11. Now the LACP bond will have a yellow indicator after you click Apply. In this example, the bond configured itself with an IP Address of 169.254.67.24 with a class B subnet mask of 255.255.0.0. This will happen by default when there is no DHCP server and the client uses the self-configured IP address. All you need to do is assign the correct IP address and subnet mask that corresponds to your 10Gb network.
