Cisco CCNP/ BCMSN Exam Tutorial: Dynamic Trunking Protocol
Cisco CCNP/ BCMSN Examination Tutorial: Dynamic Trunking Method (DTP)
When you're researching to pass the ramsey theory capital BCMSN exam en route to earning your CCNP accreditation, you're mosting likely to add to your CCNA knowledgebase every action of the way. Nowhere is that more than setting up a trunk in between two switches.
You understand that IEEE 802.1 Q ("dot1q") and ISL are your 2 options of trunking methods, and you know the main distinctions between both. What you could not have actually understood is that there's a third trunking method that's running between your Cisco switches, and while it's a clear procedure to many, you had better learn about it for your BCMSN and other CCNP exams!
The Cisco-proprietary Dynamic Trunking Protocol (DTP) proactively tries to work out a trunk link with the remote button. This sounds terrific, yet there is a price in expenses-- DTP frameworks are sent every 30 seconds. If you choose to configure a port as a non-negotiable trunk port, there's no demand for the port to send out DTP frameworks.
DTP can be switched off at the interface degree with the switchport nonegotiate command, yet as you see below, you can not turn DTP off till the port is no more in vibrant preferable trunking setting. (Dynamic preferable is the default setting for the majority of Cisco switch ports.)
SW2(config)#int quick 0/8
SW2(config-if)#switchport nonegotiate
Command rejected: Dispute between 'nonegotiate' and 'dynamic' status.
SW2(config-if)#switchport setting?
access Establish trunking mode to ACCESS unconditionally
vibrant Set trunking mode to dynamically negotiate gain access to or trunk mode
trunk Set trunking mode to TRUNK unconditionally
SW2(config-if)#switchport setting trunk
When you're collaborating with Cisco switches over in a home lab or shelf rental environment, run IOS Aid consistently to see what alternatives are readily available for the commands you're practicing with. Cisco switch ports have several choices, and the best means to discover them is with one straightforward symbol-- the enigma!
