Local Loopback Disable

Local Loopback Disable allows users to force the disablement of local loopback on the virtual port (vport). This disables both unicast and multicast loopback in the hardware.

  • To enable Local Loopback Disable, run:

    Copy
    Copied!
                

    echo 1 > /sys/class/net/<ifname>/settings/force_local_lb_disable"

  • To disable Local Loopback Disable, run:

    Copy
    Copied!
                

    echo 0 > /sys/class/net/<ifname>/settings/force_local_lb_disable"

    Note

    When turned off, the driver configures the loopback mode according to its own logic.
