Cisco ASA High Availability HA Failover Configuration.

Description

Cisco ASA (Adaptive Security Appliance) is a security device that provides firewall, VPN, and other security services to protect networks and data. Understanding how to configure and manage Cisco ASA firewalls is essential for network administrators and security professionals.

In these labs, you will get hands-on experience with configuring Cisco ASA firewalls using real-world scenarios. Each lab is designed to cover specific topics, such as basic configuration, security policies, NAT, VPN, high availability, and more. By completing these labs, you will gain practical skills and knowledge that you can apply in real-world network environments.

Verification

Verify failover status and synchronization between active and standby units using the show failover command. Test failover functionality by disconnecting interfaces or shutting down the active unit to simulate failover. Verify reachability of devices on the Inside, Outside, stateful link, and stateless LAN networks from both firewalls.
