  1. You have a very unique way of explaining, Clear and direct to the point. I am very grateful.
    Thank you

  2. Dear Rene

    i'm new here i finished before some week from CCNA I want to study CCNP with you the explanation is very good.this command:

    switchport trunk encapsulation dot1q

    Is not working in my packet tracer how can I make a switching lab ??

  3. Hi Mohamed,

    There are two trunking protocols, 802.1q and ISL. Some newer switches only support 802.1Q and in that case this command will be unavailable.

    It's also possible that packet tracer doesn't support it, it's a simulator after all. It doesn't matter too much though...when this command doesn't work then the switch will use 802.1Q when you configure the interface as a trunk.

  4. Hi Mohamed,

    IOU will work, the L2 image supports most of the switching commands. VLANs and trunking is no problem.
