You are heading to consist of to your CCNA knowledgebase each and every section of the way when you may well be learning to transfer the BCMSN assessment on the way to earning your CCNP accreditation. Nowhere is that a great deal more than ecosystem up a trunk involving 2 switches.
You know that IEEE 802.one Q (" dot1q") and ISL are your two alternatives of trunking methods, and you know شركة الامل للتوريدات in between the two. What you might maybe not have recognized is that there is a 3rd trunking protocol which is functioning amid your Cisco switches, and when it is seriously a apparent therapy to loads of, you had far better know about it for your BCMSN and other CCNP checks!
The Cisco-proprietary Dynamic Trunking Protocol (DTP) actively makes an attempt to execute out a trunk relate to the distant swap. This appears to be excellent, but there is an value in overhead - DTP frames are sent just about every thirty seconds. If you make a final decision to established up a port as a non-negotiable trunk port, there is certainly no want to have for the port to deliver DTP frames.
DTP can be switched off at the interface diploma with the switchport nonegotiate command, but as you see underneath, you can not swap DTP off until the port is not in vivid desirable trunking technique. (Dynamic appealing is the default process for a ton of Cisco change ports.).
SW2( config) #int swift /8.
SW2( config-if) #switchport nonegotiate.
Command turned down: Conflict about 'nonegotiate' and 'dynamic' standing.
SW2( config-if) #switchport manner?
get Set up trunking manner to Access unconditionally.
dynamic Established trunking manner to dynamically negotiate attain or trunk system.
trunk Founded trunking fashion to TRUNK unconditionally.
SW2( config-if) #switchport fashion trunk.
SW2( config-if) #switchport nonegotiate.
When you may possibly be operating with Cisco versions in a household laboratory or rack rental location, operate IOS Support consistently to see what choices are designed offered for the commands you are experimenting. Cisco transform ports have a variety of selections, and the greatest way to find out them is with just 1 quick symbol - the enigma!
