Switching

Course Description


These lessons cover everything that has to do with switching. We start with the basics of how switches learn MAC addresses, what VLANs and trunks are and how spanning-tree is used to create loop-free topologies. You will also learn more complex topologies like SDM, CEF and stackwise.

Course Highlights

In this course you will learn:

  • The basics of switching, how a switch learns MAC addresses.
  • How we use VLANs and trunks to separate traffic.
  • How to use VTP to synchronize VLAN information.
  • How spanning-tree creates loop-free topologies.
  • How to protect your switches against a variety of attacks.
  • Complex topics like SDM and CEF.
  • And many other topics…
