    Quick question


    does layer 2 traffic operate if a gateway is specified.

    I have a windows machine, I have a static IP and and static Gateway specified.

    If my gateway goes down, can i still access all machines/traffic on a layer 2 network?

    Thanks!

    Yes. Layer 2 simply uses mac IDs....which is supported by switches. A gateway, by definition, would be a layer 3 device.

    Sounds like a homework question...

    Ok let me rephrase that,

    I know how layer 2 works, what im asking is

    What takes priority, layer 2 or layer 3

    If layer 3 failed, would layer 2 take over or is layer 3 not required when dealing with layer 2 traffic.

    There's no priority. All of the layers have to work in order for applications to communication. That's why the layers are there. Start at application, work down to layer 1, receive on layer 1 and work back up to application. It's a process, not a priority.

    If layer 3 fails, communication fails. Layer 3 would not fail in your scenario because the switch would be able to associate IP and MAC addresses of the local computers. A gateway is never involved.

    It's the process of going from layer 3 to layer 2, yes.
