    What is the default switchport mode on Cisco switches? Does it varies per switch model?

    zyrk

      I have read/heard different things about this defualt configuration.

       

      • The CCNA Exploration Companion Guide: LAN Switching and Wireless book says on page 149 (Trunking Modes) that the default switchport mode is trunk.
      • Jeremey Cioara says on the CBT Nuggets CCNA video series (Switch VLANs: Configuring VLANs and VTP, part 1) that the default switchport mode is dynamic desirerable.
      • I am seeing on Packet Tracert that the default switchport mode is dynamic auto.

       

      So which one is it? Does it varies per switch model?

       

      Thanks for your responses.
