Network Access

An engineer needs a switch interface to actively try to establish a trunk link with a neighboring switch. What command must be configured?

  • A switchport mode trunk
  • B switchport mode dynamic desirable
  • C switchport nonegotiate
  • D switchport mode dynamic auto
Explanation

On Cisco switches, switchport mode dynamic desirable puts the interface into a DTP state that actively negotiates trunk formation with the connected switch. dynamic auto is passive, trunk statically sets trunking rather than negotiating it, and nonegotiate disables DTP negotiation.
