Cisco Switching – switchport nonegotiate

February 19, 2009

Dynamic Trunking Protocol (DTP) is a standard feature of Cisco switches and allows two switches to dynamically configure interfaces interconnecting each other to be trunked ports.  DTP has 5 modes; Auto (default), On, Off, desirable and nonegotiate.  These 5 modes all have a purpose.  I have layed out the groundwork below:

To configure this on your switches, issue the following:

configure terminal
interface g1/0/49
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate

Hopefully this was somewhat worthwhile.  It is very basic so I apologize but this is the easiest way to give you the needed information without boring you to death 🙂
