivers
    -Update your operating system

    If all else fails, then try an another Portrep if available, maybe you need to contact your dealer for an another portrep for the test.

    Something like this should be your way. And then you sucessfully made a TROUBLESHOOTIN´ ;)

    I'd be happy to hear feedback from you on your situation...

  • IR hotsync problem: "because the port is in use by another application."

    I finally got my system operation.  Sony Clie TJ - 25 pda, Palm Desktop 4.1, Windows 7 64 bit.  Very delicate balance.  I failed to install the new software released by aceeca.  I finally got it by infrared hotsync.  Several times.

    Now, today, I get the message on the Clie: "could not start the hotsync operation because the port is in use by another application."

    I saw this thread and in fact ensure that the transfer of images using a digital camera box is unchecked.  It still does not.  The icon hotsync in the lower right part of the screen, when I check that IR is checked, nothing else is.  It still does not.

    Thoughts?  Ideas?  Suggestions?

    Cidercat I had this happen to me with bluetooth hotsync before. I listen to radio, transfer files and surf the web with bluetooth. I could solve the problem by turning off the bluetooth, then turn it back on. Sometimes a warm reboot might also work. I came across a free application for the Palm tree named NetworkDown. It closes completely all active sessions down. You type right on the icon to run it. It works on my TX.

  • When I try to scan with my CanoScan N640P ex scanner I receive a message indicating the Port to the printer that is used by another device. How can I work around this problem?

    When I try to scan with my CanoScan N640P ex scanner I receive a message indicating the Port to the printer that is used by another device.  How can I work around this problem?

    Hi ejp70,

    1. did you of recent changes on the computer?

    2. to when was the last time the scanner was working fine?

    3. you have any other printer\scanner connected to the computer?

    If you have any other printer\scanner connected to the computer, disconnect them and check if it works.

    I suggest that you uninstall and reinstall the scanner to the computer, also make sure that you install the latest drivers for scanner on Canon website.

  • problem with the ports of the two SLM2048

    Hello:
    I have a problem with two models of SLM2048.
    I only as configured in these devices was 4 VLAN and link aggregation port between these devices.
    I detect some Don t work ports (I connect to a workstation in the port and the Don t upward, but in the other port if upward)
    Could be a hardware failure? or maybe the switch block these ports?
    Best regards

    I'm not sure that I fully understand your port problems.  Is this a failure of single port or you have a problem of end-to-end between ports on two different switches?

  • Re: Tecra A10 - USB problem on the port replicator

    I have a Tecra A10 and sometimes, when I work with her, the devices USB stopped responding if they are connected to the port replicator.
    If I connect them to the laptop, they work fine.

    I tried to update the BIOS but now when I turn on the laptop it freezes when Toshiba red letters are displayed on the screen. I can work with the laptop properly deattached starting from port replicator.

    Have you tried to load the default settings in the BIOS after the update?

    If you have external devices connected to the laptop they remove and try again in the duplicator.
    Maybe you should also update your laptop chip set driver. You can find them on the Toshiba site.

  • Problems with static IP setting for the port forward through 2 routers

    I currently have cable internet connected to a router (Linksys E2000 w / v1.0.03 firmware). This router is connected to another router, a Linksys E3200 with firmware v1.0.02. In order to correctly forward ports through the E3200, I understand that I need to set up a static IP address on the router.

    I almost followed the steps in this video, but when I enter all the IP addresses for the static IP address settings, it allows me to access the router configuration page. I try to get the new IP address that I gave (which he tries to move automatically once I have save settings) and the connection times out. I am able to access internet otherwise, however. From here, I have to do a factory reset on the router and start from square one.

    Anyone have any ideas? I'm quite frustrated and would like to get ports forwarded so I can get my server properly set in place.

    1. If it has connected LAN - LAN you will need to disable the DHCP server on the E3200.

    2. the best option would be to use the 'bridge' on the E3200 mode (in the latest firmware) and connect the internet port to the main router.

    3. If connected LAN - LAN (or in Bridge mode) all internet related functions on the E3200, including ports are not relevant. There is no need to set up the port on the E3200 redirects. All shipping is done only on the E2000 and nowhere else.

    4. What is the address LAN IP of the E3200? What is the address LAN IP of the E2000?
