http://cs.co/catalyst-center-youtube

Agenda

• How do I manage my complex, hybrid

networks with Catalyst Center?

• Is there any new Catalyst Center Physical

Appliance?

• How do I easily deploy Catalyst Center on

AWS and ESXi?

• How do I secure and manage my

deployments on AWS and ESXi?

• How does HA work with Catalyst Center on

AWS and ESXi?

• How do I migrate from Physical Appliance

to Catalyst Center on AWS?

• How do I backup my Catalyst Center and

restore if needed?
