Thread: Yast2 - Show visible port identification?

    Default Yast2 - Show visible port identification?

    Hi,

    Can anyone tell me if this (see image below) button works? If it does, does it do what I am assuming that it does?
    That is, it blinks the led's on the respective network card, so that I can mach the physical connector with the currently selected ethernet port.

    Regards, Martin

    PS - This is currently 13.1. But I have not seen any evidence of working in any of the previous releases or alternative hardware configurations.

    That's what I assume.

    Well, you made me test it (12.3). I tried it on my second socket, and it
    did not blink.

    If you create a bugzilla on it, I'll add a "me too".

    Hi
    Does it work with;
    Code:
    ethtool -p <interface> 5
    Does the interface and module have to support this feature?

    Maybe.

    In which case, YaST should say so, so that we don't squeeze into tight
    and difficult places looking for the blinking led.

    Thank you both,

    Yes - That's to "gotcha" Malcolm!

    Checking each of my interfaces, I find that my Intel Server cards do flash with the ethtool commands AND Yast2 GUI.
    However, with my cheepie PCIe cards, I get "Operation not supported" on the ethtool command line, that you don't see in the Yast2 GUI.

    Regards, Martin.

    PS - What's with the new (13.1) ethernet port naming scheme?

    The new version of udev is what changed the naming. On machines with more than
    one identical interfaces, the choice of name could be different from boot to
    boot. On headless servers, this was a real PITA. To correct that, udev was
    changed to make the name be dependent on the bus, which will remain constant
    unless the card is moved. Thus on one of my systems, lspci shows the following
    for the network card:

    00:07.0 Bridge: NVIDIA Corporation MCP61 Ethernet (rev a2)

    and udev names it enp0s7 for EtherNet Pci bus 7 Subdevice 0.

    If you want the old name, you should write one of the old-style rules for
    /etc/udev/rules.d/70-persistent-net.rules. The necessary line is

    [code]
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
    ATTR{address}=="XXXXXXX", ATTR{dev_id}=="0x0", ATTR{type}=="1",
    KERNEL=="eth*", NAME="eth0"
    [/code/

    That should all be on one line, and the XX's replace with the MAC address of
    your device.

    Thank you for the explanation.
    And, no, I've no need to change back to the old naming system. Bit of a fan of udev...

    You can do it also in YaST. Netowrk config, edit entry, Hardware tab,
    press "change" button. Actually, it writes that file:

    Code:
    
    > Eleanor4:~ # cat /etc/udev/rules.d/70-persistent-net.rules
    > SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:5f:45:90", ATTR{type}=="1", NAME="eth0"
