Cisco FIREWALL 2.0: ASA Interface Redundancy and Active/Standby Availability
This course is included in our On-demand training solution.
To support high availability on the Cisco ASA Adaptive Security Appliance, you can use several high-availability features on the appliance. EtherChannel enables you to improve the bandwidth from the Cisco ASA Security Appliance to a switch that also supports EtherChannel and it provides logical interface redundancy. Other high-availability features are redundant interfaces, in which you can pair two physical interfaces to provide interface-level redundancy. One interface in a pair is designated as active and one is waiting as a standby member. If the active interface fails, the standby interface takes over and starts forwarding traffic. This course describes how to configure EtherChannel and redundant interfaces on the Cisco ASA Security Appliance.
To provide device redundancy, you can deploy Cisco ASA Adaptive Security Appliances in an active/standby high-availability failover configuration. Using this feature, you can pair two Security Appliances, where one is active and forwards user traffic, and the other is in a hot standby state. With active device failure, the standby device will take over. If the active/standby failover is deployed and configured correctly, users may not experience any network disruption. This course provides a description of the active/standby failover and then demonstrates how to configure, tune, and troubleshoot active/standby failover functionality.
