You know that IEEE 802.one Q (" dot1q") and ISL are your 2 possibilities of trunking protocols, and you know the key dissimilarities in amid the two. Specifically what you might well not have really recognised is that there is undoubtedly a third trunking approach that is working between your Cisco switches, and however it can be a distinct approach to a whole lot of, you had greater know about it for your BCMSN and other CCNP exams!

The Cisco-proprietary Dynamic Trunking Protocol (DTP) actively attempts to negotiate a trunk url with the distant alter. This appears good, but there is an expense in overhead - DTP frames are transmitted each and every single thirty seconds. If you make a determination to established up a port as a non-negotiable trunk port, there is certainly no necessity for the port to mail DTP frames.

DTP can be turned off at the man or woman interface diploma with the switchport nonegotiate command, but as you see underneath, you can not flip DTP off until eventually ultimately the port is no lengthier in energetic preferable trunking strategy. (Dynamic preferable is the default mode for pretty a couple of Cisco swap ports.).

When you are functioning with Cisco switches in a house lab or rack rental environment, run IOS Permit routinely to see precisely what solutions are available for the commands you come about to be operating in direction of with. Cisco modify ports have various decisions, and the exceptionally biggest way to discover out them is with a person specific essential sign - the enigma!
