Why Enterprises Use KVM Switches with Cisco C9300 Switches

Managing enterprise switches requires direct console access, especially during outages or configuration failures. That’s where KVM switches come in.

What Is a KVM Switch?

A KVM switch (Keyboard, Video, Mouse) allows administrators to control multiple devices using one console.

Popular KVM Types

• USB KVM switch – small IT rooms
  
  

• Dual monitor KVM switch – NOCs & SOCs
  
  

• KVM-over-IP switches – remote access
  
  

• Datacenter KVM switch – large enterprise environments
  
  

Using a best KVM switch ensures:

• Faster troubleshooting
  
  

• Reduced downtime
  
  

• Secure access to Cisco switches
