  • 1.  MAC FILTER X450e

    Hello everydoby,

    Actually, I have the Extreme x450e in my local network.

    I want to put the mac address filter system for limit the number of machines to connet in my LAN.

    After several research, I realize that some functionalities are absent.
    Specially, the "MAC lockdown" command .

    So I suppose that I don't have the recent version of the firmware.
    Actually, I have the 15.3.3.5 version .

    So, if you suppose that i have a old firmawre, can you tell me the last version of the OS please ?

    Advance thanks,

    Ragavan Sriram

    Ragavan,

    The X450 series switches are supported till the latest and current patch release of v15.3.5.2-patch1-9. This would be the recommended version.

    MAC Address Lockdown can be achieved using the command:

    configure ports vlan

    Hi Taykin Izzet, I'm back :)

    In fact, when i use the action of your command, I just have blackhole and stop-learning.

    Other thing, when I fix limit-learning 1 in a port, the switch don't block the second machine.

    It's very strange, do you have any idea ?

    Advance thanks,

    Ragavan,

    Please try clearing the fdb entry on that port and test again.

    clear fdb ports

    The following are some examples:

    First example, configures limit learning on ports 1 through 10 and 22 through 23 on the default VLAN. The port will learn two MAC addresses before the port is blackholed.

    # configure port 1-10, 22-23 vlan "Default" limit-learning 2 action blackhole

    This second example, configures limit learning on slot 1, port 1 through 10, and slot 2, ports 22 and 25. The port will learn 1 MAC address before its stops learning.

    # configure port 1:1-1:10, 2:22,2:25 vlan "default" limit-learning 1 action stop-learning
