Layer 3 switching training course description

A hands on switching course for those already familiar with the basics of Ethernet switching. The course focuses on L3 switching along with the QoS and security features that layer 3 switches can add to the network.

What will you learn

• Explain how layer 3 switches work.
• Troubleshoot layer 3 switching.
• Implement QoS on switches.
• Secure networks with L3 switches.
